I tried playing gnuchess compiled with and without -DHISTORY on my SPARC 10.
With time limit 40 moves per 5 minutes it doesn't seem that the one with 
history heuristics plays any better than the one without.  As a matter of 
fact the one without history heuristics consistently looks at more nodes 
per second.  Does the performance cut outweigh the advantage of history 
heuristics?  Or is it only true with fast time limit?  Thanks in advance.
