What do you get when you combine physical fitness, aggression, strength with strategy, mental dexterity and logic? Answer: Chess boxing.

I kid you not. Yes chess boxing is real. The video below is not a spoof.

“A match between two opponents consists of up to eleven alternating rounds of boxing and chess sessions, starting with a four-minute chess round followed by two minutes of boxing and so on. Between rounds there is a one minute pause, during which competitors change their gear. The form of chess played is speed chess in which each competitor has a total of twelve minutes for the whole game. Competitors may win by knockout, checkmate, a judge’s decision or if their opponent’s twelve minutes of chess time elapses. If a contestant does not make a move in the chessround, he will be issued a warning by the referee and he must then make a move within the next 10 seconds.”

This leads to a very sweaty chess board with the occasional drop of blood on the white squares and a rook to the eye.
