So Stockfish was like: "Actually that doesn't work because of this. However, if you do this instead, it does work, so nice puzzle anyway, you just got the wrong solution."

Refutations of old puzzles are the best chess videos. Thanks for posting and please make more

Stockfish out here delivering patch notes to old chess puzzles

[Mintbun]

Imagine if someone refuted these puzzles before stockfish was invented

I found Nd7 because you said the move was crazy, I didn't know why Nd7 was good I just knew it was indeed crazy

[KolejowySzynszyl]

Stockfish doesn't ruin chess, it finds moves and lines that weren't expected.

[matthewviramontes]

You don't even need Stockfish for this one. There's only 7 pieces on the board, so it's a tablebase position, and the tablebase will tell you right away it's a win for White and tell you every winning move too.

[skyblue-phgq]

Actually, there are exactly 7 pieces in the board and we can use a tablebase. After Rg7+ Kh8, white has 3 winning moves: Ke7, Rg6, and Ke6.
(+ Rg6 repeats the previous position, so white has to move the king)

Not only Stockfish could find these other solutions. Looking at the 7 pieces Tablebase would have told us the same…….

[Joseferberger]

Nd7 was actually quite intuitive once you mentioned the stalemating idea.

[Caladian]

I did intuitively guess the knight to D7, based on what you said previously about taking away the pieces of black would lead to a draw. I didn't see it though of course, just since you asked that was the only move I could think would create a situation based on what you said previously

[vivaankohli]

Thank you so much for the video. That was a really nice solution. I like how Stockfish finds these lines and moves that we didn't notice when originally looking at the puzzle.

[justfrankjustdank]

i found the move cause i though "ok getting to that squares important, how can we block it" and the knight is what i saw first lol

[TheChamp]

At 5:06 I figured Black would play Nd7 ONLY because you said they could draw the game with a crazy move.

[tsa_gamer]

In the stockfish variation, Ke7 doesnt win as after Re1+ anywhere king moves, black will play Rxe8, and now you will notice that black has removed the defender of the white rook so if white king takes blacks rook then black king takes white rook and then eventually black king will take the pawn as well and its a draw. Otherwise after black rook takes white knight, if white king doesnt take the black rook and defends white rook, now you are just a piece down, though a pawn up but you cant just pull up a win from this, eventually rook trade will happen or you will lose your pawn and white if plays accurately then will draw the game.
Ironic how white had to win but after stockfish recommendation, white had to push for a draw

[David_Crayford]

Beginning to feel sorry for the old masters. Computationally they didn't have the bandwidth to go through all permutations in one lifetime!

[spartanspeedruns]

Really happy that I found Ke7 at the beginning of the video lol. The whole video I was like "but what if you do Ke7 instead?? Pushing the pawn didn't seem best there..." and then you finally went back to that and I was like "yes!!!" haha

Composer🕵️: Hey everyone! Look at this chess puzzle I made! It is white to play and win and ends up having a "smothered mate" using a pawn♟️

**Stockfish joined the game*
Stockfish🐟: You sure about that? Checkout this knight🐎 sacrifice to draw the game.

Composer🕵️: Oh-- **sad noises*

Stockfish🐟: Don't worry, there is another move for white to win the game, just use and move the king🤴 already closer to the black's.

Composer🕵️: --oh ok

[alex_zetsu]

Normally I'd say "it's a win for the intended side, just not the intended way" is not really ruining a puzzle, but a pawn checkmate is pretty cool...

[gresach]

Thanks for this study by Gorgiev. It’s not just 2.Ke7 that wins but also 2.Ke6 or even 2.Rg6. So the problem is actually savagely dualised. If one uses Stockfish with 5 parallel searches, I suppose it will pick these up, but easier is to use a tablebase like Syzygy. Question really is how to fix it, if possible.
