Great video! For the first puzzle, you forgot to show the incredible line after Nf5. You go Qf6!! Threatening both Qxa6# and Ng3# if the night moves, uncovering the defence of the bishop by the queen 🤯
Thank you I was thinking the same thing
ah yep 1...Nf5 2.Qxh5? would allow Nxe3 controlling d1. I missed that as well when watching the vid. 2.Qf6 is beautiful :).
@@Mylittlebaby10 no, g1 is controlled by the white bishop on f2.
Beautiful puzzles. I love all the different knight moves in the second one.
Nice and simple little puzzle to start the day off with. Lots of possibilities here to be found.
One thing to note with puzzle 2... for the ones where White plays Qa1, Black can play Rf5 to prevent Nf6#, but now you can play Qd4# instead, since the Knight is guarding that square and the Rook is no longer present to capture the Queen.
yeah i also thought of that, but later in the video he says that the rook has to stay there to guard the pawn
I’ve tried composing some puzzles and it’s so difficult. Not that I thought it would be easy. But I have to keep screen shotting where I’m at to try and progress it later. All it takes is for one little escape route or unprotect-able square and the whole thing collapses. Quite fun though!
When you finish one send it my way!
@@ChessVibesOfficial Nice reach-out. I agree.
@@ChessVibesOfficial I could send you a study or two of mine (prized) but no idea where to send them to?
@@emphyriohazzl1510 If there's no e-mail address or other social media contact to be found, you could always comment them underneath a video.
Wow you upload really frequently and I like it. Awesome video as always.
Everytime I found the right move, I always doubted it, lol. Great video as always!
Amazing composition around 100 years ago. And the possible pawn promotion, with or w/o capture, is insignificant.
Pawn at E7 takes Bishop, then as a Queen, back to C5 and then to C4
-Checkmate in 3
You could also go with Queen to H7 as the first move and it'll also lead to a mate in 3 no matter what black does
I thought the same move
Yeah you’d win in two moves, not three.
@@BattleshipAgincourt if they block the with the knight then its three
Enlighten me...after Qh7 white plays Nf5. How to win in the next 2 moves?
Can’t do it because Qh7 F5 Qxf5 Nxf5
I thought the same though, tricky pawn move to spot
For the first position, I believe e8(Q) or exf8(Q) work too. Without moving the bishop, the new queen can maneuver to the needed diagonal. (Or black's knight captures and allows the old queen to do the same.)
On move e8 black now can play bishop takes b4 with idea to check white king on d2. If you are playing exf8, then black have move Nf5
@@user-zz9xb5ee6z How can Nf5 prevent mate in 2? Either queens can just move to C3 or C5...then go to white square...mate.
@@darzgwapo Ng3 -> Ne2 blocking white diagonal
@@user-zz9xb5ee6z
After Nf5 the knight allows the queen to access the diagonal. If either queen moves to c3 or c5, Ng3 indeed stops it.
I then found Qa1, threatening mate with Kb2 or c2 (or Kc2 threatening Qa1)... but just saw black then has Nxe3! So either check and/or a block on d1.
Qh7, Nf5, Qd3#
I actually found the idea in the second puzzle, but I wondered why it wasn't mate in 2
I love how from the given pieces in the thumbnail it looks like black only has a king and pawn and you’re supposed to push the white pawns for a stalemate in 3
For puzzle 1, couldn't you just play queen h7 and mate on d3?
Oh wow. I would have never guessed it. Brilliant
To do mate in two just move g3 knight it can still be mate in 3 because you can move a random pawn and then get the king
Nice one. I thought of promoting to a Queen and then check mate the king with a queen on d3, but than the knight is just in in time for blocking on e2 and it would become a mate in 3. Also with the bisschop black could go for a check by taking on d2, and again a mate in 4 is the minimum.
Awesome again! Question: is there any puzzle that Stockfish can't solve???
simple answer: no
long answer: no
For puzzle 1, the real conundrum is, how did the black king get there in the first place?!
