Re: a strange analysis by stockfish

I assume you do not like, that white cycles back to the root position once. I have briefly checked the source code and as far as i understand, this has something to do with the implementation of cycle detection in stockfish. Notice that there are no cycles targeting nodes under the root and that sto...

Re: Ortueta vs Sanz 1933

... To clarify, here's what I did and referred to as "forward/backward analysis". I had Cfish-dev search from the root position to some considerable depth. I then stepped forward through Cfish's PV from the root position to the end of the PV. I let Cfish search that terminal position, and it settle...

OpenMP for chess programming

I have a simple question: Would you consider to use OpenMP for chess programming? If i look a certain chess programs, this would be possible. Can you back up your opinion with facts? Thanks in advance.

Re: Bad Bishop win

In this position [d] 2r2rk1/p2qbppp/4p3/1p1pP3/1n1P4/5N1P/PP1BQPP1/R2R2K1 w - - 1 17 Leela played 17.h4!? This move never occurs to my stockfish@home, even 17.Kh1 would be preferred. After having established the thorn pawn leela violently opens the queen side with 26.a4!? [d] 2r3k1/3qbp1p/p1r1p1pP/1...

Fawn pawn win !?

Interesting game, worth studying i think. The superiority of black on the queenside is obvious, moreover white has the "bad bishop", which is not an active piece in any case. So why is white able to sacrifice d4? Stockfish itself will help us: [d]2r3k1/3qbp1p/p3p1pP/P2pP3/2rP4/5NP1/2nBQPK1/2RR4 b - ...

Re: which stockfish build to use

Open "Windows Powershell" or a command window, "cd <path to executables>" and try in turn "<name>.exe bench". If the command terminates immediately, you cannot use that build on your processor, otherwise wait until the test completes and check the line "Total time (ms): <number". Lower is better.

Re: You lost to a cheater

I see this regularily, maybe once in two or three weeks. My lichess rating flatters around 2250 currently, which is extremly bad considering that i am an FM. Back in the days, when programs like Fritz or Shredder dominated, you could spot a cheater in an instant, because they would flood you with in...
