I have a new obsession. Evidently, it's getting popular in Europe.
The basic idea in chessboxing is to combine the #1 thinking sport and the #1 fighting sport into a hybrid that demands the most of its competitors – both mentally and physically.
In a chessboxing fight two opponents play alternating rounds of chess and boxing. The contest starts with a round of chess, followed by a boxing round, followed by another round of chess and so on.
A contest consists of 11 rounds, 6 rounds of chess, 5 rounds of boxing. A round of chess takes 4 minutes. Each competitor has 12 minutes on the chess timer.
A round of boxing takes 3 minutes. Between the rounds there is a 1 minute pause, during which competitors change their gear. The contest is decided by: checkmate (chess round), exceeding the time limit (chess round), retirement of an opponent (chess or boxing round), KO (boxing round), or referee decision (boxing round). If the chess game ends in a stalement, the opponent with the higher score in boxing wins. If there is an equal score, the opponent with the black pieces wins.