First puzzle: I first thought there a mate in 3 without the initial bishop move: 1. QxB means that Q reaches C4 by third move, either via QxP on F7, or via C8. However N can reach E2 in 3 moves to extend the game to mate in 4.
For #1, another move is possible, it's Qh6, threatens Qa6 mate.check it out
Qxf8 then Qxf7 and Qc4# also works
i was thinking Qh6 to Qf6(if they use pawn to defend, which is the only slightly good defense) then to Qa6 checkmate, if they dont move pawn its 2 move checkmate
At 10:45, I noticed that if Black played Rook to f5 to stop the Knight, White can okay Queen to d5 checkmate
The first puzzle can actually be easily solved. You can do pawn takes f8 and promote the queen. Then you put the just promoted queen on c5. If black tries to defend that with knight to e6, you counter with queen to c3. No move from black can then stop queen to c4 checkmate.
In the 1st problem, one variant is missing: After 1... ♞f5 there is 2.♕f6! threatening ♕xa6#, 2... ♞d4/♞xe3/♞g3/♞d6 3.♘g3#
The first has two lines of particular interest to problemists. One you identified: after 1 … f6/f5, we have 2 Qg8 Ne6 shutting off g8-c4, but opening g8-g2 allowing 3 Bxa6# The other much neater variation is 1 … Nf5! As you said, after random N-moves, 2 Qxh5 and 3 Qd1 is mate. BUT after1 …Nf5 ; 2 Qxh5, black has 2 … Nxe3 stopping all mates. Instead 1… Nf5; 2 Qf6! threatens 3 Qxa6# and now 2 … Nd6 closes the line f6-a6, but opens f6-f2, allowing 3 Ng3# These variations show the ‘Valve’ mechanism.
can you tell me how Qh7 on the first move is not winning a mate in 3 as well ?
nvm, i figured it out, he just moves the pawn 2 squares
@@gildeddrake1479 Yes. If 1 Qh7? f5! holds everything. (2 Qg6 Ne6 and mates galore, but in four not three).
Thanks I couldn't find the continuation after Nf5 myself
My idea which is m4 I think was pain takes bishop promote to q then if black plays with the k any move u take the h pawn if he doesnt u take the k with ur promoted Queen and then take the h pawn and the threat is white square bishop to e2
You have great content, thank you for the inspiration to create my videos)
In the first one what if we play Bb7 Black move the knight to f5 we take the pawn on h5 and black takes on e3, do we have mate in one?
Holy shit, amazing
I have a solution to #1: Qf8, Qf7, Qc4. This is mate in 4 if black plays nf6, but this is still an easy-to-see solution unlike the original one.
I thought I had solved the puzzle with Kc2, combining backrank mate, zugzwang and similar ideas from the solution. It almost worked but unfortunately, f5 (or f6) Qg8 Ne6 stops the mate for one more move. Still, I find my move even more pleasing than the solution.
In the 2nd puzzle, when the queen moves at a1, what do you mean black can't stop Nf6? What about Rf5?
10:59 u forgot one line to mention if Rf5, now Nf6 is no longer mate because black just takes the knight so u have to play Qd4#
I'm not even lying, Bb7 was the first move I saw and im just a 1900. wow. I can't believe this
Puzzle 2: you forget about black rook to f5.
I’m pretty sure the 1st puzzle can also be mate in 2 if the opponent doesn’t notice, if you play queen h2 and they don’t play knight f5 you play queen d3 checkmate. If they do move knight to f5 you take and then finish with queen d3 checkmate again! If anyone finds This to not be accurate please could u tell me?
You mean H7? They can move the pawn to block the line, which is then defended with the knight. Took me a bit to see why it didn't work.
Hello, I am a beginner to the Sicilian Defence. I decided to start with the Dragon Variation as it is apparently good to start with. I have memorised it and the Hyperaccelerated version. Any tips? 🤔
Immediate edit: I do understand the basic meaning behind every move just to clarify
Rating?
