Three-check chess
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.
