The game of sting is played as usual chess, but kings are scorpions, i.e., they have additionally the possibilities of grashoppers. Therefore the king moves diagonally any number of squares, but must jump and lands at the first square after the piece he jumps (either friendly or unfriendly). If that square is occupied by a piece from the opponent, that piece is taken, i.e., the king takes in the same way as it moves without taking.
 
Sting is an experimental chess variant. It was proposed in the British Chess Variant Society, and a brief article on the game by George Jelliss and Ian Richardson appears in the Autumn 1999 issue of 'Variant Chess'.
