SmallBrain 7.0 - released.

And with extra strength: 100 Elo stronger than its predecessor!

SmallBrain is a free open source chess engine under the GNU GPL 3.0 license.

Despite its name, this chess engine has quite a large and sophisticated "chess brain" :)

It can't be otherwise, since...

...SmallBran 7.0 is playing at over 3400 Elo

Here's what its author with the nickname Disservin, wrote about the seventh edition of his engine:


I am happy to release version 7 of Smallbrain!

As always the codebase is constantly evolving and many areas have been rewritten and cleaned up. I've also added the support of FRC/DFRC and an earlier FRC version is already on place 20 CCRL FRC! DFRC data has been included in the latest net as well.

Its becoming quite the bigbrain lately ; )


Lately, SmallBrain has been one of my most used chess engines.

I invite you to download SmallBrain 7.0, it's really worth it :)
