Re: kiwipete perft position

I have a strange scheme, I use the piece values as index into the bitboard arrays. I use the following constants: White = 0; Black = 1; Empty = 0; Pawn = 1; Knight = 2; Bishop = 3; Rook = 4; Queen = 5; King = 6; const white_pawn = White | Pawn << 1; const black_pawn = Black | Pawn << 1; etc. PieceTy...

Re: On-line engine blitz tourney October

Sure, but I'm not reading everybody's finger-notes. My expectation was that somebody joining the tournament with an engine is the original author of that engine, with maybe a few exceptions there.

Re: On-line engine blitz tourney October

Thanks for the info Joost, though Phalanx and Eichhoernchen have different authors. This is very strange because Belfish, Eichhoernchen and Phalanx were registered by the same person. According to CPW there were several different people working on Phalanx in the past. The last person working active...

Re: On-line engine blitz tourney October

Belfish is from the same author as Phalanx and Eichhoernchen.

His finger notes say:

1: StockFish derivative
2: experimenting with evaluation function, with small techniques for speeding up code execution, with compiling options ...
3: running commonly unattended

Another bug: "follow" does not show the game if the account you want to follow is presently playing a game.

--Jon
Thanks for notifying me, I will look at it. The Lasker software is filled with bugs.

Re: On-line engine blitz tourney October

There was an issue with sendmail tranferring messages to the external relay, it was difficult to find out what causes this, I finally switched to ssmtp, 'mailoldmoves' and 'mailstored' should be working now. At the moment we have about 23 registered accounts, on Harm Geert's server there used to be ...

Re: On-line engine blitz tourney October

The server works but seems to be missing a few little things. "rematch" command is not recognized. "eco" command does not work while observing, only if playing or examining. These are nothing major, though. The server is based on the public domain Lasker/Capablanca code, some commands and variables...

Re: On-line engine blitz tourney October

Some remarks: Initial ratings are set at 2500, nowadays an average engine has at least 2500 Elo. It might be good to play some games before the start of the tournament to get the initial ratings a bit more accurate. Channel 1 is the help channel, channel 64 is the computer-chess channel and channel ...
