Hi,

after Doch, Spark and the very strong "new" engines from the Toga / Fruit family (Protector 1.31b and Cyclone xTreme Wrath) the next one. After my first results is Bison a very strong engine ...

Thinking after the first 20 fast games that Bison have the level from Glaurung 2.2 / Loop 13.6 (1 core, 32bit). I am not sure (perhaps stronger or not), but indeed very strong engine and also a very powerfull positional playing style.

Good news !!

I tested a little bit your Zappa Mexiko II setting with 40 in 10. Only 50 games but I cann't see bigger elo jumps.

THANKS for Bison !!

Best
Frank
