What is the name of the sport in the photo?

Chess boxing, or chessboxing, is a hybrid that combines two traditional pastimes: chess, a cerebral board game, and boxing, a physical sport. The competitors fight in alternating rounds of chess and boxing. Chessboxing was invented by Dutch performance artist com Iepe Rubingh as an art performance and has subsequently grown into a competitive sport.

Chessboxing is particularly popular in Germany, the United Kingdom, India, and Russia. Chessboxing was invented by Dutch performance artist Iepe Rubingh.

Rubingh's idea to create a new sport fusing the two disciplines, chess and boxing, originates from the 1992 comic 'Froid Équateur', written by French comic book artist Enki Bilal that portrays a chessboxing world championship.

In the comic book version, however, the opponents fight an entire boxing match before they face each other in a game of chess. Finding this to be impractical, Rubingh developed the idea further until it turned into the competitive sport that chessboxing is today with alternating rounds of chess and boxing and a detailed set of rules and regulations.

The first chessboxing competition took place in Berlin in 2003. That same year, the first world championship fight was held in Amsterdam in cooperation with the Dutch Boxing Association as well as the Dutch Chess Federation and under the auspices of the World Chess Boxing Organization (WCBO) that was founded in Berlin shortly before.
