Your results still look very close to me . Some results show Yace ahead others
show Crafty.But the difference is never more than 10%. Your results seems to be
the same..

I benchmarked the so called K7 optimised version of Crafty18.12 and the one by
Eugene Nalimov on Crafty's FTP. Eugene Nalimov's version was behind by less than
1%. I doubt this translated to a great difference in strength.

And yes, I'm using a Athlon 1.4 Ghz computer
