Brainfish needs a Cerebellum_Light_Poly.bin book to play as Brainfish.

Without this book, it plays identical to Stockfish.
The book can be registered in your UCI Engine setup for Brainfish in the parameter BookFile.
This parameter must contain the full path and name of Cerebellum_Light_Poly.bin.

For example if you unzip the Cerebellum_light_160731 folder on your drive d:, BookFile must contain:
d:\Cerebellum_light_160731\Cerebellum_Light_Poly.bin

BrainFish can use two books parallel

Brainfish has a new UCI Parameter BookFile2. When playing with two Books, Brainfish first tries the Book set with UCI - BookFile. When the position is not found inside the first book, it tries the second book (if set) UCI - BookFile2 When playing with the Leela and Stockfish book parallel, the Leela Boook should be set as the first book

Another option could be to use a special Tournament book as the first book (BookFile), (which for example exploits some temporary weaknesses of other books or engines), and to use the Cerebellum Stockfish book as the backup book (BookFile2).
