I've seen thousands of chess puzzles but this one may be the most amazing of all. Nelson's perfect commentary enhances the beauty of the composition.

In 1995, John Nunn shortened a study by Matous to produce this position, as an engine-stumper. It's interesting that it continues to stump engines today, almost 30 years later.

Really crazy how Stockfish does not focus on "wayward" moves (like the move that it does not detect) but rather "direct" moves that are straight to the point but creates a draw in this instance! This is for Stockfish to be resourceful on memory by eliminating "wayward" moves that have less chance to generate a win and giving more depth to the moves that seem more "winning". Good to see you back after disappearing from my recommendations for 3+ years! Time flies so fast!

@luckydust4375 3 ай бұрын

Yeah there is still some flaws with Stockfish there Maybe it would need to stop calculating drawing lines further and further when it's obviously a draw to focus on analysing previously discarded moves Like "ok this is a draw, now do I have a better option?" Especially when it have infinite time to think

Contrary to what the video claimed, Stockfish actually finds the long forced-mate instantly. Chess Vibes keeps using the bad default Chesscom setting that limits Stockfish's depth to 22 - an artificial handicap that weakens the engine considerably.

@tuxedobob2 3 ай бұрын

@@Rocky64 Does a depth of 22 count both white and black moves toward the depth? If that's the case, I feel like it shouldn't find forced mate in anything above M11, but it does, doesn't it? It's more likely that moving the bishop is a "weird" move that Stockfish discards early on.

@jameswang7362 3 ай бұрын

No, Stockfish (and Komodo) run alpha-beta searches, which evaluate the position for every possible (winning) move. It has nothing to do with intuition. If there is a mate in 12 and you let it search up to 24 ply Stockfish WILL find it - it's mathematically guaranteed. The depth was just artificially handicapped to 22 ply in this puzzle. You could say the same about a Stockfish limited to 1 ply and entirely relying on its NNUE heuristic.

Try analysing positions with Stockfish 16 instead of Stockfish 16 lite. The lite version is often a bit off. Stockfish 16 will find this mate before reaching depth 30. It's always frustrating to me to hear "Stockfish can't find it" and see "Stockfish 16 lite depth 22" in the corner. Amazing puzzle btw

There's another interesting line where white has to be very careful -- if, when the queen and knight are keeping the white king from moving black can play Nd5+, and if white moves anywhere except Ke6, Nc3 blocks the bishop *and* delivers a check on white's king. Black can then perpetually check until a 3-fold draw is reached.

Well, in the end, when white captures the pawn in a1, black still can avoid a humiliating checkmate by the white moving his king, by 1) sacrificing the queen in e5, bishop takes, Ne8 check, fxe8=Q checkmate 2) directly go with Ne8 check, fxe8=Q check, Qf8, Qxf8 checkmate. And the second case is also a nice trick for black, because if white doesn't capture the knight directly with the pawn, but still want to checkmate by moving the king to e6, then Ng7 with check, BxNg7, KxBg7 and black now has a winning position since white cannot promote to f8.

@kzkaa. 3 ай бұрын

This doesn't stop checkmate, but it does stop a humilating one.

@robheusd 20 күн бұрын

A queen move to a3 or g1 or a knight move to e8 can procrast the checkmate but not stop it. But knight to d5 with check will stop white from winning because after the white king moves with discovered check, knight to c3 blocks the bishop. Bishop can not take it because the queen defends it and the promotion square is also defended by the queen.

Nelson this one was amazing. Though the one where the oppenenets king was forced to move to one of 3 squares was my favorite and better than this one.

@terencemah8521 20 күн бұрын

I believe white Kg5+ is still winning, unless I'm missing something. After Black plays Qg7+, White plays Kf5 and Black can no longer stop f8=Q#, even if queen takes bishop, since the queen is pinned on the diagonal and can't deal with the pawn. If Black plays Ne6, covering the f8 square, then the king simply captures the knight.

I've played chess since 1966. It's common courtesy to refer to the composer of a study when you present it. You don't just write "local newspaper", " a bloke in the pub", "reddit" or something like that. This study was originally presented by Mário Matouš in Szachy 1975. You are showing a shortened version, where the first moves by white and black have already been played.

@simens8646 2 ай бұрын

At 10:00 you are going through many of black's variations, but there is one important variation that you don't show. Black could play Qf8 intending both to block promotion and also to block the white bishop with Qg7 if the king moves. This also loses, but in a slightly different way than other moves. White doesn't capture the pinned queen on g7, but simply delivers mates by promoting on f8.
