Grand chess is a large-board chess variant invented by Dutch games designer Christian Freeling in 1984.[1][2] It is played on a 10×10 board, with each side having two additional pawns and two new pieces: the marshal and the cardinal.
Marshal The marshal (M) combines powers of a rook and a knight.
Cardinal The cardinal (C) combines powers of a bishop and a knight.
A superficial similarity exists between grand chess and an early version of the historic chess variant Capablanca chess because the same pieces and game board are used. But differences in start position, rules governing pawn moves and promotion, and castling make them significantly different games.
