Brian Godwin investigates a brand new sport
The original idea comes from a 1990s sci-fi comic book called Froid-Équator, in which the inhabitants of a distant planet compete in various games, including chessboxing. The first contests took place in 2003, and two years later Bulgarian "Tigertad" Titschko won the first European Heavyweight Championship in front of hundreds of cheering spectators. The champion beat his opponent in the ninth round of the chess match. The motto of the World Chess Boxing Organisation is ''Fighting is done in the ring — Wars are waged on the board''.
