WCBO - official ChessBoxing Rules En | (scribd.com)

The basic idea in Chessboxing is to combine the no.1 thinking sport and the no.1
fighting sport into a hybrid that demands the most of its competitors – both mentally
and physically, yet which can be performed by easiest means.
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. In every round of chess the FIDE rules for a ´Blitz game´
apply, in every boxing round the AIBA rules apply with the following extensions and
modifications :
In a contest there shall be 11 rounds, 6 rounds of chess, 5 rounds of boxing.
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
