Go up one level in this thread


The new GNU Chess takes about 2 1/4 minutes on a non-dedicated
SUN Enterprise-class machine. Includes the usual full leaf
evaluation (since exclusive pc/sq tables have been largely
discredited as well as the usual lazy eval.)

I don't see what point this test has since whoever can throw
the most iron at it "wins".
