Re: Hard-Talkchess-2020 set, final release

Position #144 is probably not good enough. 3 moves are clearly winning.

Re: fun mates again

White, having a little advantage, just played bishop h4g3 probably thinking "let's disconnect the rooks", but this is a huge mistake ...

Re: fun mates again

I was intrigued enough to give a stronger try, but I think it will be very hard to drive to mate: FEN: r1k4r/1p1b4/p3pP1p/q7/1b2N3/6Q1/P1P3PP/1R1R2K1 w - - 0 1 ShashChess16-x86-64-avx2: Found 746 tablebases NNUE evaluation using nn-62ef826d1a6d.nnue enabled ... 45/75 1:05:33 294,676,841k 74,924k +4...

Re: Tournament with Honey, Corchess, Bluefish-XI and Crystal

I saw I made a mistake in engine config : I let the learning option for SugaR AI 2.20, Eman 7.40, and ShashChess17.1 :-(
I'll restart all the tournament.

Re: fun mates again

In this position, black has been to greedy and captured white rook on h1 with bishop. This will be the last mistake of the game ...
