‘The World Diving Chess Championships are like regular chess, except that it is held at the bottom of a swimming pool.
Players can only look at the chessboard and think as long as they can hold their breath.
When you make a move and get up, the opponent must dive and he can’t go up again until he makes a move.
Standard tournament chess pieces with weights are used and very strong magnets are used to keep all the pieces underwater.
An average match takes about an hour.
After playing games for a long time, their body temperature drops and they start to feel cold. This adds to the stress of competition.
Scores are calculated as 1 point for a win, 0.5 points for a draw, and 0 points for a loss.
In the tournament held in England, Michal Mazurkiewicz from Poland became the player who won the world championship by defeating his rival South African Alain Dekker in the final.
