That's easy. You play 0-0-0-0(long vertical castling) by playing Kg4 and move the rook to G3 check and ladder mate.
Queen attacking g2 square so it not possible😅
@@3loyhusky but my king and rook will be safe from any attack. Just g4 and g3 are safe.
You... can't castle through check...
And, by the way casting works, the rook would be moved to g2, therefore being endangered by the queen...
And the king has already moved... "unless it's 960"
there is a rule against this just because someone tried it in an actual game
I love how you all are focusing on the fact that the king will pass through an attacked square, when none of you consider the obvious. That the king will end up on g3 instead of g4.
Very nice puzzle. These kind of end game positions where there is only one route through are so difficult under time pressure and its useful to see them played out like this to develop an intuition for the right kind of solution, even if there is of course no substitute for calculating them out on the board.
This is why I tell people to play 15 or 30min games instead of blitz right away. I would say you shouldn’t play blitz until you are about 1600 player
I was thinking of trying to find a mate after putting the rook on g5 to g4, but then realized it would just end up as a draw
Great lesson, Coach! Thank you.
Im really liking these interesting little 10 min puzzles
For a puzzle that was literally composed during Paul Morphy's time I gotta say this is pretty complex.
Why isnt rock to f2 the play instead of king to f2? Any follow up from the queen and the king can slide put
That was my first thought too but after Qb8, Rf2, Qg3+ prevents the king from going to G2 or H2. Either you end up blocking with the rook and the position will repeat or sliding your king to f1 basically recreating the position shifted to the left
Hi Nelson great videos but one sincere request, can u please bring back the extro song at the end of the video? It just feels incomplete without it!
Interesting version that was omitted: 1.Th3+ Kb2 2.Tg2+ Kc1 (or Ka1) 3.Th1 Qb8 4.a4! (4.Kf2+? Kd2 Kf3+ Kc3 X)
i found a few of those. the ladder up aswell as the switch and the move king to checkmate. but thats about all
Luigi Centurini 🇮🇹, a very important theorist for Italian and world chess!
Thanks, giogio
What about Mario Centurini? ;)
@@Trias805 ?!
Hold on.
After Rh3+, what if black responds with Kb2 instead of Kxa1?
Then after Ke3+, black would be able to play Ka3, and you can't play Ra1+ because the pawn on a2 would be in the way.
I have an interesting idea to win: after black played Qb8 (to avoid Kh2+), white just can push the pawn, a4-a5-a6, etc, finally black has to take it with the queen, and then Kh2+ wins.
@invenblocker
Yeah, important variant. In that case, white does not play 4.Kf2, instead going for 4.a4. Abusing the fact the back queen cannot stop the pawn without losing sight of h2.
@@ariadeninstead of King the F2 what about rook to F2 no way to stop mate or losing queen
@@joerichardson6107 That was my thought, too. Evidently Black can draw the game, starting with ... Qg6+. If White interposes the rook, Black returns the queen to b8. If White plays Kf1, then Black plays ... Qg4, covering both squares that would result in a mate the next move.
1. Rh3+ Kb2
2. Rg2+ Ka1
3. Rh1+ Qb8
4. Computer says to play pawn to a4 and the black king is trapped
(I used an engine)
Hi! Have you covered the impossible Tim Krabbe 1972 position, after which they’ve changed the chess rules?
I see nobody on TH-cam have yet. Go ahead!) hi from saint-petersburg 👋
Is this the one where you promote to rook and then castle lmao, I don't remember all the different "impossible" positions 😂
Remote chess academy did this
@@justarandomdoodthat's the one 😊
nice, i dont ever think of these positions and end up stalemate or losing stupidly
what about rf2 when you have the rooks in h8 and g7 and after that go king g2 or h2
The rooks who mated the queen then the king at the end of the puzzle 😳
The analysis misses Kb2, in that case after Rh1 the Queen is stuck guarding the h2 square and you advance the pawn!
it's a me mario
Ladder check mate, I remember that when I was a beginner, it was my favorite cuz it was the only I could do hehe
After Queen b8, move the rook f2 and mate
Protect the pawn, force queen.
