During the 16th annual Mind Sports Olympiad, a couple of bathing-suit dressed, goggle-wearing rivals are going to box off in the shallow edge of a pool on the opposite corners of the floating chess board.
A particular player will set a move. The other will promptly go over the board, expecting his opponent has not buried down any tactical albatross. After that, he will submerge.

Etan Ilfeld, the inventor of the diving chess and also, perhaps as you would expect, present world champion, realizes it’s not likely the year-old sport will at any time occur in the Olympics, yet he’s eager to enjoy the concept.
