Re: "combo" type reset to default value in Arena GUI

Actually, your engine is not UCI compliant. Certain options have a fixed value for <id>, which means that the semantics of this option is fixed. * <id> = Hash, type is spin the value in MB for memory for hash tables can be changed, this should be answered with the first "setoptions" command at progr...

There is a solution?
Report the bug to the Arena developers.

Re: What if the TT knew the number of moves

If the TT could return the number of legal moves for EXACT/ALPHA positions, what could that information be used for? What comes to mind is if we know there is only one move available, but not sure what to do with it. Ideas? My first engine set a bit in a position's TT entry if the search had figure...

Re: Developer tests of Stockfish need Stockfish 8 instead of Stockfish 7

So TCEC is absolute unnecessary thing. TCEC is as unnecessary as the game of chess. The results of TCEC are depend on the stroke of luck merely - at least under the strict scientific approach. The winner of TCEC is the TCEC winner. It was never the purpose of TCEC to determine the best engine. The ...

Re: Developer tests of Stockfish need Stockfish 8 instead of Stockfish 7

Of course the real problem is that you are confusing this web page with SF development: https://nextchessmove.com/dev-builds The NCM site has nothing to do with SF development. You are right, I addressed my post to wrong direction. But the the relative Elo loss of Stockfish is a real issue. No, it ...

Of course the real problem is that you are confusing this web page with SF development: https://nextchessmove.com/dev-builds The NCM site has nothing to do with SF development. Still, you can try to contact whoever runs that site and try to convince her or him to switch to testing against SF8 or SF9...

Re: Developer tests of Stockfish need Stockfish 8 instead of Stockfish 7

I do not know English very well, to understand how polite I am writing. Patience and politeness do not depend on knowledge of English but one's attitude. But what do you expect if you ask on Talkchess which is not the SF developer forum the SF developers to test against SF8 instead of SF7 when the ...

Re: whether or not a piece has moved and how many times

But if you ask me "how would you solve this?" then my answer would be: just don't zero the number for a piece when the piece is captured. Then when you uncapture it, the number is still there. If this is impractical, just save the number of times the captured piece had been moved in the undo stack ...

Re: whether or not a piece has moved and how many times

Well, that wasn't really the answer to my question now, was it? You question is "How did you solve this?" The only answer I can give is "I did not solve it because I have no need whatsoever to know the number of times a piece has been moved since the beginning of the game". As far as I can tell, th...
