My grandfather used to say "It is better to remain silent and be thought a fool
than to open one's mouth and remove all doubt."  My finger notes are quite
clear.  It is not my intention to play nothing but games vs a single program.
With the manual programs, this has never been a problem, as the operators need
a break after a few games.  But since Tiger is automatic, it became a problem
in that all I would see was games vs tiger.  That doesn't help me detect or
fix problems, and since I am writing this program, I reserve the right to test
it however I want to get maximum benefit from the testing.  I'd _much_ rather
play 100 games vs GM players (as it has the past few days) vs 100 games against
a single chess program.  If I thought _that_ was important I would simply buy a
copy of tiger and play the games offline rather than on a server.

My opinion, my choice.  I don't see why a "non-author" would want to take pot
shots at what _I_ want to do.  In any case, I am old enough to do what I want,
when I want, how I want...
