The rules are fairly simple, albeit with a twist. The game itself is a normal chess game, except it is played in a swimming pool... at the bottom! Classic pictures of chess players playing on a floating board abound, but this is one variation that is far more challenging.
Bobby Fischer (pictured here in LIFE Magazine) was a fan of swimming and has many photos in a pool and underwater...
... and while there are famous images such as the one above, playing against Larry Evans in Reykjavik in 1972, they are played on the water, not under.
In Diving Chess, the entire game takes place underwater with the board, designed especially for this, at the bottom. The water is essentially chest high and each player takes turns diving under the water to make their moves.
Although informal games are held anywhere at anytime, the aficionados have put together a 'World Championship' each year for several years now. In 2015, the image above, it was held in Third Space Gym in Soho, London.
Each player can only think as long as they are able to hold their breath. Once you’ve made a move and come up for air, your opponent must dive and cannot come back up until they’ve played a move, and then it’s your turn to dive again…
This brings to fore some tactical aspects. Since the rules stipulate you must dive as soon as the other player comes up, one way to pressure the opponent is to play quickly, leaving them less time to recover their breath.
Another technical aspect is using weights. Even if you think spending 15-20 seconds underwater is no big deal, it can become a lot more challenging if you have to make an effort to stay under water. Even diving up and down, combined with constantly holding your breath, can soon become tiresome.
In the 2016 Diving Chess World Championship, Rajko Vutatovic explained that some of his rivals tried to pressure him by playing quickly. Imagine you held your breath for a full minute, calculating your move, and five seconds after you came up, still gasping a bit, you are forced to dive under again.
In spite of the competitive side to this all, it is ultimately still all about having fun in a pool with an original twist on chess
