That sounds impressive!  An adaptive chess engine would be nice; most
people just give up if the computer whomps them once.  In case if you
didn't know, there is a series of articles about coding a chess engine on
gamedev.net.  They might help.

I am not entirely sure as to the internals of winboard.  When I mentioned
it, I was thinking of it as being a gui that supports user vs. user, user
vs. computer, and computer vs. computer.  I suppose that I see the AI as
the most difficult part to code.

I had it set on 10 sec. and it beet me too!  I would not say that it
crushed me; we had equal forces for most of the game.  I would be
thrilled to have an engine like that on my calc!
