Hey, can you explain a little more in detail exactly how you got the computer 
to learn how you play so it gets better?  I've been toying with the idea of 
making an AI for my chess game for a while now, and that would be a big help. 
 Granted, chess is just a _little_ more complicated than tic-tac-toe, but... 
anything would help.  Thanks.

 Well, the problem with that is it isn't learning how to play, it's learning 
 how you play.  If you play enough games, it would work though.  The way I do 
 it has to do with backtracking to determine why it lost.  Quite neat.  The 
 other advantage to the way I do it is that you can port it to all sorts of 
 different games in just a few minutes.  The underlying logic to the computer 
 player remains the same.
