Actually, I have a theory about this. I'm not "in the know" about this - I don't know the people who put TD-GAMMON together - but I have noticed the rather blatant appearance of cheating (program has three unprotected pieces, only way I *won't* hit it at least once is if I roll a 1 2, and guess what I roll). My theory is that this is a game that was trained via massive reiteration of playing against itself. During the course of that learning, it also "learned" the pattern to the pseudo-random numbers used to generate the die rolls. I understand that they probably change the seed from game to game, but depending upon the quality of the random-number generator, there can still be a repeating pattern, and that pattern might be built into the neural net (or whatever other algorithm is being used) that drives the computer play.
