I have been playing chess since I was a child. I'm not really good, but I enjoy the game. Today I play against my seven-year-old son, who (still) has his troubles playing against me. How could it be otherwise. After all, I have decades more experience in this game than he does. One day, however, my son learned a new chess variant at the chess club called losing chess. In losing chess, the normal chess logic is turned upside down. The player who has lost all his chess pieces first wins. It can't be that difficult to lose your pieces, I thought to myself, accepted my son's losing chess challenge, and lost right in the first game.
