Chancellor chess is a chess variant invented by Benjamin R. Foster in 1887. It features all the regular chess pieces plus one chancellor and extra pawn per side, on a 9×9 board.
John Gollon, in Chess Variations: Ancient, Regional, and Modern, expressed his belief that a variant like Foster's "will be the next step to the evolution of chess", because the addition of a single piece, the chancellor, a combination of rook and knight, "preserves a symmetry of power" on the chessboard with the queen, a combination of rook and bishop.[1]
The starting setup is as shown. All the standard rules of chess apply, but when reaching the final rank, pawns can promote to one of the usual pieces or to chancellor.
Chancellor chess was invented by Ben R. Foster in 1887 and was first published the same year in the St. Louis Globe-Democrat. Foster published a booklet titled Chancellor Chess in 1889, "dedicated to all liberal-minded chess players throughout the world".[2] An advertisement for a book by Foster on the game appeared in American Chess magazine in October 1898. The ad informed that the game was named after the new piece, the chancellor, with the board "enlarged to nine squares".[3]
