Re: PGN standard, its improvement and standardization

Principally i endorse your brave efforsts, but it won't work. The most you can hope for, is dying a peacuful dead, without anybody noticing. Why? Because there are a lots of commercial and private vendors who do rely on the pgn standard and if you are succesful in changing that standard -- even in a...

Re: Tactical Stockfish failure

Maybe not a tactical failure. SF just feels liquidating the pieces quickly is not a good continuation. After analyzing, SF wants to maintain pieces and maintan complexity of position. Good thing against humans and weaker engines. Why would you like to simplify quickly into a drawn endgame when you ...

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.

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.
