All I can tell you is from personal experience.  At one of the ACM events,
they had this thing running on a Sun in the back of the room.  I played it
several very fast games (human, not using Cray Blitz).  In the first game,
the game ended in a sort of 2 knights, with my bishop on c4, knight on
g5, and it didn't understand so it let me play Nxf7 forking Q and R.  When
we alternated colors, it played Nf3 Ng5 Nxf7 forking my queen and rook.
Of course, I played Kxf7 as the bishop wasn't supporting the knight.  But
it 'learned' that forking two pieces was good.  And it eventually figured
out that the knight has to be supported by a B, or else Bxf7 is no good.

I didn't see any great promise, but it definitely had a form of generalizing
learning...  that is all that I know, beside the fact that it did not have any
sort of alpha/beta search component...
