But I am not sure how I would make it 'play' such a game. IE if it makes move 31. XXX, and then the score drops was the problem with move 31. XXX, or was it with move 30. YYY? IE it might take back 31. XXX and try 31. YYY only to see that drop too... and then try another move 31 and so forth. It would be 'interesting' to make it work... Because this is another form of 'learning'.... ie figuring out where it screwed up and taking back _that_ move rather than taking back a random move.
