In our laboratory, four types of computerised large shogi varients are currently used for playing games. This paper describes the design and development of the game server among the various functions of the computerised large Shogi. The communication protocol does not include piece type information, but only the position coordinates of the pieces before and after a move. If the coordinates do not change before and after a move, it is assumed that an Igui function has been played, and the position coordinates of enemy pieces captured by IGUI are added after the normal data. As there is no piece type information, this protocol is easy to apply to various types of large shogi varients and is highly versatile. It is also useful in that it is flexible to rule changes.
