Subject: Opponent-modeling in computer chess

Hi,

I was wondering do someone know of an engine that do some opponent modeling? Has
it ever been tried? Is there paper/documentation about such an experimentation ?

I don't know to wich level it could be used, but it seem to me that a learning
strategie like the one used by crafty for it's opening book could be used on a
per oppenent basis. I think this could be proved really efficient against other
engines.

In particular, such an engine could learn not to be trapped in closed position
(so called anti-chess) against some player, but not change is opening theory
against other opponents. It could even learn to close the position against
stronger computer opponents (Am I dreaming?).

Opponent-modeling could also be applied to evaluation function weight tunning.
This, however, would require lots of games to be played. One could make it's
engine play against another engine X for some weeks and get an anti-engine_X
weight set.

What are your comments? Is there some documentation avaible about
opponent-modeling in computer chess?
