First learnt the sport called “chess-boxing” from 7/21’s Time Magazion. The opponents plays alternating rounds between 3-min. boxing and 4-min. of speed chess, until knockout or checkmate. As the official website puts it, it is the combination of #1 thinking game and #1 fighting game, (IMHO, chess is not the #1, China’s GO game is the ultimate summit of mental challenge and aesthetics).
This year’s tournament was held in Berlin. Ada Calhoun from Russia won the world champion by seizing the opponet’s queen, instead of punching him out. What an interesting game!
