I do this with early versions just to get a quick read on how it is doing. If you rember, when I asked you earlier about where you thought Crafty was at it's best you effectively said to try anything I wanted. I've tested Nimzo vs Fritz and Junior and they seem to play about as close at G/10 as they do at 40/90 with maybe Fritz being better at G/5 or G/10 than the others. Anyway I moved the time up to G/25 and so far Crafty is leading Nimzo by +9 -6 =7. That's quite a turn around from 25-7 favor Nimzo. I've got the Tablebases working now. I have to look over the games and see if the tablebases have made much difference. Do you have any stats on how much better Crafty plays with tablebases?(ELO difference) Jim Walker > > >> Of course Crafty >>is playing without it's opening book.