When position was Rg2 Kg1 Rh1, just move play Rf2, its mate in 1
Even if you check with the G rook it still works, when you get to the point where yhe rook is on g3 you move it to e3, at which point it is clear of the king, the only move black can make that isn't an immediate loss is queen to g8+, at which point ypu block with your h column rook. She can't pin the e column rook she can't take the g column rook, she can't fork anything. Her best nove at that point is to take the rook, lose via rook and king checkmate.
I've always wanted to know why your arrows are red instead of orange-- are you always holding CTRL, or maybe a mouse with extra buttons? With chess TH-cam content being so similar, I think it's one of the things that makes your videos stand out. I don't think I necessarily click on your videos because you're "the red arrow guy", but honestly.... maybe I do!
Thank You!
I played it with the computer. What if black doesn’t take the pawn? Isn’t that a whole line that needs to be analyzed?
there is a flaw. instead of taking the pawn the king can go to b2 and as you said except at the end black can play Ka3
It doesn't work. Once the queen is stuck guarding the h2 square she MUST stay on that diagonal. That means white simply walks their pawn up the a file with the queen unable to stop it. If the queen captures or blocks the pawn, white gets an immediate checkmate at Kh2.
Not really insane, but it is elegant. Thanks for sharing!
WRook h3, Bk B4, Wp a3 checkmate. If Bk takes pone over retreat ladder from there
Finally a chess problem thats older than meee
@ 5.22 what if rook plays f2.. Next whatever white plays... Move king in any one of g2 or h2... It's checkmate or queen gone
Wouldn't Rf2 instead of Kf2 force a checkmate or queen sacrifice though?
Qg3+ looks a little scary in that position, I don't see how white makes progress in that line
Would end in a draw because of queen g3
@@isaacchen3857 you can't win the game if they'd do qg3, and if both sides continue with perfect play
_Rf2 instead of Kf2_
That was my try too, but I don't think it quite works.
@@rogerkearns8094 It doesn't, ends in a draw
Actually, it's not exceptionally difficult. Ra4+ forces the Q to capture. If the K captures, or moves off the file Black drops his Q and 2 Rs against a bare K is an easy win.
After the Q captures, you partially pin the Q by putting the R in front. If QxR, the pawn promotes with check winning the Q. If KxP, QxR winning.
Just ladder and you'll eventually win the queen then u can promote the pawn
Why not Rf2 as an answer to Qb8? Now White King has more opportunities to step aside letting Rooks to mate the black king. It seems simpler to me than letting king take a walk.
Exactly, i cant find any way to not win at the next move. The queen cant block both g2 and h2 for the king to escape.
I was thinking this myself. Qg3 ruins the plan though.
Nice one!
at5:50cant we also do Rf2because it wins if the queen goes to the g file to check you well you go Kh2 ggs
What role does the pawn on a2 play ?
If there was no pawn, Black could get his king to the c file before white goes to Kf2. That allows black to get their king to escape to the d file so no skewer is possible. Black MUST capture the pawn with their first move or else the pawn will advance and promote. Yet to capture the pawn means that black's king can't avoid the skewer trap by reaching the d file to escape.
At 4:28 what happens if black sacrifices their queen and takes the rook?
Hopeless endgame for black, easy win for white...
A main variation wasn't covered. After 1.Rh3+ Kb2 2 Rg2+, Black can decline to capture the pawn and play Ka1. White still plays 3.Rh1 Qb8. Now 4.Kc2? is a blunder. Black again declines the pawn and plays Kb2, and after 5.Ke3+ Ka3, White no longer has the skewer, because the pawn is in the way.
White can counter that by getting the pawn out of the way with 4. a4, and now Black can shut off both of the White King discovery checks with Qf4. White continues with 5.a5. Since Black can't move the Queen without letting White's King out, Kb1 is forced. White continues to advance the pawn, and Black has too many threats to counter.
5:47 Rf2 is just mate in 2 and you just need to remove his check
No because Qb6+ and when king moves to h1, Qc6 pinning the Rook to the king.
