  • Patent number: 5901957
    Abstract: A chess game variation is provided generally played by the traditional rules of chess, except that each player initially has eight "archer" pieces initially disposed on each player's third and fourth ranks on squares having the same color. Each archer piece moves in a manner similar to that of a pawn, but with several notable exceptions, including the ability to always move one square or two squares forward, and the ability to capture along the same file. The game markedly changes the traditional strategies formulated for the game of chess, and therefore provides a game having new mystery and excitement.
