What is the shortest possible game of Shogi ending in checkmate? I have not found the answer on the World-Wide Web. Kenichi Futamura has sent me the shortest game I know of. If you find a shorter game, please write!
For other shortest games, see the November 2012 issue of Erich Friedman's Math Magic.
7. G*5b mate.
In this game Sente's moves admit no variation, but Gote's first two moves may be played in either order.