Its sooper easy bro. Rook to a5, queen takes rook, pawn promotes to queen with check .. king moves and queen takes queen :)
Can't black head off Ke3? If he always approaches instead of takes on a2, he can be on d2 at the key moment
I’d say G5 to G2 the first move
Does it make a differens, if black doenst take the pawn?
Yes, then the pawn advances up the board and promotes. The queen has to protect the h2 square once white is threatening checkmate so she cannot capture or block the pawn.
5:25 what happen if i put rook to F2?
The queen gets a series of checks and eventually captures a rook.
This video gives only half of the solution to the puzzle. What if black king doesn't take a2 pawn?? The black king can hide on a3 and white rook cannot check from a1 to force the white king on b3 to create a screwer to take the black queen on b8.
Doesn't work but I'm glad you thought of this option. Once white threatens checkmate at Rh1, the queen MUST protect the h2 square. That means once she is tied to staying on that diagonal, white can simply saunter his pawn up the a file. The queen can NOT capture the pawn without an immediate checkmate and the king wasted his chance to capture.
@@tykemorris Exactly! This is how white actually wins. But this main idea is not shown in the video. White wins because black goes into zugzwan.
Here’s what I did:
1. ... Kb4 2. Rg4+ Ka5 3. Ra3+ Kb6 4. Rxa8 Kb7 5. Ra5 Kc7
6. Rg6 Kb7 7. Rh5 Kc8 8. Rg7 Kd8 9. Rh8#
I spent 30 minutes looking for the single move checkmate, lol. I didn’t know it was white to play and EVENTUALLY win
Why cant queen sacrifice and take rook at g2 instead of king going down to a1 ? Qg2 instead of Ka1 ? that way we can eliminate 1 rook right ?
Yes, but you can checkmate the opponent with just a rook and your king. So its a 100% losing Position if you trade the Queen for one of the rooks. You just have to know the pattern how to checkmate, but its pretty easy. The Queen sacrifice only works if the enemy has not enough Material left to checkmate you, like just a Knight or bishop
The pawn can promote as well
good one
At 6:03, what would happen if queen checks instead of moving the king?
Rook takes Queen, King takes Rook, and standard single Rook+King checkmate procedures will eventually win.
This puzzle is just so easy LOL
I had it solved until you talked me out of Kf2. Lol.
Okay once you go down to the white square in front of the white quick King why not just take that Rook with the queen because it'll be nearly impossible with that much space between
Because then the king takes the Queen, and single Rook+King against nothing is enough to force checkmate.
Why are you suggesting moving the king to e 3 not rook to H 3
Impressive.
5:07 why not rook f2 and next move is mate?
it not work when the king go b2 instead k:a just leave the pawn
5:25 rook from g2 to f2 also work I guess
@@keremaydogan9323yeah you are right
1Rh3. Kx a2
2Rg2. Ka1
3Rh1. Qb8
4Rf2 now black has to plan for queen sacrifice for a rook to avoid quick mate
Now try to save pawn 😂
Mate in 18 [Stockfish says]
Queen can take a rook at almost every step of the plan, sacrificing it and making a draw. Not a win(actually that's even worse than just a draw, because white had more material (11 vs 8).)
She can take one rook and then black loses the queen. That leaves a rook and a king against a lone king, a certain win for white, not a draw.
At 5:26, why not just play Rf2 - now the king has 2 squares it can move to in order to uncover the bottom rook and deliver the checkmate; and Black can't control both of them from any square it can reach.
Rf3 is better I believe. They’ll just check your king and make the game a draw
@@mrwolf9095 How is it a draw? As soon as the king dodges the check, either to g2 or h2, the queen will have to block the check and then it's checkmate.
What am I missing?
@@Polymeron "why not just play Rf2"--
Black then plays Qg3+, which covers BOTH the g2 and h2 squares. If white then plays Rg2, then black plays Qb8 repeating the position. Do that 2 more times and its a draw by three fold repetition. If white instead plays Kf1, then black plays Kb1. White can make some rank 1 rook moves but black can always stop the king from getting behind the rook on rank 2, so he will have to go in front of it. Then the king can escape but the queen wont be skewered and will still be active.
