BrainFish: Updated March, 26 2020

 

I would like to spend a few words about Brainfish. After more than one year that I've created Stockfish Polyglot I've realized they aren't that different. They are practically equal, except that Brainfish has a Large Pages allocation to work faster with the hashtable that deactivates itself automatically when the RAM memory is too fragmented. The author says it would be recommended the administrator privileges to start the executable because of this, I don't agree: I guess this task is automatically made by Brainfish and if it didn't have the privileges to read/write the memory it would have simply crashed. Anyway Brainfish has the meaning to exist only if associated with its opening books, as Stefan Pohl is proving on his site; if I recall correctly the very first versions of Brainfish hosted the library inside the executable. Clearly I cannot host here the Cerebellum libraries as they are private work of Thomas Zipproth, so I will put a link with which to go on his website and download the opening books making part of the own Brainfish suite.

The past years I didn't put a link to his website because there wasn't a direct link to the download page and the site was written in German, but this doesn't happen anymore.

Brainfish has two slots for the opening books, so you should use as first Cerebellum_Light_Net and as second Cerebellum_light.

This combo will be tested, as long as Brainfish, in the next Goi 6.2.3 upcoming tournament, I am curious of what these two books can do against mine.

Brainfish is one of the strongest Stockfish-based chess engines available, extended by the general polyglot book format (.bin). There are some extensions in the Book Code for handling repetitions. In BrainFish the Book moves are only used in engine games, not in analysis mode. That means when BrainFish is playing moves which are in the Cerebellum book, it plays like StockFish regarding the evaluation, only at a much higher skill level.
Pondering is only active after the last move out of the book has been played.
