Hello Uri,

I was wondering if it has ever been shown that Comp vs Comp results don't
correlate well with games played against humans?

I don't think it has, so I would be of the opinion that a program that does well
against a known GM strength program(s) would itself be a GM class program based
on those results alone when playing humans.

I think the opposite is also true from what I have seen. I don't think there is
a program including crafty that is better against humans, but plays worse
against computers.
