Hello Jason,
There is a possibility that 36 M hash may not help CM.  I have been doing some
testing at the default (1Meg) vs 16 Meg & 32 Meg.  At blitz (G/5) the default
won by 104.5-95.5 over the 16M & 32M combined.  I'm now playing some G/25
matches and it is still early (80 games) and the 16M/32M are leading 43.5-36.5.
So as I expected at longer time controls the bigger hash may help but at shorter
it is doubtful if it is much use.  Your time control is in between so may not
help or hurt.  I using 900 Mhz Athlons.
Jim
