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.[2] An earlier version of combining chess and boxing was said to have taken place in a boxing club outside of London in the late 1970s. The Robinson brothers were in the habit of playing a round of chess against one another after a training session at their boxing club. However, no direct correlation can be made between the Robinson brothers’ chess playing and chessboxing.[3] The same goes for the Kung-Fu movie “Mystery of Chessboxing” (1979) as well as the Wu-Tang Clan's song “Da Mystery of Chessboxing” (1993).
