© Licensed to London News Pictures. 23/03/2013. London, UK. Chris Levy (R) and Matt Read compete in a bout of Chessboxing Grand Prix in Scala, London, Saturday evening 23 March 2013. The hybrid sport combines chess with boxing in alternating rounds. The winner is decided by a knock out or checkmate, whichever comes first. A full match consists of eleven rounds: six rounds of chess, each four minutes long, and five rounds of boxing, each three minutes long (four minutes under amateur rules).[4] The match begins with a chess round which is followed by a boxing round. Rounds of chess and boxing alternate until the end of the match.[1][5] There is a one-minute break between each round, during which competitors cool out and change gear..
