Re: Weaker play with TT

I have no knowledge of javascript. My question is whether bestmove is returned correctly by the function that checks the hash table. In C language I use pointers when I want to return more than one parameter to the calling function, so I call the Read_Hash() function, pass it the &bestmove parameter...

Re: PGN validator

The joined_ tool allows to verify the games of a pgn file, for example I found that when passing games from a chessbase database to a pgn there are ambiguities with SAN. It warns but does not correct. joined -q -v126 file.pgn The pgn-extract tool allows you to correct some ambiguities and clean up s...

Re: Black Diamond Android App with NN Night Nurse 0.3

Thank you, I think I understand now, I didn't know such an app to make the remote work as a mouse. Although I have tried this app and the handling is not very good. It is really possible to find very cheap (about 25 dollars) android box Chinese that connect through hdmi to TV, these boxes can even c...

Re: EGBB (endgame bitbases) questions ...

Daniel creates the new dll files and he makes them compatible with previous versions. So you should be able to use the new versions with any engine that uses them. Surely it is advisable to use the latest version of his dll, so you can make sure that it works with any engine and also the new version...

Re: Are there chess programs to evaluate chess rating

I don't think that exists. The closest thing I've seen are applications that try to calculate the Elo of a game (only one game and can be pgn format). These programs calculate the error in each move made by the user and an engine that normally has used some version of stockfish. These programs usual...

Re: Comparing 4 move generators: 0x88 vs 10x12 vs 10x12 + bitboards HYBRID vs Pure MAGIC BITBOARDS

Btw, I have an idea to empower TSCP with magic bitboards (not sure if somebody done that before). This would make the movegen faster at very least, but evaluation also can be made faster if relying on bitboards. Will you personally be interested in having this sort of TSCP on bitboard "steroids"? h...

Re: WinBoard engines incapable of playing incremental clock

I am not sure I understand the question. I'm going to comment on an example, the TSCP engine. TSCP has a very simple time control management. When TSCP plays a time control such as x moves in y minutes and the time control is repeated, TSCP does not know how many moves are left for time control, so ...
