In losing chess, captures are obligatory, and the goal is to lose all one’s pieces or be stalemated. This makes it perilous from the start: Of White’s 20 legal opening moves, 13 allow Black to bait him successively through 16 consecutive captures, losing (and winning) the game by force. The example above shows what happens if White unwisely opens with 1. d3. If he’d started with 1. e3, he himself could have forced a win — if he knew all the correct lines.
