1800 I completely didn't notice that the rook was hanging so guess I failed my rating level, but at the same time I do very often notice such things in games.
I saw 1... Bxf3, 2. Qxb4 ... Rg8 3. g3 but rejected 3... Rg4 because of 4. Qxg4, and I can't see an immediate win for black. Instead, I proposed 3... Be4 cutting the queen off from the kingside and threatening 4... Qxh4. If now, 4. f3 then 4... Rxg3, 5. Kf2... Rxf3, 4. Ke2 (4. Ke1 ... Qxh4, 5. Kd2 {5. Ke2 ... Rxf1 followed by 6...Bd3} ... Qh2, 6. Ke1 (6. Kc3 ... Qxc2, 7. Kd4 ...c5) ... Rxf1, 7. Kxf1 ... Qh1. If instead, 4. Kh2 then now 4... Rg4 threatening 5 ... Rxh4. Now 6. Kh3 is not possible due to 6 ...Bg2. This wasn't the solution, but, since I am an average club player, I may have missed other candidate moves for white after 3 ... Be4. Nonetheless it was enjoyable trying to calculate variations in such positions using methods from another RCA course (Calculate til mate). Please provide more videos like this as they help me develop my chess.
Same for me, I assumed the opponent would recapture the bishop and I could get the checkmate right away. It's strange that I didn't even notice that my rook was vulnerable. I would really like to see more of these puzzles. It looks like a very good way to improve your game.
If you took the knight with the bishop KNOWING YOUR ROOK ID HANGING then ur 1600 however, in your case you had no clue your rook was hanging making you 800 rated as he mentioned before...
One problem i find with puzzles is, that you just know theres something good in that certain position, so you kind of eliminate all the ''boring'' moves that dont do anything in the first place. In a normal game u might not see the forcing line, because you dont know theres something concrete on the board. I like those kind of videos though, please do more.
That's the issue I had as well. I was immediately able to write off defending my rook, because this puzzle was so, so blatantly forcing Oh No My Rook checkmate variations. It didn't take me very long to find that White has very few defensive options, relying on that powerful b4 defense and check threats to try and slow down your attack. However, I got stuck on g3 rg4, because that was the point where I was unable to find white's best move according to this video and didn't see a checkmate line. Using chess classroom I followed the line further, and white's best move is actually to sacrifice on qxg4, preventing the checkmate threat but leaving a bishop queen vs double rook endgame. Now I'm not claiming I'm some kind of genius, I wasn't able to distinguish whether or not I was on the right track past bxf3 until using stockfish and watching the video, so while I'm happy with the 1600 rating this video would give me, I still find it very funny that stockfish disagrees with RCA about the strongest variation for white.
Indeed. However for this particular puzzle, you might eliminate good moves too early like Bxc6， because they looked suspiciously obvious. You would think 2000+ players would make very unusual first moves probably with a huge sacrifice. In real games, Bxc6 will be played out more easily, even most may have never calculated its most tricky variations. On the other hand, solving puzzles can actually make you constantly seek attacking opportunities in real games. You will become much more aggressive and sharp.
the whole point of doing puzzles is so you develop your pattern recognition, so that while in a game you go "oh wait, there's gotta be a tactic here". And I mean, you should always try not to make "a move that doesn't do anything in the first place" when you are playing XD
Yes, that is always problem with puzzles. I was able to quickly find Rb4 and Qxa4 variation and that white queen will be out of play and without perpetual after Kb7, but I have never reached above 2100.
Haha... I got the 1600 rating on this test. But, I am not even a chess player. I have no rate, and I think my game level is worse than mine while doing puzzles.
7:48 I did calculate upto this level but there is no way on the face of this earth that I’m 2600. If I’m 2600, then my brother who beats me on a regular basis is Magnus.
So here is what is strange. I actually calculated all the way TO the Qxh4 variation! But I totally missed the fact that my rook was hanging. As it turns out, it didn't matter -- but I'm not sure if my rating is 2700 or 800. 🙂 Very fun and practical puzzle!

The puzzle rather evaluates your middlegame skills. If your endgame skills or opening knowledge is lacking, it won't show it. Still, the test makes a lot of sense.
I've only seen a couple of vids, but I have a gut feeling this has the potential to be more useful for higher-rated players than Gotham chess, despite the popularity.
More chess puzzles like this one are always appreciated. Chess games at the grandmaster level which did not result in a draw, are always good as a learning tool.
I found another variation: Black takes knight, white queen takes rook, Black Bishop takes the pawn that didnt strike back from earlier, white takes black bishop, Black rook comes to g8 (giving a check), white king to 1h (there arent any other moves) and the black queen takes pawn at 4h giving checkmate. Now please respond to this cuz I spent much time and I really wanna know my rating (I cant think this clearly during games). 😢
you should do more of these, but also throw in ones where the best moves are not forcing. in puzzle positions like these you overlook boring moves because you know it’s a puzzle
Saw the bishop take, saw the follow up and saw the queen takes. I didn't calculate whites checks with the queen which can sometimes be my downfall. My strength i feel is tactics, weaknesses being moving too fast, not fully calculating, or as you mentioned hoping that an attack works out
@@bradburns491 similar for me. I saw the pawn would be pinned after rook h2, so white couldn't take the bishop any more after taking the rook. So the attack would go on even after the queen defends the pawn when taking the rook. But I didn't see the defensive move g3.
Exactly the same thing - I found Rg4 as the move that made Qxh4 viable in the first place and then went "eh, the King can run away behind the queen and rook" (though I was thinking of Qb7 and not Qc3-c5 for White). It is important for us all not to play hope chess, but it gets really easy to when your visualization has to go far and you start feeling doubts. PS: I am a bit under 1700 FIDE.
i first thought 1800 level, but after seeing the 2300 move Rg4 (which i have no idea how i missed), i immediately found the 2700 level Qxd4. after seeing the board im ok at calculating but im absolutely horrible at visualizing the board after 3 or so moves since i get easily confused
Obviously if you don't spot the intermediary steps, you cannot claim the to understand the highest level moves. Because if you blunder before that, you wouldn't reach that position anyway.
I have thought that visualization was very important to become a good chess player. But I don't see much teaching on how to improve visualization. Is it something you are born with and either have or don't have or can it be improved ?
@@lw216316 there are 2 things here.. One is direct visualization based on the position.. It's not that difficult.. But when you start making moves in your head and visualize them, it's different thing all together...
@@AP-eb8hd yes, its the 'in your head" the imagination part - is that a quality a person is born with or can improve, is so how do you do that in chess?
What I learned form this puzzle is that I see most of the components of the problem, but I short-change the calculations when I see a move that is clearly favorable.
I also chose bishop takes & totally overlooked the queen threatening the castle. I seem to be hanging in the area of 750-850 in rapid and 1325-1450 for puzzles (hard level). I was taught to play (basics) chess but only now in middle adulthood started to look into chess in a more (I do have an insatiable need to play daily to get my fix) academic sense and seem to have a real addiction to it since moving my first pawn inJanuary 2023. I would love to join some chess club in South East Michigan at some point with aspirations of continual growth & study. Shooting for a 1600 ELO for an initial goal. I ❤ the video.
For newer players, try playing slower games and try to calculate 2 moves for every "power" piece. Eventually you start getting a feel for things and just start to see the threat without looking for it which you should just use to read deeper. Pawns I feel are pretty instinctual most of the time for even newer players already, but lots of people miss forks or a surprise take.
Calculated everything up to failing to find Rg4. As a result, went back and thought, okay, Bxf3 works as long as I avoid Qxb4 because it defends h4. So I thought c5 (1000 rating) or Qe7 (not mentioned) would allow Bxf3 on the next move. This meant calculating Ng5, when Bxg2 is either a free pawn or white runs into Kxg2 Rxh4 (which either wins or exchanges down until you're 2-3 pawns up depending on how white plays - white has e4 to defend with the queen and the king can try escape via f3). Of course, c5 is met with Qe2... While an 1800 might find Rg4 in the "think" after g3, it's hard to say an 1800 would have chosen this line other than by "hoping it works out", which you don't recommend doing. As such, I chose Qe7 because Qc5 looked more promising after white's Qe2 than c5. So, what's my rating?
This was awesome! I just found this channel yesterday. I usually watch Hikaru but your videos are more like classroom math exercises. I like how organized and concise, while still being thorough, they are. I am around 800 elo, and you’re right that I did hang my rook, but upon noticing I was able to calculate the refutation of bishop takes knight (queen takes rook) and then up to white playing g3 and I thought the attack was over. I didn’t see rook to the fourth rank attacking the queen, and while I did consider sacking on g3, I never considered sacking on h4 or anything else. I will keep improving!
I calculated everything except the king running away which I did a little differently. My general mouth feel of the situation was that the position was such that white didn't have the position and material to make a meaningful threat to the black king or the ability to get to a perpetual with the king and the pawn on c2. As long as he sticks near it, he'll find safety. However, I also thought to myself that I didn't have to calculate that because white isn't in a position where a single move could save him. While I saw that Qxh4 was winning, I figured that after Kd7 instead, white had nothing. His only way into the position was attacking c6. If going for b8, I run to d7 and it is over. If he targets c7, he's too late. If he targets c6, Kd7 shuts it down. What does white do with the extra move if they had it? My ideas were Qd4 and we respond with Qxh4 anyway as we'll mate on h1. Alternately, Kh2 to break the pin in which case that messes up Qxh4 but that's not a big deal because we still have Rxh4+. If gxh4, then Qxh4+, Kg1, Qh1++. If instead Kg1, we still have Rh1++. As all these lines seem winning for black, after Rg4, the most likely response is that white realizes that he's losing, plays Qxg4. We play hxg4 and go into a queen and bishop vs 2 rooks endgame with no meaningful open files which shouldn't be a problem. He can never get behind his passed h pawn as long as the bishop stays on the long diagonal. I decided that while I could have probably won faster by retaking the queen with the bishop instead, after f3 he'd at least be able to get his king active and open up some lines whereas if things remain closed, I can see slow wins for black but no feasible plan for victory for white.
This is a very good theme which is a variation of "Guess the ELO" . However IMO the ratings are a bit overrated. No way this is anywhere close to 2700. But I suppose to maneuver the pieces to get to that position and spot the opportunity is what differentiates the lesser players vs the best. Also there is another variable:Time taken to spot the variations(How much time does a 2500+ player take to spot those moves in a real game?) . I hope you will keep up this theme as it is very encouraging for beginners and middle ELO levels.
I found the variation of winning with least casualties... Bishop takes knight at F3, opponent responds with Queen takes Rook at B4 which is a good move but irrelevant then Rook goes to G8 pinning the pawn at G2 so it can't take the bishop then Queen goes to C5 trying to grab the pawn and give check, we respond with King to D7 protecting all pawns then opponent does not have any good moves except moving the G2 pawn one square then finally Queen comes to take the H8 pawn and deliver the checkmate afterwards
0:18 You shouldn't have said this: "Feel free to think about it, *or I'll just give you a couple seconds to think about it* while I'm talking." This suggested that the assignment is to think about the problem for a couple seconds, and then based on what you see in the position in that short time, your level is evaluated. You should be clear about the assignment.
I found the solution with RG5, but I feel it is different if I know there is some sort of solution. On my own I probably would not have calculated out so far. Chess puzzles are great for tactical challenges, but it is the attacking theory that you bring that I really love. You teach the way to think.
I'm 1600-1800 and I saw all of that in about 5-10 minutes. Rg4 was hard to find, but I knew I needed to deflect or block the queen. I looked at Qb7, rather than Qc5 for the perpetual. I also looked at King moves as an alternative to g3. Rg4 worked for those as well. I used to play tournament chess at 1800-1900 and that is at the upper limit of things that would be spotted in a game. Knowing that a combination must be there makes a big difference.
I’m gonna be 100% honest, I noticed every move except moving rook to g4. I figured it could stay on g1 and still have the same effect of pinning the pawn to the king and giving force mate in 3 with queen to f4. My only problem is getting to this stage in the game.
30 years ago I was rated at 2000, haven't played much since due to work and family commitments. As far as I am concerned this type of position is very easy because it is nothing more than a series of standard tricks and crucially unlike in a real game we know that black probably has a forcing win. I solved it as follows 1.Whilst I noted that the b4 rook was under attack, I first looked at forcing moves - after all black is supposed to be able to force a win here. Bxf3 is obvious, and the first move I looked at, as is the fact that gxf3 will lead to forced mate I barely calculated that. 2 So the only possible forcing line has to be 1...Bxf3, 2 Qxb4 Rg8 3 g3. It should be obvious that black needs to play Qxh4 but that black cannot do so until the Qb4 is either blocked or diverted from protecting h4. 3. I tried all possible pawn moves to divert the white Queen but a5 & c5 run into Qf4 and d4 does do anything likewise moving queen or king does not force white to do anything so the only possible forcing move is Rg4 and at that point I stopped my analysis because it was clear to me that white could never force a perpetual and Qxh4 was only stoppable by white playing Qxg4 which leads to a game of 2 rooks versus Queen and bishop which should be winning (I admit I did not do any calculations to prove it). Personally I think the puzzle is more like an 1900-2100 level puzzle. The really hard puzzles are the ones that in the middle of the combination there is a quiet move that does appear to force anything but 2 moves later is a killer - those are 2500+ level puzzles
This was very interesting. I am not a very high level player but I did pretty well on this one. I immediately saw the rook was hanging but I saw Bxf3 followed by Rg8 but then didnt consider Rg4 to kick the queen. However as soon as you showed it I was like ohh nice now you have Qxg4 and then was surprised when you played Rxg4 instead.
I thought the same thing! Except I missed Rg4 attacking the queen... I still think I'm at somewhere around 2300 though. (My actual rating is about 1700.)
What's interesting is that I've noticed quite a few of the lower to mid level ratings myself, except that I tried to use them all together. First things first, opponent is a pawn up. However, the board is almost full, so no decisive advantage here. Yes, I spotted that the Rook is hanging, and that I should probably defend it or move it back before proceeding to my attack. Now, the first moves I noticed were Rb8, Qb8, and Qe7; but then I realised that Rb6 is even better (I'll come to the why part soon; actually, c5 was also an option, but I didn't think of it. But that won't be great either since white can just play a3 and attack the rook). So, my first move: Rb6 Now that it's not hanging anymore, time to attack after opponent's move. Now, possible options for white are to move their knight or their queen, since their rooks aren't really going to be active anyway, and they will need at least 2 pawn moves to attack the rook; so that's unlikely. As for the knight, Nd4 and Ng5 are the 2 options. Let's consider Nd4 first (which is not really a good move anymore). Well, before coming to Black's reply, let's think of White's longer term plan; after Nd4, where will the knight go next? It will be captured everywhere. (Here's why Rb6 was my first choice; it not only moves the rook back but also defends the pawn at c6. If I had played Rb8, Qb8, or Qe7 instead, Nc6 would have forked the king and rook. But it can't anymore). So basically, Nd4 is now a useless move for black, and gives me an extra move for free. Now, before I move on to quite a solid option Ng5, let's first go through what could possibly be done if white just played random moves (well, any queen moves by white are random now, since all my pieces are defended, and he can't check my king without any captures). My plan would be Rg8, followed by bishop takes knight, taking advantage of the pin; and then queen takes their h pawn (which will work even if they had played g3, again due the pin). With a rook, bishop, and queen; it will be a mate quite quickly; if they try Qd4, then Rg4 is the way to go before capturing on h4 with the queen. However, after watching the video, it's quite clear that Rg8 is unnecessary, and more of a waste of time; bishop takes knight should be played directly, since white capturing the bishop is a forced checkmate. Now coming to the main, and possibly best reply of white; Ng5. I don't really have a completely forcing line here, but my idea is to sacrifice the queen on g5. Once white recaptures with the pawn, we push our h pawn forward. With the pawn defended by the rook, and the bishop being active, a mate is possible in quite a few variations even without promoting. However, I can't find a winning combination in variations where they play f3, attacking the bishop and blocking that diagonal. Example: Rb6 Ng5 Qxg5 gx5 h4 g3 gx3 f3 After this (and another similar variation or 2), it seems I'm stuck; in any case if anyone finds a winning move from here, please let me know. Btw, thanks for reading along upto this point; I was also trying to save the rook along with everything else (irony that I ended up sacrificing a queen instead😅)
Extremely instructional. One of my biggest challenges is hone my thought process and get some sense as to the level of analysis necessary to keep improving. This video gave me that perspective. You have a unique talent to clearly communicate these concepts. It gives me more passion to improve my game, even at the age of 72!
Great puzzle! I haven’t played chess in 3 years and still found the 1800 move pretty easily. The chess scene has certainly changed a ton, especially with a new champion coming soon. I remember watching agadmator every day after school with my brother.
4:50 Here you could checkmate in two moves : Queen to h4 (WHITE g3 PAWN is pinned by your rook at g4) White lays his king down or play whatever he want. Queen to h1 - Checkmate :)
more please - not like 'white to move and mate in two' but like this where you explain how each variation reflects our understanding of the game. I knew the rook was under threat, i saw that whites pawn could step to g3 and i saw that rook to g8 locked that pawn down... but i started my attack with the queen and figured i could work it out from there.... 1400 on a good day lol! Thanks.
Yup, got stuck at the 1800 move. I didn't think of moving the rook up because I thought white would just sacrifice their queen for the rook. That's two rooks for a queen, but it also seems to shut down black's attack. Still don't see why white wouldn't/can't just do that. Edit: Looking into it more, stockfish seems to like the queen sac too. Uh, did you make a mistake?
Queen sac is the best move in that position as it doesn't lead directly to a checkmate, but at that point black is just in a winning position. A queen and a bishop vs 2 rooks. The puzzle doesn't use this variation because it would end right at taking the queen. Perhaps he should have mentioned it as the best move for white there, but it doesn't change the moves you make as black.
I saw the white defense with G3, but i thought Qh4 was winning. Didn't remember that white queen after taking the rook was defending h4. Seeing the board after g3, the move rook to g4 comes naturally. But see this in advance is really hard. Really nice video !!!
I calculated to a 2700 level, which I find strange seeing as I'm a 1300 rated player. The puzzle was very interesting though so I'm definately subscribing.
I am exactly the same, I think it ends up being whether or not at our level we’ll be confident enough to make the correct moves in an actual game, or if it’s better to just stay simple and defend an attacked piece. It’s definitely a lot easier to do puzzles as opposed to playing the best moves in a real game.
same i got 2700 except i didnt plan for the attack of the queen on the pawn (i thought him attacking the bishop after taking the rook was better) and i'm 1000 rapid. The fact we know there is a solution help too much i think
Same here where I am like 1000-1300 online as I haven't played much there and I managed to calculate the whole thing to 2700, definitely knowing there is a win helps to find it although I am 2300 in puzzles
You missed a move. The Bishop takes the G2 pawn. King takes bishop. Rook place King in check. King moves. The Black Queen takes pawn on H4. In this position it’s checkmate in two.
The thing that prevents me from going deeper than the 1600 line is basically i just go "ok, that's good enough. Let's see what he plays first", and then I'll start calculating from the new position. Because previously i lost many games on time, so i dont want to spend too much time on each move
It's probably not accurate for blitz or bullet players. I wish it was though. According to this puzzle, despite only calculating for 30 seconds, I should be 1800. But my blitz and bullet ratings are horrible, under 300. Rapid, I'm like 600 or 700 but haven't played many games.
I am literally 1200 and I have found the 2300 variation, overlooked the checks, but found the pin on the pawn leading to the fastest checkamate at the 2700 level. It is really not that hard, I think that these variations are possible to be calculated by lower rated players aswell
@@Skorpien. Ye, I can see some of these variations in like 10 min game but in blitz games you don’t really have time to think it thru this well, so i often make calculations mistakes
4.47 the meaningful and best move in my mind is bishop e4,blocking the queen.Then you take h4 with your queen and white cant take back....Also your rook is saved.
1600elo: if queen takes b4 then you can play bishop g2 attacking the rook, so king has to take, and after king takes g2 black plays rook g8 check, king runs to the corner and Queen takes h4 checkmate
My rating is around 1800 to 1900 in rapid and I've got to say this puzzle was really fun with a lot of hidden insights. I've solved it up to the 2300 range and completely missed Qc5, but I did find Qxh4 after Rg4 (although I did not even consider Rxh4). I'm currently rated around 2990 in puzzles.
I saw all the 2300 level implications after capturing the knight, but I also completely overlooked the hanging rook. That’s why my rating is 500 higher in rapid than in blitz, I guess. 1130 in 15/10, but 650 in 3/2 😢
1:20 before any spoilers i noticed that my rook was under attack, but i actually was calculating Bxf3, then if they recapture, its checkmate, but a more obvious move is to just capture the rook, then i thought of Bxg2, but i didn't see any checkmate there in the given time.
So, I calculated everything required for 2300 (and also an additional line if white moves the f1 rook and allows Rxg2+ instead of playing g3). I also saw Qxh4 (in fact I never even considered Rxh4 and my whole reason for playing Rg4 was to enable Qxh4). I didn't look at Qc5, but I did look at Qb8+ after Qxh4. For the record, I haven't played in nearly 20 years and my last rating was the old ECF equivalent of about 1850. But I did just complete 7 cycles of the Woodpecker Method earlier today.
Not entirely sure how accurate this is, I've been 1500 for a while and even though I considered the various approaches detailed after the passive defense of the rook, I still went with passively defending the rook by bringing the rook back to the backline. I tend to like waiting for my opponent to make concrete mistakes and that is very likely to be a flaw with my style of play.
First thing 1600 wish attack. Then 1800 calculation, saw attack not really working. Then more positional thinking resulted in 1000 decision(c5, a5, Qe7). But Rg4 is beyond my current calculation skill!!!
i am 1000 elo rn and i saw this variation 1. - c5 2. c4 Bxf3 3. g4 Qxh4+ 4. gxh4 Rg8+ 5. Kh2 Rxh4# but i also saw at move 3 it could go 3. e4 Rg8 4. Qf4 Rxg2+ 5. Kh1 Rg4+ 6. Qxf3 Qxh4+ 7. Qh3 Qxh3# I though this was also interesting. Never considered Ng5 though
I am a 'retired' FM (haven't really trained in this Millennium, haven't played in 15 years) and solved this. Since 1.Bxf3 2.Qxb4 Rg8 3.g3 Rg4 4.Qc5 Qxh4 lead to an easy win for Black, I spend much more time on 3. Rfc1 Rxg2+ 4.Kf1 Rg4 5.Qc5 Qxh4 which is much more interesting, i.e. 6.Qxc6+ Kf8 7.Qc5+ (to protect e3) Kg7 8.Ke1 Rg1+ 9.Kd2 Qxf2+ 10.Kc3 and the game is far from over, so 6... Kd8 (after 6.Qxc6+) and now White has a problem, i.e. 7.Ke1 (7.Qa8+ Kd7 is worse for White) Rg1+ 8.Kd2 Qxf2+ 9.Kc3 Qxe3+ 10.Kb2 Qxe5+ where Black should be winning, but White could simply NOT play 6.Qxc6 but 6.Ke1 (so that the Q still protects e3) and after 6... Rg1+ 7.Kd2 Qxf2+ 8.Kc3 White could still fight on, though I believe Black should be winning, a continuation could be 8.... Rxc1 9.Rxc1 Kd7 and Black simply has two pawns for the exchange, a well protected King and should be winning by simply pushing the h-pawn forward. So what's my rating? ;-) An afterthought: Black could also play (after 6.Ke1) 6.... Rg2 and after 7.Kd2 Qxf2+ 8.Kc3 Kd7 White seems to be even more in trouble than above.
But isn't 1... BxN 2.QxR Rg8 3.Rfc1 met quite effectively by 3... Rg4 with the threat of QxP on h4 and the immediate threat to the Q? 4.QxR BxQ seems like a simple endgame win, though I'd also calculate 4... PxQ if I got there to see if I had a forced mate (saw both but didn't bother to calculate past the first win I saw in that line). 4. Qc5 QxP and can white stop mate?
I surprisingly got full marks, however I also calculated the white queens best move was dropping to b7 as compared to c5. As i think that white can force a draw or queen trade if the queen captures the pawn before the king moves to c8
1300 I kinda like: find good move, check flaw, check other move, if better move then check flaw, check which one is better and play, repeat on the next move the problem is the time ofc
Qxg4 instead of Qc5 seems a better move. Yes white trades her queen for a rook, but from there black has no option of advancing her queen thus the situation is open again without a clear winner. I'm confused that neither you nor someone in the comments mentions this. Am I missing something?
As a 650 ratied player I found rook to g8, as whites queen will probably take my rook, i can sweep and take the knight whilst setting up a windmill. Only miscalculation i made was that the queen left the .2 file, so that was kinda sad.
I found rg8 and after putting it in the engine, after knight blocks you’re -5 so its not a bad move, i also spotted the bishop move but couldn’t find the rook move after the pawn move to g3, however i’m only rated 1300 but i have a puzzle rating of 1800-ish, however after seeing the rook move i did see that the best move would be sacrificing the queen so the white rook can move and get the king out of the way Best line according to lichess analysis : Bxf3 2. Qxb4 Rg8 3. g3 Rg4 4. Qxg4 hxg4 5. Rb1 Kd7 6. Kf1 Qh8 (depth average of 22) -11.8 eval stockfish 11+ HCE
I agree with Joni Durana, I am an 1850 player and I solved this to the 2700 level. It is not accurate because you have to get to this point to start with. And as with all puzzles they are easier because you "know " there is a solution.
I spotted a rating of 2700 and actually and can't believed it because I really started to play and practice chess this year. So I hope that one day I will achieve this rating.
Pretty acurate for me. I have questions - 1. I have thought that visualization was very important to become a good chess player. But I don't see much teaching on how to improve visualization. Is it something you are born with and either have or don't have or can it be improved ? 2. This is related to number 1 - when evaluating options I soon forget where I was or what my answer was for a certain option and I have to do it over again. So is there a way to improve memory in this case?
I'm almost 1300 and saw the 1800 tactic but dismissed it as a losing endgame. I thought any attacking plan was thwarted by the queen seeing h4 and saw g3 and thought it was just over with a losing endgame. Ultimately in a game I think I'd probably play the 1000 option of defending the rook because I saw some simpler yet powerful ways to put pressure on white with moves like the capture on f3 delayed, Rg8, etc and think it would be easier to play from the standpoint of not having the queen on b5 but of course not super accurate.
Wait what about rxb3 sacrificing the rook and after cxb3 or axb3 you can capture the knight with bxf3 and if gxf3 rg8+ kh1 or kh2, qh4 is checkmate. And if white doesn't play gxf3 amd plays g3, we still have rg8 followed by qxh4 because g3 would be pinned. I calculated all this being a 1600 and rxb3 didn't even got discussed.
Calculated up to g3 but thought Rc1 instead would be a trickier line for black to figure out after Rxg2+ and the king runs to the right side of the board. Especially is black is running up against time trouble. g3 is also only the best defense if white sacks the queen on g4 for the rook. So that line showed here is not forced. Either way it’s all still winning for black.
Nice puzzle .. but I see a flaw in your analysis: after rook to g4 an alternative is that the attacked white queen can capture the rook on g4. White then loses the queen to the bishop but the immediate mating attack is nullified and the position then goes on much longer. Should still be a win for black but tricky and seems to require going to an end game and needing very precise play by black. I ended up setting this up for analysis by rybka with it playing both sides (only running on my laptop though) and it took it's time but eventually found a rather laborious win for black.
Yeah, this is why I got stuck at "1800". Material wise it would be fine (2 rooks for 1 queen) and it completely shut down the attack. I double checked with stockfish to see what I was missing only for stockfish to agree with me.
I spotted the variation Rook to G4, white queen takes, Bishop can retake but black's attack is over. I didn't find mate for either side in the next 10 moves so I'm not sure who wins from that position. Sac'ing the Queen is the way out for white though.
Actually very good, I'm a 1400ish player and got pretty close to the 1800 answer. However, my take was to open up the king by taking the pawn in order to avoid g3, and if king takes then rook and queen could bomb it, and if he ignored I could trade it for a rook, leading to loss of rook and bishop vs winning rook and pawn while opening the king. However that line fails since the queen can't contribute to the attack because in order for it to work Rg4 is required and it wouldn't work. So yeah, I got up to 1600 just fine, but failed in the follow up.
I found the level of 1600 elo pretty quickly, and I found he didn't have to take but I couldn't look further. Yet I'm 450 elo, and pretty stuck there. :/
I started playing Chess this week and have a rating of 230 or something and got the 1600 solution. It’s so cool to see all the different ways to solve things.
4:20 I completely missed that the queen could take in my head! I was imagining that the bishop was still there in my calculations, so I just took the pawn with my queen. We'll get 'em next time! I think something went wrong in my calculations with Qxb4, because in my mind that was an optional move because it didn't adress the attack at all(I was wrong), so because I didn't think it would affect the game, I completely ignored it, when I shouldn't've. I was completly bind to this move for a while until 7:20! Conclusion: Spend more time considering intercepting pieces, and when a piece moves/is revealed to get more squares, i.e. a reveal attack, to make sure I know where all the peices are moving. What are your takeaways? Feel free to review with me!
I’m over the moon I’m 1400 and I sometimes get the 1600 move in these puzzles but this time I found Rg4, maybe a little lucky as I know it’s a puzzle I don’t think I’d find that in a game to be fair and I wasted time thinking about Qxh4 stuff and deduced it lost a rook bc of the forcing checks, didn’t notice the queen would’ve been hanging anyway 😂😂 I love these videos I’ve only recently discovered them, the puzzles you choose are great in forcing me to think both tactically and strategically and I love how you explain at every level how to think in order to improve to the next level
Im 1700 fide and I solved it. It took me like 10 minutes because there are many options, but after Bxf3 I think the line is very forced and it is not really difficult to calculate it, you just have to keep calculating deeper and deeper until checkmate
Well according to this I got somewhere between about 1800 and 2000, but my actual rating is closer to 1000. The puzzle ranking comes from people playing the puzzle, and the puzzle rank is traded off the player rank depending on if you or the puzzle wins, much like the ELO of two players.
I’m 1100 and say the 2700 variation and was shocked when you didn’t say Queen takes right away, I did spend like 4minutes calculating it though as I really wanted to find the answer, my first instinct told me to take the knight with the bishop and saw the 1600 variation right away. I feel like it’s a lot easier to solve these when you know it’s a puzzle, lots of my chess positions are losing and I don’t think to solve it like a puzzle lol

1800 I completely didn't notice that the rook was hanging so guess I failed my rating level, but at the same time I do very often notice such things in games.
I saw 1... Bxf3, 2. Qxb4 ... Rg8 3. g3 but rejected 3... Rg4 because of 4. Qxg4, and I can't see an immediate win for black. Instead, I proposed 3... Be4 cutting the queen off from the kingside and threatening 4... Qxh4. If now, 4. f3 then 4... Rxg3, 5. Kf2... Rxf3, 4. Ke2 (4. Ke1 ... Qxh4, 5. Kd2 {5. Ke2 ... Rxf1 followed by 6...Bd3} ... Qh2, 6. Ke1 (6. Kc3 ... Qxc2, 7. Kd4 ...c5) ... Rxf1, 7. Kxf1 ... Qh1. If instead, 4. Kh2 then now 4... Rg4 threatening 5 ... Rxh4. Now 6. Kh3 is not possible due to 6 ...Bg2. This wasn't the solution, but, since I am an average club player, I may have missed other candidate moves for white after 3 ... Be4. Nonetheless it was enjoyable trying to calculate variations in such positions using methods from another RCA course (Calculate til mate). Please provide more videos like this as they help me develop my chess.
i want learn end game
Bishop should cut the knight
2600 I guess
Spotted the 1600 level and that your opponent didn’t have to take back but completely overlooked the castle capture! Which is why I blunder so much.
same
Me too
Same, but the people my level would really just take my bishop with the pawn anyways lol
Same for me, I assumed the opponent would recapture the bishop and I could get the checkmate right away.
It's strange that I didn't even notice that my rook was vulnerable.
I would really like to see more of these puzzles. It looks like a very good way to improve your game.
If you took the knight with the bishop KNOWING YOUR ROOK ID HANGING then ur 1600 however, in your case you had no clue your rook was hanging making you 800 rated as he mentioned before...
One problem i find with puzzles is, that you just know theres something good in that certain position, so you kind of eliminate all the ''boring'' moves that dont do anything in the first place. In a normal game u might not see the forcing line, because you dont know theres something concrete on the board. I like those kind of videos though, please do more.
That's the issue I had as well. I was immediately able to write off defending my rook, because this puzzle was so, so blatantly forcing Oh No My Rook checkmate variations. It didn't take me very long to find that White has very few defensive options, relying on that powerful b4 defense and check threats to try and slow down your attack.
However, I got stuck on g3 rg4, because that was the point where I was unable to find white's best move according to this video and didn't see a checkmate line.
Using chess classroom I followed the line further, and white's best move is actually to sacrifice on qxg4, preventing the checkmate threat but leaving a bishop queen vs double rook endgame.
Now I'm not claiming I'm some kind of genius, I wasn't able to distinguish whether or not I was on the right track past bxf3 until using stockfish and watching the video, so while I'm happy with the 1600 rating this video would give me, I still find it very funny that stockfish disagrees with RCA about the strongest variation for white.
Indeed. However for this particular puzzle, you might eliminate good moves too early like Bxc6， because they looked suspiciously obvious. You would think 2000+ players would make very unusual first moves probably with a huge sacrifice. In real games, Bxc6 will be played out more easily, even most may have never calculated its most tricky variations.
On the other hand, solving puzzles can actually make you constantly seek attacking opportunities in real games. You will become much more aggressive and sharp.
the whole point of doing puzzles is so you develop your pattern recognition, so that while in a game you go "oh wait, there's gotta be a tactic here".
And I mean, you should always try not to make "a move that doesn't do anything in the first place" when you are playing XD
yeah, I somehow calculated Bxf3 2. gxf3 Rg8+ 3. Kh1 Qh4# or Rh4# in some seconds and meanwhile I am a 900 elo player.
Yes, that is always problem with puzzles. I was able to quickly find Rb4 and Qxa4 variation and that white queen will be out of play and without perpetual after Kb7, but I have never reached above 2100.
Super accurate actually. I’m 1600ish and got the 1600 rating. I definitely quit calculating and just said, “it’ll work out” after 3 moves
Haha...
I got the 1600 rating on this test. But, I am not even a chess player. I have no rate, and I think my game level is worse than mine while doing puzzles.
@@Normal_user_coniven interesting! I’m not sure what that might imply
I am 800 and I saw the 1600 and almost found the 2300
Lol same I was like "there's probably a mate there somehow"
I'm 600 and got 1800 raiting xD
7:48 I did calculate upto this level but there is no way on the face of this earth that I’m 2600. If I’m 2600, then my brother who beats me on a regular basis is Magnus.
lol i got 2700 and meanwhile im only 1600
So here is what is strange. I actually calculated all the way TO the Qxh4 variation! But I totally missed the fact that my rook was hanging. As it turns out, it didn't matter -- but I'm not sure if my rating is 2700 or 800. 🙂 Very fun and practical puzzle!
Same
Same that attack looked to promising 😂
How can you calculate the variation where queen literally takes the rook but say that you missed that rook was hanging?
you are looking at only half the board, so 800.

08:10 How to calculate variations in the middlegame?
I enjoyed your analysis :)
It’s important to mention that puzzle ratings aren’t so close to ELO. Mine’s 1650 and 2850 so you can see the difference.
Ha 2100 vs 650
The puzzle rather evaluates your middlegame skills. If your endgame skills or opening knowledge is lacking, it won't show it. Still, the test makes a lot of sense.
yea, i solved the 1600 puzzle, but my elo is 1000
well i'am 1742 but got the 2300.

@@GMIgorSmirnov Im a 221 elo rated player and also found the 1600 level variation but lets be honest here it was probably just luck
Yes! More "what's my level" challenges. Fun and interesting!
Alright, I'll prepare some more of those soon
I liked it too and I also liked the explanation of how differently rated people think. In a relatively short video. Very well made!
I'm 800 rated and my first through was the 1600 move, but I legitimately didn't even notice my rook was hanging so...
Same for me.
I hope the puzzle also somewhat shows the way for you to progress further (by adopting more advanced ways of thinking and calculating).
Same!

Thanks for your feedback! I will.
I've only seen a couple of vids, but I have a gut feeling this has the potential to be more useful for higher-rated players than Gotham chess, despite the popularity.
@@angerventing2694 - Can not agree more.
@@GMIgorSmirnov I thought best move afterrook g4 was QG4 because it stops the mate atleast for now
More chess puzzles like this one are always appreciated. Chess games at the grandmaster level which did not result in a draw, are always good as a learning tool.
As an 1800 player, after visualizing Bxf3 Qxb4 Rb8 g3 i really went "Nah this ain't working" and went for the overwhelmingly less calculated Rg8.
After that Qxg4
I found another variation: Black takes knight, white queen takes rook, Black Bishop takes the pawn that didnt strike back from earlier, white takes black bishop, Black rook comes to g8 (giving a check), white king to 1h (there arent any other moves) and the black queen takes pawn at 4h giving checkmate. Now please respond to this cuz I spent much time and I really wanna know my rating (I cant think this clearly during games). 😢
you should do more of these, but also throw in ones where the best moves are not forcing. in puzzle positions like these you overlook boring moves because you know it’s a puzzle
PuzzLEGO I didn't expect you to be here!!
why did u stop videos
Thanks for your feedback! It's clear you enjoy puzzles 😉
Saw the bishop take, saw the follow up and saw the queen takes. I didn't calculate whites checks with the queen which can sometimes be my downfall. My strength i feel is tactics, weaknesses being moving too fast, not fully calculating, or as you mentioned hoping that an attack works out
Same here. I saw that the pawn was pinned and I could take the pawn with no problem but didn't see the white queens check.
@@bradburns491 similar for me. I saw the pawn would be pinned after rook h2, so white couldn't take the bishop any more after taking the rook. So the attack would go on even after the queen defends the pawn when taking the rook. But I didn't see the defensive move g3.
Exactly the same thing - I found Rg4 as the move that made Qxh4 viable in the first place and then went "eh, the King can run away behind the queen and rook" (though I was thinking of Qb7 and not Qc3-c5 for White).
It is important for us all not to play hope chess, but it gets really easy to when your visualization has to go far and you start feeling doubts.
PS: I am a bit under 1700 FIDE.
@@kaynight64 I thought of the exact same damn thing xD
This is me too right now!
i first thought 1800 level, but after seeing the 2300 move Rg4 (which i have no idea how i missed), i immediately found the 2700 level Qxd4. after seeing the board im ok at calculating but im absolutely horrible at visualizing the board after 3 or so moves since i get easily confused
Obviously if you don't spot the intermediary steps, you cannot claim the to understand the highest level moves. Because if you blunder before that, you wouldn't reach that position anyway.
Missed Rg4 initially but once you see.. Then qa4 looked easy..
I have thought that visualization was very important to become a good chess player. But I don't see much teaching on how to improve visualization. Is it something you are born with and either have or don't have or can it be improved ?
@@lw216316 there are 2 things here.. One is direct visualization based on the position.. It's not that difficult.. But when you start making moves in your head and visualize them, it's different thing all together...
@@AP-eb8hd yes, its the 'in your head" the imagination part - is that a quality a person is born with or can improve, is so how do you do that in chess?
According to this, I'm 1600 and something. Now I just need to find where those 600+ points are hidden in me
What I learned form this puzzle is that I see most of the components of the problem, but I short-change the calculations when I see a move that is clearly favorable.
I also chose bishop takes & totally overlooked the queen threatening the castle. I seem to be hanging in the area of 750-850 in rapid and 1325-1450 for puzzles (hard level). I was taught to play (basics) chess but only now in middle adulthood started to look into chess in a more (I do have an insatiable need to play daily to get my fix) academic sense and seem to have a real addiction to it since moving my first pawn inJanuary 2023. I would love to join some chess club in South East Michigan at some point with aspirations of continual growth & study. Shooting for a 1600 ELO for an initial goal. I ❤ the video.
For newer players, try playing slower games and try to calculate 2 moves for every "power" piece. Eventually you start getting a feel for things and just start to see the threat without looking for it which you should just use to read deeper.
Pawns I feel are pretty instinctual most of the time for even newer players already, but lots of people miss forks or a surprise take.
I didn't even consider the moves at 2600 because I saw queen h4.
Calculated everything up to failing to find Rg4. As a result, went back and thought, okay, Bxf3 works as long as I avoid Qxb4 because it defends h4. So I thought c5 (1000 rating) or Qe7 (not mentioned) would allow Bxf3 on the next move. This meant calculating Ng5, when Bxg2 is either a free pawn or white runs into Kxg2 Rxh4 (which either wins or exchanges down until you're 2-3 pawns up depending on how white plays - white has e4 to defend with the queen and the king can try escape via f3). Of course, c5 is met with Qe2... While an 1800 might find Rg4 in the "think" after g3, it's hard to say an 1800 would have chosen this line other than by "hoping it works out", which you don't recommend doing. As such, I chose Qe7 because Qc5 looked more promising after white's Qe2 than c5.
So, what's my rating?
This was awesome! I just found this channel yesterday. I usually watch Hikaru but your videos are more like classroom math exercises. I like how organized and concise, while still being thorough, they are. I am around 800 elo, and you’re right that I did hang my rook, but upon noticing I was able to calculate the refutation of bishop takes knight (queen takes rook) and then up to white playing g3 and I thought the attack was over. I didn’t see rook to the fourth rank attacking the queen, and while I did consider sacking on g3, I never considered sacking on h4 or anything else. I will keep improving!
👍
I calculated everything except the king running away which I did a little differently. My general mouth feel of the situation was that the position was such that white didn't have the position and material to make a meaningful threat to the black king or the ability to get to a perpetual with the king and the pawn on c2. As long as he sticks near it, he'll find safety. However, I also thought to myself that I didn't have to calculate that because white isn't in a position where a single move could save him. While I saw that Qxh4 was winning, I figured that after Kd7 instead, white had nothing. His only way into the position was attacking c6. If going for b8, I run to d7 and it is over. If he targets c7, he's too late. If he targets c6, Kd7 shuts it down. What does white do with the extra move if they had it? My ideas were Qd4 and we respond with Qxh4 anyway as we'll mate on h1. Alternately, Kh2 to break the pin in which case that messes up Qxh4 but that's not a big deal because we still have Rxh4+. If gxh4, then Qxh4+, Kg1, Qh1++. If instead Kg1, we still have Rh1++. As all these lines seem winning for black, after Rg4, the most likely response is that white realizes that he's losing, plays Qxg4. We play hxg4 and go into a queen and bishop vs 2 rooks endgame with no meaningful open files which shouldn't be a problem. He can never get behind his passed h pawn as long as the bishop stays on the long diagonal. I decided that while I could have probably won faster by retaking the queen with the bishop instead, after f3 he'd at least be able to get his king active and open up some lines whereas if things remain closed, I can see slow wins for black but no feasible plan for victory for white.
This is a very good theme which is a variation of "Guess the ELO" . However IMO the ratings are a bit overrated. No way this is anywhere close to 2700. But I suppose to maneuver the pieces to get to that position and spot the opportunity is what differentiates the lesser players vs the best. Also there is another variable:Time taken to spot the variations(How much time does a 2500+ player take to spot those moves in a real game?) . I hope you will keep up this theme as it is very encouraging for beginners and middle ELO levels.
I think it's just about calculation ability
Love your content Igor! Entertaining but so educational, explained in a very easy to understand format. Thanks 🙏🏼
I found the variation of winning with least casualties... Bishop takes knight at F3, opponent responds with Queen takes Rook at B4 which is a good move but irrelevant then Rook goes to G8 pinning the pawn at G2 so it can't take the bishop then Queen goes to C5 trying to grab the pawn and give check, we respond with King to D7 protecting all pawns then opponent does not have any good moves except moving the G2 pawn one square then finally Queen comes to take the H8 pawn and deliver the checkmate afterwards
0:18 You shouldn't have said this: "Feel free to think about it, *or I'll just give you a couple seconds to think about it* while I'm talking." This suggested that the assignment is to think about the problem for a couple seconds, and then based on what you see in the position in that short time, your level is evaluated. You should be clear about the assignment.
i got 1600 in like 3 seconds when i saw that puzzle (im 800 rating💀💀)
Same
I got 1600 even though my game rating is 350 and my puzzle rating is 950
Yeah, I would love to see more videos like this. it's a brilliant format
I found the solution with RG5, but I feel it is different if I know there is some sort of solution. On my own I probably would not have calculated out so far. Chess puzzles are great for tactical challenges, but it is the attacking theory that you bring that I really love. You teach the way to think.
That's a great result anyway! 👍
I'm 1600-1800 and I saw all of that in about 5-10 minutes. Rg4 was hard to find, but I knew I needed to deflect or block the queen. I looked at Qb7, rather than Qc5 for the perpetual. I also looked at King moves as an alternative to g3. Rg4 worked for those as well. I used to play tournament chess at 1800-1900 and that is at the upper limit of things that would be spotted in a game. Knowing that a combination must be there makes a big difference.
I’m gonna be 100% honest, I noticed every move except moving rook to g4. I figured it could stay on g1 and still have the same effect of pinning the pawn to the king and giving force mate in 3 with queen to f4. My only problem is getting to this stage in the game.
30 years ago I was rated at 2000, haven't played much since due to work and family commitments. As far as I am concerned this type of position is very easy because it is nothing more than a series of standard tricks and crucially unlike in a real game we know that black probably has a forcing win.
I solved it as follows
1.Whilst I noted that the b4 rook was under attack, I first looked at forcing moves - after all black is supposed to be able to force a win here. Bxf3 is obvious, and the first move I looked at, as is the fact that gxf3 will lead to forced mate I barely calculated that.
2 So the only possible forcing line has to be 1...Bxf3, 2 Qxb4 Rg8 3 g3. It should be obvious that black needs to play Qxh4 but that black cannot do so until the Qb4 is either blocked or diverted from protecting h4.
3. I tried all possible pawn moves to divert the white Queen but a5 & c5 run into Qf4 and d4 does do anything likewise moving queen or king does not force white to do anything so the only possible forcing move is Rg4 and at that point I stopped my analysis because it was clear to me that white could never force a perpetual and Qxh4 was only stoppable by white playing Qxg4 which leads to a game of 2 rooks versus Queen and bishop which should be winning (I admit I did not do any calculations to prove it).
Personally I think the puzzle is more like an 1900-2100 level puzzle. The really hard puzzles are the ones that in the middle of the combination there is a quiet move that does appear to force anything but 2 moves later is a killer - those are 2500+ level puzzles
This was very interesting. I am not a very high level player but I did pretty well on this one. I immediately saw the rook was hanging but I saw Bxf3 followed by Rg8 but then didnt consider Rg4 to kick the queen. However as soon as you showed it I was like ohh nice now you have Qxg4 and then was surprised when you played Rxg4 instead.
That was well done by you!
I thought the same thing! Except I missed Rg4 attacking the queen... I still think I'm at somewhere around 2300 though. (My actual rating is about 1700.)
I am 1800 elo but I saw the 2760 diagram, I think it isnt all about tactic but also about strategy and knowledge of openings and a lot more
yeah, this is more like 2700 elo on puzzles
Wow! Sooooo helpful. Please do more of these kind of videos. Thank you!
🙏
What's interesting is that I've noticed quite a few of the lower to mid level ratings myself, except that I tried to use them all together.
First things first, opponent is a pawn up. However, the board is almost full, so no decisive advantage here.
Yes, I spotted that the Rook is hanging, and that I should probably defend it or move it back before proceeding to my attack. Now, the first moves I noticed were Rb8, Qb8, and Qe7; but then I realised that Rb6 is even better (I'll come to the why part soon; actually, c5 was also an option, but I didn't think of it. But that won't be great either since white can just play a3 and attack the rook).
So, my first move: Rb6
Now that it's not hanging anymore, time to attack after opponent's move.
Now, possible options for white are to move their knight or their queen, since their rooks aren't really going to be active anyway, and they will need at least 2 pawn moves to attack the rook; so that's unlikely. As for the knight, Nd4 and Ng5 are the 2 options. Let's consider Nd4 first (which is not really a good move anymore).
Well, before coming to Black's reply, let's think of White's longer term plan; after Nd4, where will the knight go next? It will be captured everywhere. (Here's why Rb6 was my first choice; it not only moves the rook back but also defends the pawn at c6. If I had played Rb8, Qb8, or Qe7 instead, Nc6 would have forked the king and rook. But it can't anymore).
So basically, Nd4 is now a useless move for black, and gives me an extra move for free. Now, before I move on to quite a solid option Ng5, let's first go through what could possibly be done if white just played random moves (well, any queen moves by white are random now, since all my pieces are defended, and he can't check my king without any captures). My plan would be Rg8, followed by bishop takes knight, taking advantage of the pin; and then queen takes their h pawn (which will work even if they had played g3, again due the pin). With a rook, bishop, and queen; it will be a mate quite quickly; if they try Qd4, then Rg4 is the way to go before capturing on h4 with the queen. However, after watching the video, it's quite clear that Rg8 is unnecessary, and more of a waste of time; bishop takes knight should be played directly, since white capturing the bishop is a forced checkmate.
Now coming to the main, and possibly best reply of white; Ng5. I don't really have a completely forcing line here, but my idea is to sacrifice the queen on g5. Once white recaptures with the pawn, we push our h pawn forward. With the pawn defended by the rook, and the bishop being active, a mate is possible in quite a few variations even without promoting. However, I can't find a winning combination in variations where they play f3, attacking the bishop and blocking that diagonal. Example:
Rb6
Ng5 Qxg5
gx5 h4
g3 gx3
f3
After this (and another similar variation or 2), it seems I'm stuck; in any case if anyone finds a winning move from here, please let me know. Btw, thanks for reading along upto this point; I was also trying to save the rook along with everything else (irony that I ended up sacrificing a queen instead😅)
Bro was written an essay for exams 💀💀
Extremely instructional. One of my biggest challenges is hone my thought process and get some sense as to the level of analysis necessary to keep improving. This video gave me that perspective. You have a unique talent to clearly communicate these concepts. It gives me more passion to improve my game, even at the age of 72!
Excellent!
Thanks for this Igor, can we PLEASE have some more like this, it's a fun way of finding our new potential rating 👍
Great puzzle! I haven’t played chess in 3 years and still found the 1800 move pretty easily. The chess scene has certainly changed a ton, especially with a new champion coming soon. I remember watching agadmator every day after school with my brother.
GothamChess speaks for himself.
You are a great teacher Igor. Thank you.
4:50 Here you could checkmate in two moves :
Queen to h4 (WHITE g3 PAWN is pinned by your rook at g4)
White lays his king down or play whatever he want.
Queen to h1 - Checkmate :)
hahahahahah i should have finished watching the video :p
more please - not like 'white to move and mate in two' but like this where you explain how each variation reflects our understanding of the game. I knew the rook was under threat, i saw that whites pawn could step to g3 and i saw that rook to g8 locked that pawn down... but i started my attack with the queen and figured i could work it out from there.... 1400 on a good day lol! Thanks.
Yup, got stuck at the 1800 move.
I didn't think of moving the rook up because I thought white would just sacrifice their queen for the rook. That's two rooks for a queen, but it also seems to shut down black's attack. Still don't see why white wouldn't/can't just do that.
Edit: Looking into it more, stockfish seems to like the queen sac too. Uh, did you make a mistake?
Queen sac is the best move in that position as it doesn't lead directly to a checkmate, but at that point black is just in a winning position. A queen and a bishop vs 2 rooks. The puzzle doesn't use this variation because it would end right at taking the queen. Perhaps he should have mentioned it as the best move for white there, but it doesn't change the moves you make as black.
It doesn't matter it's the best move, what matters is that from that point white is obviously winning without any need to calculate further
Even tho you have the 2 rooks for the queen white is not able to stop Ke7 Qh8 and Qh1 mate
I saw the white defense with G3, but i thought Qh4 was winning. Didn't remember that white queen after taking the rook was defending h4. Seeing the board after g3, the move rook to g4 comes naturally. But see this in advance is really hard. Really nice video !!!
Same. Lateral queen captures are tough to see sometimes somehow.
I'm glad it was helpful!
I calculated to a 2700 level, which I find strange seeing as I'm a 1300 rated player. The puzzle was very interesting though so I'm definately subscribing.
I am exactly the same, I think it ends up being whether or not at our level we’ll be confident enough to make the correct moves in an actual game, or if it’s better to just stay simple and defend an attacked piece. It’s definitely a lot easier to do puzzles as opposed to playing the best moves in a real game.
same i got 2700 except i didnt plan for the attack of the queen on the pawn (i thought him attacking the bishop after taking the rook was better) and i'm 1000 rapid. The fact we know there is a solution help too much i think
Same here where I am like 1000-1300 online as I haven't played much there and I managed to calculate the whole thing to 2700, definitely knowing there is a win helps to find it although I am 2300 in puzzles
You missed a move. The Bishop takes the G2 pawn. King takes bishop. Rook place King in check. King moves. The Black Queen takes pawn on H4. In this position it’s checkmate in two.
The thing that prevents me from going deeper than the 1600 line is basically i just go "ok, that's good enough. Let's see what he plays first", and then I'll start calculating from the new position. Because previously i lost many games on time, so i dont want to spend too much time on each move
The quiz is well designed indeed. I am 1518 right now. I exactly thought of the move of 1600.
im a little 900 noobie and got to the 1800 calculation. Im not convinced.
I thought of the 1600 move and I'm 600. sadly being 1600 takes more than finding a move in this specific situation
I thought of 1800 and is 1000 this quiz is not really accurate
It's probably not accurate for blitz or bullet players. I wish it was though. According to this puzzle, despite only calculating for 30 seconds, I should be 1800. But my blitz and bullet ratings are horrible, under 300. Rapid, I'm like 600 or 700 but haven't played many games.
@@harbingerofwarx995 yeah same, my blitz win rate is so bad I'm scared of getting banned for sandbagging
I am literally 1200 and I have found the 2300 variation, overlooked the checks, but found the pin on the pawn leading to the fastest checkamate at the 2700 level. It is really not that hard, I think that these variations are possible to be calculated by lower rated players aswell
what is your puzzle rating?
@@theCometPM 2300
Sounds about right ist just hard to spot something like this in a real game. But that how we have to think to actually fin stuff
@@Skorpien. Ye, I can see some of these variations in like 10 min game but in blitz games you don’t really have time to think it thru this well, so i often make calculations mistakes
Really interesting learning video! Thank you Igor. This reminds me in a way of Jeremy Silman's book "Reassess your Chess". Please showcase others 🙂
4.47 the meaningful and best move in my mind is bishop e4,blocking the queen.Then you take h4 with your queen and white cant take back....Also your rook is saved.
1600elo:
if queen takes b4 then you can play bishop g2 attacking the rook, so king has to take, and after king takes g2 black plays rook g8 check, king runs to the corner and Queen takes h4 checkmate
My rating is around 1800 to 1900 in rapid and I've got to say this puzzle was really fun with a lot of hidden insights.
I've solved it up to the 2300 range and completely missed Qc5, but I did find Qxh4 after Rg4 (although I did not even consider Rxh4).
I'm currently rated around 2990 in puzzles.
I saw all the 2300 level implications after capturing the knight, but I also completely overlooked the hanging rook. That’s why my rating is 500 higher in rapid than in blitz, I guess. 1130 in 15/10, but 650 in 3/2 😢
Same here I'm 2300 rated in rapid but only nearly 1800 in blitz
Hmmm
I think my elo is 3
1:20 before any spoilers i noticed that my rook was under attack, but i actually was calculating Bxf3, then if they recapture, its checkmate, but a more obvious move is to just capture the rook, then i thought of Bxg2, but i didn't see any checkmate there in the given time.
So, I calculated everything required for 2300 (and also an additional line if white moves the f1 rook and allows Rxg2+ instead of playing g3). I also saw Qxh4 (in fact I never even considered Rxh4 and my whole reason for playing Rg4 was to enable Qxh4). I didn't look at Qc5, but I did look at Qb8+ after Qxh4.
For the record, I haven't played in nearly 20 years and my last rating was the old ECF equivalent of about 1850. But I did just complete 7 cycles of the Woodpecker Method earlier today.
Not entirely sure how accurate this is, I've been 1500 for a while and even though I considered the various approaches detailed after the passive defense of the rook, I still went with passively defending the rook by bringing the rook back to the backline. I tend to like waiting for my opponent to make concrete mistakes and that is very likely to be a flaw with my style of play.
First thing 1600 wish attack. Then 1800 calculation, saw attack not really working. Then more positional thinking resulted in 1000 decision(c5, a5, Qe7). But Rg4 is beyond my current calculation skill!!!
i am 1000 elo rn and i saw this variation
1. - c5
2. c4 Bxf3
3. g4 Qxh4+
4. gxh4 Rg8+
5. Kh2 Rxh4#
but i also saw at move 3 it could go
3. e4 Rg8
4. Qf4 Rxg2+
5. Kh1 Rg4+
6. Qxf3 Qxh4+
7. Qh3 Qxh3#
I though this was also interesting. Never considered Ng5 though
I think there is a line F3 B4 g8 g3 g4 and then queen g4 should be the best move stopping a checkmate threat (but loosing a queen).
I picked the 1300 solution in 5seconds and said “yup, that’s what I would play in blitz” spot on.
I am a 'retired' FM (haven't really trained in this Millennium, haven't played in 15 years) and solved this. Since 1.Bxf3 2.Qxb4 Rg8 3.g3 Rg4 4.Qc5 Qxh4 lead to an easy win for Black, I spend much more time on 3. Rfc1 Rxg2+ 4.Kf1 Rg4 5.Qc5 Qxh4 which is much more interesting, i.e. 6.Qxc6+ Kf8 7.Qc5+ (to protect e3) Kg7 8.Ke1 Rg1+ 9.Kd2 Qxf2+ 10.Kc3 and the game is far from over, so 6... Kd8 (after 6.Qxc6+) and now White has a problem, i.e. 7.Ke1 (7.Qa8+ Kd7 is worse for White) Rg1+ 8.Kd2 Qxf2+ 9.Kc3 Qxe3+ 10.Kb2 Qxe5+ where Black should be winning, but White could simply NOT play 6.Qxc6 but 6.Ke1 (so that the Q still protects e3) and after 6... Rg1+ 7.Kd2 Qxf2+ 8.Kc3 White could still fight on, though I believe Black should be winning, a continuation could be 8.... Rxc1 9.Rxc1 Kd7 and Black simply has two pawns for the exchange, a well protected King and should be winning by simply pushing the h-pawn forward. So what's my rating? ;-)
An afterthought: Black could also play (after 6.Ke1) 6.... Rg2 and after 7.Kd2 Qxf2+ 8.Kc3 Kd7 White seems to be even more in trouble than above.
