“ The chief difference between chess and Shio-ghi is that in the Japanese game a piece does not cease to be a factor in the game when it is captured by the opponent, but may be returned by him to the board at any time as a reserve; and, secondly, all pieces, except the King and Gold General, are promoted to higher powers upon entering the last three rows of the enemy’s territory. This possibility of utilizing captured forces against their former masters and the altering values of the different men render shio-ghi a very difficult and complicated game. ”
