Actually, I guess Bill has it backwards: It must be relatively trivial
to check if the board state is symmetric, but it may be harder to create
a sequence of moves that breaks the symmetry or wins - on any symmetric
board. A simple pattern approach can be defeated by playing
(symmetrically) in the center where the pattern will have to match.
