So the only way to win in the end-game is to set up for a position where the are two possible moves to mate? There would never be any practical reason to resign I don't think.
> Checkmating loses the game, as it is always the top engine move. Rather than aiming for checkmate, players seek to force their opponent to make a top engine move. If a player only has one move available, that move will always be the top engine move, which loses the game.
