grenv & Justaminute: You are correct that the king must be attacked and that I forgot to tell about stalemate. If the stalemate rule is needed, what about "When you don't have any move that would not lose the king, you are allowed to pass your turn, and if the opponent doesn't capture your king immediately the game is a draw" ?
