Three-check chess is a chess variant; it plays with the same rules as chess, with the addition that a player can win by putting their opponent in check three times.[1][2] Sacrifices are common and the opening can be filled with traps. Checking an opponent twice can create an advantage equivalent to captured material in the evaluation of a position. The game rarely reaches the endgame and is usually decided before queens are traded.
It is catalogued in David Pritchard's The Encyclopedia of Chess Variants where it is noted as being of probable Soviet origin, and that Anatoly Karpov was an "invincible" player in his youth.[3]
