: invent new pieces with new moves.
Anybody ever played Martian Chess? Edgar Rice Burroughs designed a game using a 10x10 board with various pieces, each of which had a limited range of moves. Only the major pieces (Chieftan and Princess) could move in any way similar to the pieces on a standard chess board. All the other pieces had limits of beteen 1 and 3 moves, but the direction of motion was vastly imroved (IMO) from standard chess. Pawns (padwars) could move in any forward or lateral direction, one space only, including the diagonals. Fliers moved simliar to knights, in that they could jump, but were allowed one lateral or forward move and one diagonal move, making it possibe to move into a square directly adjacent to their starting point. I think the complete rules for Martian Chess are available at the back of Burroughs' (fifth?) book in the John Carter series: The Chessmen of Mars. Probably online somewhere, too.
