I ran 40 games at 300s + 3s:

Code: Select all

Score of Crystal 3.0 vs CFish 050920: 1 - 14 - 25 [0.338]
Elo difference: -117.2 +/- 63.3, LOS: 0.0 %, DrawRatio: 62.5 %

40 of 200 games finished.
Time control matters! :shock:

I tried Crystal 3 or actually Crystal 110920. Preliminary impression: It's much improved in tactical test suites - almost unbelievable good e.g. beating Houdini 6 tactical easily. Mate solving for fastest mate is worse than 080420 though. I tested with classical evaluation.
