Definition & Meaning of "Grand Chess"

What is "Grand Chess"?

Grand Chess is a chess variant played on a 10x10 board instead of the standard 8x8 grid. In this version, each player has 20 pieces, including the usual pieces such as pawns, rooks, knights, bishops, queens, and kings, along with two new pieces: the marshal and the cardinal. The marshal combines the moves of a rook and a knight, while the cardinal combines the moves of a bishop and a knight. These additional pieces, along with the larger board, introduce new strategic possibilities and challenges. The goal of Grand Chess remains the same as traditional chess: to checkmate the opponent's king. The larger board and extra pieces add more complexity and depth to the game.
