The settings for the Chessmaster personality are believed to be the strongest
FOR ALL TIME CONTROLS AND ALL HARDWARE CONFIGURATIONS -- this last part is VERY
IMPORTANT to remember! CM8000's minimum spec machine is a PII-233 with only 48MB
of RAM. This is why the default personality only has a 1MB hash table. If
(knowledgable) users want to increase the strength for their hardware or
personal needs, then they can easily do so. The default personality is designed
for our default user, which is IN NO WAY representative of the typical member of
this board.

The ONLY personality setting that MIGHT improve play UNDER CERTAIN GAME
SITUATIONS with modification (other than the increasing the hash table size,
obviously) would be the "Selective Search" value. But, a value of 6 is best for
ALL time controls. I promise you, if you play a blitz tournament on a PII-233
with one personality being the default and the other having a 32MB hash table
with SS=12, the default one will be stronger.

People have confused the idea of strongest OVERALL with strongest FOR TOURNAMENT
TIME CONTROLS. These two are not NECESSARILY the same (although they might be --
nobody has proved anything either way).

Not only that, the SS setting is now even in doubt, as some people have recently
posted personalities that they feel are the strongest that only have SS=8. So,
in other words, there's absolutely no proof that the default settings (apart
from the hash table size) are not the strongest for tournament time controls.
