thanks, nice, but I like to replay the games in the replay zone, and there the last game is from round 3.

maybe at some point there will be an update to the zone too.

Was Brainfish using its opening book, while the other engines used no opening book? If the idea was to see the benefit of the book, brainfish with no book should also have been in the tournament. If the idea was to compare how engines play with a book, you could choose whatever non-private book you consider best and have all the other engines use that book. Maybe I'm misunderstanding what you ran.

Was Brainfish using its opening book, while the other engines used no opening book? If the idea was to see the benefit of the book, brainfish with no book should also have been in the tournament. If the idea was to compare how engines play with a book, you could choose whatever non-private book you consider best and have all the other engines use that book. Maybe I'm misunderstanding what you ran.

No, Clemens told me in the german css-forum, Brainfish played without its Cerebellum-Library. Then Brainfish is 100% identical to Stockfish.

Ok, thanks, that makes more sense.

It is a bit confusing. When Brainfish was announce here:

http://www.talkchess.com/forum/viewtopic.php?t=60934

It said " The book is contained in the exe itself, to demonstrate the unity of both. ". Has that been changed so it only uses an external book file?

Yes. Because the Cerebellum Library is updated very often and Thomas Zipproth decided, to separate Engine and Library, because he didnt want to do so much engine-compiles.
So, Brainfish has now the UCI-parameter BookPath, to load the Cerebellum Library. And without the Library, Brainfish is identical to a fast Stockfish-compile.

Thanks, that clears things up. Do you happen to know the final Brainfish that still had in internal book? It would use useful to know for people testing engines, since having a book is a huge benefit (even if the book is moves the engine would play anyway, it still saves a huge amount of time in the opening).

No, sorry. But it was some month ago...not much long after the release.
