Three-check chess
Three-check chess is a variation of chess, in which a player wins if they check their opponent three times. Anatoly Karpov is said to excel in this chess variant (Pritchard 2007:83).
This chess variant is much more tactical than standard chess: sacrifices are very common, and there can be lots of traps in the opening. Two checks is already a big advantage and may be worth more than a piece in the evaluation of a position. The game rarely reaches the endgame – usually it is decided before queens are traded.
