I wouldn't personally describe Crafty as "second rate". However, whether or not you agree with that sentiment really doesn't affect the substance of my argument which is that, because Crafty is architected to run on multiple processors, and because it is well known that having extra computer power leads to a higher rating, it is a reasonable conjecture that if Crafty were run on a fast, multi-processor PC, it might well be as strong as the best human players. -g
