Invented by Furugouri Akio(¥j°p³¹¶¯) in 1991, the Shogi variant is
played like standard shogi, including the drops and Promotion rules,
except the different move of pieces and the following rules:

1. The Pawn can be dropped to give an immediate checkmate.

2. All the promoted pieces cannot be dropped into the broad.

3. The King cannot move into the rank(row) where the opponent King
now stays.

I had implemented the Shogi variant.
