I do not know if relatively crafty is weaker in blitz. It may be interesting if people try to find x when Fritz6(1 minutes) has the same strength as Crafty19.01 (x minutes) It is possible to try to find it by doing a match of 800 games from the positions after 1.a3 a6 1.a3 a5,.... and finding x such that the result is the closest to 400-400) After that people can try to find based on similiar match if Fritz6(10 minutes) is weaker or stronger than Crafty(10x minutes). people can use other programs and they can use Fritz8 and I only suggested fritz6 because it was in the discussion.
