Hasami shogi

Hasami shogi is a Japanese variant of shogi whose name means intercepting chess, and it departs from standard shogi by using only one kind of piece and by dropping checkmate as the way to win. In the most common form, each player sets nine identical pieces along their home rank on a shogi board, with the first player moving first; every piece slides like a rook, any distance along a rank or file as long as the path is clear. Capture follows the custodian method: sandwiching an opponent's piece between two of one's own along a row or column removes it from the board, and the game ends when one side is reduced to a single piece or fewer. A second, larger variant called dai hasami shogi starts each player with eighteen pieces spread across two ranks, introduces a jumping move, and is often played with plain Go stones instead of shogi pieces. Because the rules are simple to teach, the standard version is popular among Japanese schoolchildren even though it rewards the same kind of positional planning found in the parent game.
