How come ? It makes perfect sense IMHO : the conclusion ( and a very possible
one) is that it never existed - if this conclusion ( or any other one btw) is
reached it was useful to talk about it as a problem that obviously was of
interest to some ( they took the effort to post ) was there and was resolved .
People who think it is futile can keep away from the thread or ask for
moderation if they think it hurts their general reading experience. People who
have valuable information and feel like joining can provide it and help the less
knowledgeable. If someone has no new information, opinions or questions he can
still read and learn as long as interested.

I sometimes think this policy could be useful in some of the Deep Blue threads
also.

And I don't see I suggested anything that contradicts your statement anywhere
anyway - as I agree to your opinion.

Maybe your opinion is too extreme here ( or better your idea how such an
optimization might happen) . It might be more about ways of testing . An extreme
example : an author tests every major change he makes in 1000 1/0 bullet games
against GNU on his dedicated test computer . The engine might end up being
overtuned for being successful against GNU in the end - and it is conceivable it
will be stronger in Bullet games than at slower time controls.

I have read a few posts from chess programmers and beta-testers that explained
how they do their tests and I think some of them seemed to show something that
points into a similar direction but I am not the right person to discuss this.

I think some of the things Genius _seems_ to do might be better in blitz than in
longer games- for example the way it seems to evaluate some pawn structures ,
but I won't fall in the trap to talk about things I don't really understand and
won't go on .

OK - a sentence like this will somehow always be right - or will never be proven
wrong.

A question about testing the Palm Tiger added : I assume computer opponents on
68000 processors would be a fair match as this is a similar architecture ?
