BrainFish: Updated January, 15 2020



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.


Latest version: BrainFish_200108.