@@jaideepshekhar4621 749
U need to train tactic, calculus, and strategy
1st puzzle mate in 3, black King to E2 is mate in 2 - so it is 3 or less or typically all puzzles assume loser will not make a move for a quicker mate or draw ?
In the first puzzle after Bb7, there is another reply of black, that is Nf5: white has to reply with Qf6 threatening Qxa6#. So Bb7, Nf5, Qf6, if Nd6, Ng3#.
In fact, after Bb7 by white and after Nf5 by black, white cannot play Qxh5 as per variation with black's move Ne6: Bb7, Nf5, if Qxh5, black can play Nxe3 and white queen has no more the check neither on c4 neither on d1 square.
Also in the first puzzle, Bc6 does not work because you don't have Bb5# due to black pawn on a6.
you forgot Nf5! the only move there was Qf3, threatening Qxa6# and if the knight blocks, Ng3#
the option is queen to h7 knight to f5 queen to f5 takes the night bishop to e7 final move for white now is queen to d3 and its a mate
Great video..
As for him liking checkmates in three maybe he was a religious man in that 3 represents the holy trinity or simply because 3 is a number with religious connotations. Just a pondering thought.
Hey just an idea - maybe a series on the how & why of why masters resign. At times a lot of us patzers have trouble seeing how & why masters resign and thought you showing us solutions would be highly instructive
Can't the Queen > a1 version be stopped by black playing Rook > f5, which prevents Knight > f6 as the rook can take it?
Never mind the video portion the picture portion of your video just kicked in after several minutes! That was weird But it’s OK now I can see it
My engine didn't see bishop b7 running for a while until I played it lol
I'm bit confused for the second puzzle, I'm thinking about a mat in 2 : Qe5+ black takes with rook or pawn and then Nf6# I can't see if I miss something
Nevermind, if you take with pawn, then the knight is pinned. Would have been a cool mat tho
What happens in the first puzzle if knight to f5?
If is white turn, for first puzzle, knight to G3 is not checkmate in 1?
Why not just Qh7? Getting redy to checkmate Qd3？What am i missing.
For the first puzzle, if you take the bishop and make a queen, this is mate in 3 i think. If black move the knight, you Can put your Queen h8 to a1and then mate with move from thé king in b2, if black don't move the knight, Queen f8 to C8 and then c4. I don't find a way for black to cancel mate in 3 in this way
Isn't there a solution to the 1st puzzle by just pushing the pawn, promote to the queen and then either Qa4 - Qd1 or Qc3 - Qd3 depending on whether knight captures new queen or not?
I'm just reiterating previous comments.
After e8Q black plays Nf5!, and after Qa4 Nxe3 delays the mate in d1 for one move (becomes Mate in 4). After Qc3 Ng3, Qd3+ Ne2! also delays one move
Puzzle 2: you said black pawn to b3 twice
first puzzle: h6(Q) then a6(Q) = mate, black can´t stop it. What i miss?
you may the wrong move, there mates-in-1 move after bishop to B7
First position wouldnt Qh7 then Qd7 work too?
Puzzle 1 - Pe8, if he captures with the knight Qd4, Qd3#, if he doesn't capture Qc6, Qc4#, simple as that, because king can't move nor capture any pieces your queen just needs to not be in danger and to attack the king and its checkmate. No bishop shanenagans needed.
Black plays Bxb4 and will delay mate by giving check.
@@ericlindholm9482 hbt taking bishop at F8 then if black moves pawn
Queen to C8 and to C4
If knight moves Queen to A1 and move the king away after that
On the first puzzle you missed black promoting the pawn
on puzzle 1 i thought of Qh7 then black blocks with Kf5 then Qxf5 then black cant do anything to block Qd3
Is 1. Qh7 blockable for M#3?
Not watched to the end yet, but for the first puzzle what’s wrong with e8? According to me if you promote to a queen black can either capture with the knight or not. If they don’t then Qa4, and Qd1# looks like it can’t be defended. If they do take, then Qa1, followed by moving the king off the back rank for mate. What am I missing?
