Despite having it’s own youtube channel, chessboxing is yet to take off. It has a cult following and has been televised enough times already, but it isn’t generating sponsorship on any level and remains subterranean for now. Admittedly, I can’t see what the attraction is as it appears so amateurish thus unentertaining. But anyway, here’s a sneak preview of something earlier this year, just perhaps it may float your boat.
