Grand Chess is a variant played on a 10x10 board with two additional pieces; the Marshall (which combines the movement powers of the rook and knight) and the Cardinal (which combines the movement powers of the bishop and knight). The setup has most of the pieces moved forward one rank from their "normal" position, with an empty rank behind that allows more freedom for the rooks and maneuvering of pieces.