The move Nf5 fails the mate in 3 by 1 move
1. e8Q Nf5
Now both 2. Qa1 and 2. Qa4 will be followed by 2... Nxe3! and d1 square is now controlled, delaying the mate by 1 move, making it Mate in 4 instead of 3
I found a slightly different and (I think) workable line for puzzle 1. It starts with a promotion of the pawn to a queen, which the knight would have to take before the promoted queen becomes a nuisance. This both gets that defender off the pawn on h5 but also opens the diagonal for the queen on h8 to come down and deliver mate with two other moves. Honestly not sure why Bb5 was the only first move to kick off that puzzle, it seems like there are more solutions here. Can someone explain why I'm wrong?
The knight wouldn’t have to take the Queen. You only have 3 moves to checkmate so from what I can see it could go to E6 then D4 and then F2 preventing the 3 move checkmate. It looks like you have checkmate in 4 but not 3.
I meant E2 on the final knight move
Advance pawn and promote to queen. If knight takes, move queen (only one now) to either D4 or E3, 3rd move (regardless of what black does) D3 mate. If knight does not take queen, move E8 to A4 (regardless of blacks move), then on 3rd move, A4 to D1 mate. Have I made an error?
@@ericsnyder3543 Black responds with Bb4 and Bd2+
Very nice puzzles.
But I can't believe that you say "Zugzwang". 😀I love the way you say it.
I'm from Austria and of course I know this word, but is there no word for it in English? 🙂
Am i stupid? First riddle, cant you just go Qh7 and no matter what black does, white either mates in 2 with Qd3 or, if black blocks with Nf5, its mate in 3. What am i missing? Im still new and learning, be kind :3
Ke2 is Mate in 1 for white right?
Why doesn’t knight g3 work on the first puzzle?
First puzzle. Isnt it possible to move the pawn and get a queen. If knight takes then queen moves to a1 and king moves to c2? If knight doesnt take then new queen moves to a4 and later to d1? Is that a solution or am i missing something?
Black responds with Bb4 and Bd2+
In 1st position, E7 takes bishop. Either new queen or old queen can checkmate in 2 moves depending on where black puts the knight. Please explain to me if I'm wrong.
@@wingit7335 Sorry, I was wrong. Knight can prevent mate in 3. Easiest way is Nf5 then Ng3. Then when white checks, Ne2 can still cover the king so not mate in 3.
@@wingit7335 Yeah but still knight prevents that by blocking the diagonal protecting the king after check.
I wish you'd share the png of these.
In 2nd situation I'd like to see what if after white knight f6 Black goes for rook f5
Chess Vibes in Puzzle 1 the pawn shown on G2 has black king at F1 in check throughout the puzzle. Black was already in checkmate unless there is a rule I don't know about. And the pawn could push forward and promote to queen and checkmate anyway as it is protected by the bishop.
I am so sorry. I just realized that the black king is on white's home row. As usual, early morning thinking is foggy.
That’s why Nelson always says, during the intro, while drawing arrows, in what directions the pieces go. As a general rule, ‘white to move’ puzzles have white on your side. Also, bottom left is A1.
Why not Qh7 and after e5, QG8 and QC4 after a random black move? (Puzzle 1)
It was first intuition as well, but there is the absurd Ne6, and we are left with a #4. Good enough for sure. I don't like this puzzle for that reason.
@@j.thomas1420 yeah I see... But in real game it's the move... Well, in real game black king doesn't go here lol
@@bjornlerouge couldn't agree more...!
I'm a beginner so have probably missed something on the first puzzle but how about Queen to H7 and then Queen to D3. That's mate in 2
unless black plays Knight to F5 in which case white Queen has to take it first, so mate in 3?
Just got my mistake. Black pawn to F5.
Check or checkmate? I was taught you are allowed 1 square between kings so E1 (never really mentioned) would avoid many cited examples of checkmate. Not saying it's a good move just confused why it was never once mentioned. Have the rules changed?
e1 is guarded by the white bishop on f2 so the black king can't move there
Rook captures Nb5 is not checkmate because after Qe5 instead of using the pawn to capture u can use the Rook which the forces the knight to recapture it and checkmate avoided
for the first puzzle i thought it was e8=Q but apparently knight can be annoying making it M4. oh well
In the first puzzle pawn in F8 it's also mate in three if I'm not mistaken, being either D6, A6 or C3, C4/D3.
thought so too. but knight E6 can prevent every mate in two

After 3 minutes looking at it Q-H7. Knight blocks. take knight. doesn't matter what black does after that next move is checkmate with Q-D3
Now i will watch the rest of the video to see if I missed something.
Won't get there in 3 if he pushes that pawn up two. I would take 4 moves. I was WRONG! LOL
For the first puzzle, does Kd1 not work somehow? I would think that it puts black into a similar position of zugzwang, and the light square bishop won't be in the way of any of the follow-up queen moves.
EDIT: Actually, it doesn't work for a surprising reason - black can suicide the knight to deliver check on the white king, winning a tempo and forcing the mate to take an extra move! xD
or abt knight g3 on puzzle 1
if we scarifice a night for 1 move before mate it is mate in 3
I think promoting the pawn to Queen in e8 works to because if the Knight takes it then the queen in h8 can go to a1 and there is no way black is going to stop the checkmate. Black bishop can go to g7 but the queen can just go to b1 and black can't do anything to stop the checkmate. If the Knight doesn't take the queen in e8, the queen can go to a4 and checkmate by going to d1.
Oh, I just saw that was mate in 4.
Puzzle 1
at first look i figured out first bishop move but didn't got queen move
Anyone like me who found the two move almost mate for the second one but didn’t notice the pin? 😭😭
Hi, if I'm not mistaken, there seems to be mate in 2. Queen to h6 followed by Queen to a6
Then knight to e6 will block that path, right? I think Queen to h7 might be great with following step to d3.
@@soksovanratha5958wouldn’t that make it a mate in three?
Are there three puzzles, was there a typo, or am I losing my mind?
I think there might be a possible miss on a different checkmate that is easier to spot. White E pawn moves forward 1 square and upgrades to a queen. If the black knight takes, the white queen moves down the diagonal to A1 then next move Whites king moves out of the way. If black does not take the queen on E8 then that queen moves along the white diagonal to A4 I believe then next to D1 for the mate. Did I miss something?
Nf5
If the pawn move forward it allows the black bishop to capture on B4 then D2 sacrifice orA3 giving white king a check which will delay the checkmate by 1 move
But what to do in puzzle 1, if black will go nf5? I i didn't find the solution for this one becasue for each other white move black can sacrifice thier knight with moves ng3 or ne3 depends on white move.
I found the answer - qf6, then based on black move qa6 or ng3
The king is on f1. Or did u mean Nf5?
@@Adventurer-te8fl yes, you are right, I mean knight, but forgot that in English knight move i should write with n, not k

What is stopping white from going Qh7 and Qd3 after? You have mate in 2, king is Trapped and there isn't anything that can take queen? Or am I missing something? Just started with chess and it's really interesting

Yes f5 is ok

Waaaaait Oldřich Duras is from czech republic???? Omg i didn't notice😂
the puzzle is okay but if we just simply plat queen h7 after that queen to d3 its mate . black can delay mate by placing his knight on f5 but it still is a 3 move mate (That's Easy) :)
Am I missing something? King to D1 followed by bishop to E2 is a mate in 2
Then black king will escape at G2
It's a scientific way of thinkin
IN THE FIRST PUZZLE IS KNIGHT TO G3 NOT MATE?
Dang I thought QH7 threatening QD3 I saw the knight delay on F5 but somehow I forgot the pawn could go to F5 obviously instead. And then protected by the knight. I didn’t see it until i continued the video and said first move was bishop and I was like what? Then I saw it….damn….