But isn't 1... BxN 2.QxR Rg8 3.Rfc1 met quite effectively by 3... Rg4 with the threat of QxP on h4 and the immediate threat to the Q? 4.QxR BxQ seems like a simple endgame win, though I'd also calculate 4... PxQ if I got there to see if I had a forced mate (saw both but didn't bother to calculate past the first win I saw in that line). 4. Qc5 QxP and can white stop mate?
I surprisingly got full marks, however I also calculated the white queens best move was dropping to b7 as compared to c5. As i think that white can force a draw or queen trade if the queen captures the pawn before the king moves to c8
3:18 did exactly that but didn't notice the hanging rook lmao
Same
1300
I kinda like: find good move, check flaw, check other move, if better move then check flaw, check which one is better and play, repeat on the next move
the problem is the time ofc
This puzzle hinges around Rg4 and Qc5 imo. Those two moves are !!
I love this type of video - great format. Thank you!
Very pretty. I have calculated everything right except that on Qc3/c5 I have calculated Kd7 instead of taking on h4 immediately.
My ELO is 900, I calculated Bxf3 and also them not taking, but I completely missed the queen threatening my rook.
Qxg4 instead of Qc5 seems a better move. Yes white trades her queen for a rook, but from there black has no option of advancing her queen thus the situation is open again without a clear winner. I'm confused that neither you nor someone in the comments mentions this. Am I missing something?
As a 650 ratied player I found rook to g8, as whites queen will probably take my rook, i can sweep and take the knight whilst setting up a windmill. Only miscalculation i made was that the queen left the .2 file, so that was kinda sad.
I found rg8 and after putting it in the engine, after knight blocks you’re -5 so its not a bad move, i also spotted the bishop move but couldn’t find the rook move after the pawn move to g3, however i’m only rated 1300 but i have a puzzle rating of 1800-ish, however after seeing the rook move i did see that the best move would be sacrificing the queen so the white rook can move and get the king out of the way
Best line according to lichess analysis : Bxf3 2. Qxb4 Rg8 3. g3 Rg4 4. Qxg4 hxg4 5. Rb1 Kd7 6. Kf1 Qh8 (depth average of 22) -11.8 eval stockfish 11+ HCE
being a 600 in rapid with 1300 on puzzles and getting 1600 on this puzzle makes me that im probably smurfing people in rapid
I agree with Joni Durana, I am an 1850 player and I solved this to the 2700 level. It is not accurate because you have to get to this point to start with. And as with all puzzles they are easier because you "know " there is a solution.
You described me prefectly of seeing up to the 1800 level but not really being able to see how to continue.
I spotted a rating of 2700 and actually and can't believed it because I really started to play and practice chess this year. So I hope that one day I will achieve this rating.
Pretty acurate for me. I have questions -
1. I have thought that visualization was very important to become a good chess player. But I don't see much teaching on how to improve visualization. Is it something you are born with and either have or don't have or can it be improved ?
2. This is related to number 1 - when evaluating options I soon forget where I was or what my answer was for a certain option and I have to do it over again. So is there a way to improve memory in this case?
I'm almost 1300 and saw the 1800 tactic but dismissed it as a losing endgame. I thought any attacking plan was thwarted by the queen seeing h4 and saw g3 and thought it was just over with a losing endgame. Ultimately in a game I think I'd probably play the 1000 option of defending the rook because I saw some simpler yet powerful ways to put pressure on white with moves like the capture on f3 delayed, Rg8, etc and think it would be easier to play from the standpoint of not having the queen on b5 but of course not super accurate.
Wait what about rxb3 sacrificing the rook and after cxb3 or axb3 you can capture the knight with bxf3 and if gxf3 rg8+ kh1 or kh2, qh4 is checkmate. And if white doesn't play gxf3 amd plays g3, we still have rg8 followed by qxh4 because g3 would be pinned. I calculated all this being a 1600 and rxb3 didn't even got discussed.
Calculated up to g3 but thought Rc1 instead would be a trickier line for black to figure out after Rxg2+ and the king runs to the right side of the board. Especially is black is running up against time trouble. g3 is also only the best defense if white sacks the queen on g4 for the rook. So that line showed here is not forced.
Either way it’s all still winning for black.
damn, i found the 1800 tactic and the 2600 followups as a 900
Nice puzzle .. but I see a flaw in your analysis: after rook to g4 an alternative is that the attacked white queen can capture the rook on g4. White then loses the queen to the bishop but the immediate mating attack is nullified and the position then goes on much longer. Should still be a win for black but tricky and seems to require going to an end game and needing very precise play by black. I ended up setting this up for analysis by rybka with it playing both sides (only running on my laptop though) and it took it's time but eventually found a rather laborious win for black.
Yeah, this is why I got stuck at "1800". Material wise it would be fine (2 rooks for 1 queen) and it completely shut down the attack.
I double checked with stockfish to see what I was missing only for stockfish to agree with me.
There is a problem, I am 2200 on lichess and I solved this puzzle perfectly 😂
I spotted the variation Rook to G4, white queen takes, Bishop can retake but black's attack is over. I didn't find mate for either side in the next 10 moves so I'm not sure who wins from that position. Sac'ing the Queen is the way out for white though.
Actually very good, I'm a 1400ish player and got pretty close to the 1800 answer. However, my take was to open up the king by taking the pawn in order to avoid g3, and if king takes then rook and queen could bomb it, and if he ignored I could trade it for a rook, leading to loss of rook and bishop vs winning rook and pawn while opening the king. However that line fails since the queen can't contribute to the attack because in order for it to work Rg4 is required and it wouldn't work. So yeah, I got up to 1600 just fine, but failed in the follow up.
I found the level of 1600 elo pretty quickly, and I found he didn't have to take but I couldn't look further. Yet I'm 450 elo, and pretty stuck there. :/
I calculated and found the best line pretty easily but I definitely should’ve considered more of white’s strong moves
I started playing Chess this week and have a rating of 230 or something and got the 1600 solution. It’s so cool to see all the different ways to solve things.
4:20 I completely missed that the queen could take in my head! I was imagining that the bishop was still there in my calculations, so I just took the pawn with my queen. We'll get 'em next time!
I think something went wrong in my calculations with Qxb4, because in my mind that was an optional move because it didn't adress the attack at all(I was wrong), so because I didn't think it would affect the game, I completely ignored it, when I shouldn't've. I was completly bind to this move for a while until 7:20!
Conclusion: Spend more time considering intercepting pieces, and when a piece moves/is revealed to get more squares, i.e. a reveal attack, to make sure I know where all the peices are moving.
What are your takeaways? Feel free to review with me!
I got the 1600 one and calculated the refutation a bit but gave up while being 900 rated
I’m over the moon I’m 1400 and I sometimes get the 1600 move in these puzzles but this time I found Rg4, maybe a little lucky as I know it’s a puzzle I don’t think I’d find that in a game to be fair and I wasted time thinking about Qxh4 stuff and deduced it lost a rook bc of the forcing checks, didn’t notice the queen would’ve been hanging anyway 😂😂
I love these videos I’ve only recently discovered them, the puzzles you choose are great in forcing me to think both tactically and strategically and I love how you explain at every level how to think in order to improve to the next level
Im 1700 fide and I solved it. It took me like 10 minutes because there are many options, but after Bxf3 I think the line is very forced and it is not really difficult to calculate it, you just have to keep calculating deeper and deeper until checkmate
My self steem has been greatly improved, thank you sir !
Well according to this I got somewhere between about 1800 and 2000, but my actual rating is closer to 1000.
The puzzle ranking comes from people playing the puzzle, and the puzzle rank is traded off the player rank depending on if you or the puzzle wins, much like the ELO of two players.
Got the 2700 variation complete quite quickly but with Qb7 instead of Qc5 which is probably a bit stronger
I’m 1100 and say the 2700 variation and was shocked when you didn’t say Queen takes right away, I did spend like 4minutes calculating it though as I really wanted to find the answer, my first instinct told me to take the knight with the bishop and saw the 1600 variation right away. I feel like it’s a lot easier to solve these when you know it’s a puzzle, lots of my chess positions are losing and I don’t think to solve it like a puzzle lol
