The world chess boxing championship was recently held in Berlin and Nikolay Sazhin of Russia took the crown when Frank Stoldt of Germany left his queen vulnerable and Sazhin forced him to concede. Kind of an intellectual knockout. Chess boxing is a new sport that alternates a round of chess with a round of boxing until one person either beats the other at chess or beats him senseless. Not that hybrid sports are anything new. The Olympics has the biathlon, which combines cross-country skiing and shooting a rifle, and the pentathlon, which includes fencing, shooting a handgun, swimming, horseback riding, and running. If chess boxing catches on it’s only a matter of time until more hybrid sports pop up, like checkers kayaking, poker golf, and Candyland UFC, which will alternate rounds of the board game with an Ultimate Fighting cage match.
