BrainFish: Updated Avril, 15 2019

 

Times of big changes in the house of Brainfish. Doctor Thomas Zipproth has always been an inspiration to me since I've started to use his Cerebellum + Brainfish combo for playing against other computers and later making opening books myself. This time his site not only hosts a new Cerebellum, but also another version of it optimized for Leela Chess https://www.zipproth.de.

The news aren't ended here: the UCI interface of Brainfish has been enriched by a secondary book option. Looks interesting, although I'm pretty sure that a single good book is enough, but it definitely worths a try.

I still criticize the enabling of BestBookMove by default anyway, which has proven to give a lower performance.

Brainfish 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.

 

Lates version: BrainFish_190414.
