I like your description of the second player's "mirroring" strategy... which raises a question: you indicate that the first player is prohibited from playing in the center on the *first* turn, but can he play there *after* the first turn (in which case presumably the second player would have a winning strategy, since he can't continue to mirror at that point)? The implementation suggests that this center move is *always* prohibited, is that right?
