Chess Engines with Opening Book

Post by mephisto »

Besides BrainFish are there any other free PC chess engines that contain their own opening book!

At least half of them at a guess.

Of the 90 engines that I currently use, only the following 21 do not have their own opening book.

Andscacs, Booot, Colossus, Discocheck, Ethereal, Fire, Frenzee, Gull
Hakkapeliitta, Houdini, Ivanhoe, Jonny, Laser, List, MinkoChess
Protector, Rybka, Senpai, Stockfish, Toga, Wasp

At least Rybka, Stockfish, Booot and Jonny had an own opening book at several points in time.

I think my post was misleading, sorry.
What I meant to say was, are there any other PC chess engines that have an opening book within their .exe file.

Spike 1.4 (and Spike 1.2 - the last native linux version) both have an internal opening book.

CT800 has that. About 12,000 unique positions, 22,000 unique moves. Transpositions are recognised.

This is not really accurate.
The Cerebellum book used by Brainfish is external. It is not part of the executable. It is just an advanced book made by mini-maxing a huge pile of chess data.

It can and does get replaced frequently, and you do not have to recompile to replace the book.

It is a more sophisticated format than polyglot books (and the data is better than most polyglot books), but I still consider it to be rather primitive.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Spike's book can be disabled via the config file.
