Game Courier History


The PBM system is created by Fergus Duniho. It supports square and hexagonal boards in both ASCII and graphic formats. It enables email play of Chess variants by encoding the board configuration as FEN code, which it sends as an encoded URL along with other information, including a player's latest move.