@@fomori2 Ah, thank you! I'm not sure how I missed that, you are right of course 😊
@@fomori2queen g3 is an eligal move
I found a bit odd that u didnt go into the g4 or h5 idea too much if u immediately block the checks with the rooks both diagonally and horizontally
Once the queen is free, black can force a draw
@@Fenrir7 it wouldnt be exactly free tho cuz it would be in the corner w the rooks protecting both angles where the queen can check. Said this because he does mention putting the rooks next to eachother but then doesnt mention the most logical moves after doing that
@@rolef6084 After Rg4 or Rh5, the queen will go a7, b7, b6, c6, then will just travel up and down the c file checking the king every move, and there's nothing white can do. If white trades a rook for the queen, then black captures the pawn and a rook+king vs king end game is a draw.
@@Fenrir7 yh i thought you didnt understand now i know for sure. thats the move he explained im talking about the one he didnt explain. rg4 a7 rd4 blocking the check qg7 h rook to g4. now no checks are available for the queen. lining up the rooks is stupid if u dont intend to use em to block the checks and just let them stand there lol
oh and rook + king vs king endgame is not a draw lad. by forcing into a corner w the king u can checkmate w the rook@@Fenrir7
Effectivement
I'm not good at chess, so could someone explain why moving the top rook to b3 isn't the right play? ts: 4:42
Because the king can just keep moving away from you forever so nobody would win (a draw). You need to some way to threaten checkmate or something to avoid a draw. If you go to Rb3+, Black would just Kc1. Then you go Rc3+ so black goes right back to b1. You never get anywhere so the game is a draw, not a win.
Yes. Not an easy one. But compared to your other puzzles it's super easy. 😂
1:52 just go E3 with rook lol
Qa5?
Two is better than one
What if the Black King goes B2 C1 D2 ?
Yes, THE PAWN goes for it
A 2.Pon ??
Solved
1:39 Rb3?
5:50 why bot Rf2?
Black goes Qg3+ and from there, the best white can get is a draw. The skewer trap is lost and black can easily prevent the king from ever getting out of the first rank as the black king slides over to help capture the rook. It gets messy.
Kb1 loses to Rb3, the real reason why this line fails is because of Ka1
Too complicated. What you do is get the king to move onto the a-file, then slide a rook over and fork the king and queen :)
Greats from Germany
Okay I didn't like the way you worded the puzzle when you say one move and when I think one move and mate I don't know why I thought that
4:40 5:12
How come black Queen can’t just take the rook???
Sure white king then takes the Queen, but now white only has one rook left.
One rook left is a certain win for white.
Rook to G5
RA5
5:00 but what about Queen takes g2? Wouldn't that result in a drawn endgame?
Me, waiting to say i can't do Rook,King, Cheakmate: 🤡
Just bear in mind 3 ideas:
1. The opposition King can't cross a file controlled by your Rook.
2. If your King is opposite theirs and you check from the side, their King must move backwards.
3. It often occurs that its better for you if it's their turn to move, so use tactical waiting moves.
Use those three things to force their King to the side or corner, then checkmate.

Nice
I was first but that ads cut me off!!
NO - I was first, but I felt sorry for others that wanted to be first - so I deleted my comment. But nice try!
That was the easiest puzzle ever existed in this chess universe.
Even if he forgot "What if the Black King goes B2 C1 D2"?
What if Queen takes g2 and force a draw
exactly what I was thinking, finally somebody found the obvious. only 170 years too late.
Rook+King VS King ≡ easy win...
@@KOPOJLb_King I searched Google and there's a 50 moves rule so if the black plays clever then black can draw right?
@TuanAnhLe-wn7gk , you can checkmate opponent in 16 moves or less in any start position...
Of course, if player with extra rook would play badly - game ends in a draw, but if not... then easy win 😀
Pawn A1
Cant black just sack the queen for a draw? Newer to chess. Can you checkmate with a king and rook only?
You can, although if you don't know what you're doing, you can run out the 50-turn draw clock if you're not prompt about it. Look up king and rook checkmate on Google, it should show some examples.
Hello
Hi
Why couldn't black just trade their queen for the rook when the rooks are in the corner and draw the game instead of losing?

Very bad analyzed. you just don’t consider black’s best moves 😂
