Go up one level in this thread


I ran a 100 game match with f9 versus rybka bettas. 4 min 2 sec

It was
rybka beta 9b (Vasik says 9b is the same as  10)  59.5 - 40.5
rybka beta                                        58-    42

I also ran a comparison of rybka beta with rybka beta 10 in a no book
tournement.(openings were 1 as d4, e4, c4, and nf3). this was  25 min 1 sec
tournmenet

Rybka beta 9b/10   23-    40
rybka beta 1       24.5-  40

Could there a big difference between 10 and 10d? Your results suggest yes..but
what the heck did vasik change in the 12 hours between the release of 10 and 10d

best
J
