can black wib this?

Post by Uri Blass »

The position is from a game of Capablanca.
The white bishop is out of the game so I expected to see a winning score by stockfish but stockfish does not see a winning score and -0.57 is not a winning score.

I wonder if stocckfish is wrong or if white can save the game.

FEN: r4rk1/ppp2p2/3b1q1p/2p1p1p1/4P1b1/3P1NB1/PPP2PPP/R2Q1RK1 w - - 2 13

The white bishop is out of the game so I expected to see a winning score by stockfish but stockfish does not see a winning score and -0.57 is not a winning score.

I wonder if stocckfish is wrong or if white can save the game.
Stockfish is right "thinking" he could save that game and proves it against Lc0, using 30 threads of 16x3.5GHz CPU, Lc0 had 2 and a 3070ti Nvidia GPU.
On the other hand with reversed colours it won with Black, here are the two games:

Peter, did you use a BT4 net (perhaps, BT4-1024x15x32h-swa-3400000.pb) with Lc0 v0.31.0-dag+git.a4877961 in that game?

No, ist was the BT3 2860M, that played at TCEC latest again too, sorry for not mentioning it in first place. I tried BT4 3400M with same compile and 3070ti too, it seemed to work about as good but in positional testing yet performed somewhat weaker at my trials with that GPU, regards

The white bishop is out of the game so I expected to see a winning score by stockfish but stockfish does not see a winning score and -0.57 is not a winning score.

I wonder if stocckfish is wrong or if white can save the game.

Game with reversed colours is in .pgn included as side line starting already at first (13th) move.

I totally missed the other game, what an embarrassment (Homer Simpson's moment)! I expected it in a separate PGN, not in the comments.

I see that both games are different since the very first move (c3 or a4), very early to claim where Lc0 went wrong. Thank you for the games and your time.
