A nice game Caissa 1.18 - Stockfish 16.1 KNN vs kp

[chesskobra]

I had never witnessed a game like this. Caissa 1.18 won (in the end) an ending with king + 2 knights against a king + pawn without tablebases at 40 moves per minute. I am not sure if the ending is perfect according to tablebases, but still quite impressive at 40 moves per minute on an old laptop.

[/pgn]

I am surprised that Stockfish blundered by 50...Ka3 when Kc1 or Kb1 could be a draw.
my stockfish see the mate fast even without tablebases.

[chesskobra]

Until move 54, Stockfish has evaluation of 0 and Caissa's evaluation is positive but under 2. After Caissa's 55th move, all of a sudden SF sees mate in 30, and on the next move Caissa sees mate in 29. I am sure such things must be happening even at very long time controls on better hardware, and more so in earlier phases of the game. Incidentally, Caissa defended the original position with colours reversed.

The position is from a large collection of endgame positions (more than 157k positions, which I believe I got it from SF tests).

[Chessqueen]

I had never witnessed a game like this. Caissa 1.18 won (in the end) an ending with king + 2 knights against a king + pawn without tablebases at 40 moves per minute. I am not sure if the ending is perfect according to tablebases, but still quite impressive at 40 moves per minute on an old laptop.
NOTE; It is not just Caissa 1.18, Caissa 1.17 can do it as well

Until move 54, Stockfish has evaluation of 0 and Caissa's evaluation is positive but under 2. After Caissa's 55th move, all of a sudden SF sees mate in 30, and on the next move Caissa sees mate in 29. I am sure such things must be happening even at very long time controls on better hardware, and more so in earlier phases of the game. Incidentally, Caissa defended the original position with colours reversed.

The position is from a large collection of endgame positions (more than 157k positions, which I believe I got it from SF tests).

Something seems to be wrong in the game.
stockfish16.1 in console mode no tablebases and default small hash tables see mate score very fast in the position after 50...Ka3 at depth 23 after less than 300,000 nodes.

This is not game conditions but it is a serious bug if in game condition it cannot see the trivial mate until move 54 inspite of getting clearly higher depths.

I had never witnessed a game like this. Caissa 1.18 won (in the end) an ending with king + 2 knights against a king + pawn without tablebases at 40 moves per minute. I am not sure if the ending is perfect according to tablebases, but still quite impressive at 40 moves per minute on an old laptop.
NOTE; It is not just Caissa 1.18, Caissa 1.17 can do it as well

Something is clearly wrong with your stockfish because my stockfish in console mode not in game conditions play the right move and after the blunder see the mate easily instead of your stupid 0.00 at depth 38.

Maybe it is some bug because of the 50 move rule and I do not know

Something seems to be wrong in the game.
stockfish16.1 in console mode no tablebases and default small hash tables see mate score very fast in the position after 50...Ka3 at depth 23 after less than 300,000 nodes.

This is not game conditions but it is a serious bug if in game condition it cannot see the trivial mate until move 54 inspite of getting clearly higher depths.

I got exactly this in the colsole. I would say a blind spot resulting from prunning, instead of a bug. Clearly it is not doing a full width search. Also, maybe it functions differently in analysis mode than in game mode because there is time management to do in the game mode. So prunning may be happening differently.

NOTE; It is not just Caissa 1.18, Caissa 1.17 can do it as well

This is funny. Not exactly the same game, but similar ending! So looks like SF is missing something in the game mode.
