Re: Strength limiting problems

Hi Michael, sorry, I don´t know how but an old bug has somehow managed to get into the current version of Spike. You can´t switch on elo reduction. Sorry. It should have worked with the uci parameter thus the Arena´s ELO limiting feature is the right way to use. The contempt value is the value Spike...

Re: Spike 1.4 is available

Hi Tom,

you have to enter some filename, if you want to use book learning. It doesn´t matter whicht filename you choose. Extension doesn´t matter.

Re: The "Secret" TT-move Singular Extension

Hi,

there has been some discussion here regarding this feature. If its helpful seems to depend from the chess engine. Some tried it wihout elo gain, some gained about 10-20 elo.

Re: Spike 1.4 is available

Hi Tom, sorry that I haven´t time to look at the feature and the code before. On my PC all works fine with book-learning. If it has no file, it would create one. Spike uses simply the extension that is set by configuration (file oder uci parameter). It might be .scbl. Please do not create an empty f...

Re: Spike 1.4 is available

Hi Tom,

I don´t think you are doing anything wrong. Spike should create an empty file if no file is present. I didn´t manage to take a look at the problem yet.

Re: Spike 1.4 is available

Hi Tom,

thanks for the bug report. Have to check the book learn feature. I never tried book lerning with limit strength. IMHO this doesn´t really make sence.

Re: Spike 1.4 is available

Hi Jouni,

using bitboard will take a development of a full new engine. I like the idea of magic bitboards. But all that work :-)

Re: Spike 1.4 running for the IPON

Hi,

it´s true. Stockfish is free and open, uses multi-cpu and stronger than most commercial engines. Thus as long as Spike is not much stronger than stockfish (would be happy if we could manage go be as strong as stockfish) it wouldn´t harm any commercial engine.

Re: Houdini 1.5 v Rybka 4 at long time control

Hi, there are tons of effects that may lead one program to play a certain move. First thing you should do is to find out if the engine is really sure about the selected move. Either use an engine feature (multi pv, ...) or just play the moves and let the engine analyse the resulting position. If the...
