Chessboxing
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.
