Heh, I guess there are board states that are not possible to reach through a valid sequence of moves, but I guess otherwise it's not possible that games are more compressable by definition, since any valid board state could be represented as a sequence of moves. This does raise the question of the efficiency of reverse engineering a series of minimal moves for some board state.
