A short call on Crafty v24.0

Openings from Balanced-14.abk
Arena 3.5, Windows 8 64 Bit
Nalimov- and Gaviota 4p and some 5p tables

Code: Select all

Crafty 24.0    2638 - Booot 5.2.0                 2759   1.5 - 4.5    +1/=1/-4    25.00%
Crafty 24.0    2638 - Cheng 4_0.36c               2650   2.5 - 3.5    +1/=3/-2    41.67%
Crafty 24.0    2638 - Gaviota 1.0                 2719   0.0 - 6.0    +0/=0/-6    0.00%

Crafty 24.0    2638 - Quazar 0.4                  2743   2.0 - 4.0    +0/=4/-2    33.33%
Crafty 24.0    2638 - Shredder Classic MP 2012    2660   4.0 - 2.0    +3/=2/-1    66.67%

(no time losses)
18.0/42 = 42.9% and an Elo performance relative to CEGT 40/4 ratings of 2633.

Conclusion: Crafty remains the fine engine that it always was, and plays - like everyone of us - on it's level.

I guess huge steps forward would require a compromise with originality :mrgreen:

Contains a rather unique line-up with bBa1, wp c3 after 32.c3. Nice win.
