this is very cool, but i feel like playing heads-up is kind of a completely different game from texas hold 'em w/ 3+ players. when you see ties over that many hands that just makes me think that both sides could be playing basically "optimally" based on on their cards and both players' chip stacks. on the other hand, i don't know that there is any "optimal" strategy once the game becomes three or more players.<p>sort of like how you could argue that the only numbers that matter are zero, one, and infinity-- this setup is firmly in the "one" camp, whereas normal hold 'em (and, presumably, many aspects of life) seem to be closer to "infinity". or perhaps i'm wrong and adding additional players would only scale the complexity linearly for Claudico et al. (no idea how it scales for human players).
