Re: What's up with this endgame?

8/3b2k1/1p3pp1/3p1p2/3P1P2/P3P3/5KP1/5B2 b - - At depth 100/187 SF dev finally shows +2.96 with analysis contempt on (c=24 so real eval is probably around +3.2 is my guess). So this might just be mate in N from this position. Can you post the analysis? If somebody can win it is only white but we sa...

Re: What's up with this endgame?

Note that with multi-pv of 2 moves stockfish is clearly faster and it may be interesting to have a match between stockfish and itself with fixed time per move when one engine use multi-pv with 2 options and the second use only one option and I wonder if there is some interface that allow it. I do n...

Re: What's up with this endgame?

I think that a good test position is the position after gxf4 stockfish developement version even in a bad day without disabling null move pruning can find exf4 at depth 89 stockfish9 also can see exf4 with enough time on my slow computer. 8/K1k5/1p3p2/3p1p2/3P1p2/PB1bP1P1/8/8 w - - 0 54 Stockfish_19...

Re: What's up with this endgame?

I just lost my first ICCF game since 2015, and I still don't know what happened. At the end of 2017 I reached this endgame: 8/3b2k1/1p3pp1/3p1p2/3P1P2/P3P3/5KP1/5B2 b - - I analyzed it thoroughly and concluded it was an easy draw, as I couldn't find any progress for white. There were positions wher...

Re: What's up with this endgame?

(Between moves 50 and 60) Judging by the 0.95 scores here, at move 53 Kaissa thinks Stockfish blundered away the half point (quickly sees that 53..gxf4 is wrong) and this still draw: 8/K1k5/1p3p2/3p1pp1/3P1P2/PB1bP1P1/8/8 b - - Engine: Kaissa IV NoContempt (512 MB) by T. Romstad, M. Costalba, J. Ki...

Re: future of top engines:how much more elo?

If you put a lot of money then I am afraid somebody is going to cheat in correspondence games(meaning he is going to pay another player to lose).
