This version was really targeted to be 'solid' for the ICC tournament. Other versions _always_ have new ideas that are sometimes good, sometimes bad. I don't know how the current version stacks up against commercial program on equal hardware, but in the past, the general testing approach of others was to compare a released version of a commercial program vs one of the many experimental versions of Crafty. With the expected results. It is easy to judge a book by the cover. But it is often wrong... Crafty may well still get smashed by the commercial programs on equal hardware. But on my quad, it is _very_ dangerous when it is playing solidly rather than in a test mode... > >This is written before I know the results from our testings, but I think Craftys >results are going to surprise many people.

The difference is about 30-35 %clockwise.
