Duel Shogi

Duel Shogi is a mini version of Shogi. Traditional Shogi is a 9x9 spaced board and we use 20 pieces per player, playing time usually takes one hour or so. It is very difficult for beginners and those who are unfamiliar with Japanese culture and Shogi rules.
I wanted to create a shortened version of Shogi for beginners. Duel Shogi will enable anyone to learn the basic rules by simple, repeat play. Each player starts with eight pieces, each of a different type. Thus the minimum board must be composed with 4x5 spaces.
