Re: SPCC: Testrun of Lc0 42741 finished

... played at ridiculously fast time controls in a effort to gather 5000 low quality games in the shortest amount of time. I'll probably regret getting into this, but ... I assume the reason for using fast time controls is to get enough games to reach a certain level of statistical significance. I ...

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. I doubt that this position is a win for White. Black should simply avoid ...

Re: What's up with this endgame?

I just lost my first ICCF game since 2015, and I still don't know what happened. 8/K1k5/1p3p2/3p1pp1/3P1P2/PB1bP1P1/8/8 b - - 4 53 As others have pointed out, 53...gxf4 is a losing move: +148.42 54. exf4 Be4 55.

Re: Bin book adapter?

It seems Khalid (Eman's author) figured out how to find true paths so Eman can find its book wherever it is, but it's a closed sourced Stockfish so we don't know what's it doing differently (which an adapter would need to do, to work on the IC GUI). If he has provided you with a binary, I believe h...

Re: Bin book adapter?

All the GUI needs to do is pass along the path to the book file to Cfish. That may be what the GUI isn't doing. Is there a way to send those commands directly to the engine after it is loaded? I think I'd need to send it: setoption name BookFile value cfish.bin And then it'd use the book. But despi...
