Three-check chess

From EverybodyWiki Bios & Wiki

Three-check chess is a chess variant; it plays by the same rules as chess, with the addition that a player wins 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.

The game 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][4] Although Pritchard does not mention what happens if checkmate is delivered before a third check,[3] major online chess servers consider this a win for the checkmating player.[2][1]


Play tips[edit]

When outlining basic tips for beginners, International Master Daniel Rensch recommended players avoiding leaving open diagonals to their king, being cautious of open files, not allowing consecutive checks, and being aware that the queen can almost always make a second check if allowed to make one.[5]
