The 2014 Diving Chess World Championship will take place at 3pm on July 27 at the Third Space Gym in Soho, 13 Sherwood St, London W1F 7BR. Diving Chess is played like normal chess but with the board submerged in a swimming pool. Each player can think for as long as they can hold their breath, and must make a move before coming up for air (once one player comes up, the other player goes underwater only to emerge after making a move). The event will be a four round Swiss tournament so that everyone is guaranteed to play 4 games of Diving Chess.

If you’d like to participate in this year’s event, please email to reserve you spot. The entry fee is £10. Here’s some footage from last year’s event:
