Three-check chess is a chess variant in which the winner is the first player to check their opponent three times. The game is more tactical than standard chess. Just as in chess, sacrifices are common and the opening can be filled with traps. Checking an opponent twice can create an advantage and can be equivalent to captured material in the evaluation of a position. The game rarely reaches the endgame and is usually decided before queens are traded.
