Chess boxing is a hybrid sport that asks competitors to do two very different things: out-think an opponent at a chess board and outfight that same opponent in a boxing ring. A typical chess boxing match alternates rounds of chess and boxing, so a competitor might be calculating a checkmate one minute and defending against punches the next. Yes, it's a real sport. Modern competitive chess boxing developed in the early 2000s, inspired by an idea that appeared in a French comic book. Since then, organized events, world championships, and several governing bodies have turned the unlikely combination into an international competition. A traditional chess boxing bout consists of 11 alternate rounds: six rounds of chess and five boxing rounds. The match begins and ends with chess. Between rounds, competitors get a short break — normally one minute — to change equipment. Boxing gloves come off when it's time for chess, then go back on when the fighters return to boxing. During the chess rounds, competitors may wear headphones to reduce outside noise and prevent them from hearing spectators discuss possible moves. A knockout ends the contest, as does checkmate. Running out of chess time can be just as decisive as losing a boxing round. The chess board and boxing ring may seem like opposite worlds, but chess boxing depends on mastering both. The winner has to keep thinking while tired, keep fighting while thinking about the unfinished chess position, and know that one mistake — whether it's a hanging queen or an unprotected chin — can end the match.
