The great majority of Chessmaster owners (probably the same as the great
majority of owners of ANY chess program) have no chance at beating the program
at its strongest setting. So, finding the STRONGEST setting only applies to
those very few people (proportionately) who are titled players (or of similar
strength). The Chessmaster series (all platforms) sells about 300,000 copies
EACH YEAR, so it is easy to see that VERY few of the people who own a copy of
Chessmaster can challenge the Chessmaster personality.

BUT, be that as it may, the search for settings that are stronger than the
default is a valid one. The default settings for Chessmaster have really not
changed since CM5000 (and perhaps CM4000). Advances in processor speed and
cheapness of RAM may allow other settings to be better, that weren't better just
one year ago.

So, your work is not useless. My testing of your personality has shown that it
may be as strong as the default at blitz, and so far is shown to be stronger at
longer time controls. Of course, so far my testing has only been on a PIII-600.
If need be, we should try testing it on a low-end Pentium-II, to see if the
results still hold true on slower machines.

But there is always the possibility of including multiple "Chessmaster"
personalities in the program -- one for all-around play, one fine-tuned for
blitz, and another specifically for tournament time controls. This is not out of
the question.

So, therefore, I very much encourage your experiments and your testing, as with
anybody else who is in search of the "ultimate" Chessmaster settings! ;-)
