Cross chess is a
chess variant invented by
George R. Dekle Sr. in 1982. The game is played on a
board comprising 61 cross-shaped cells, with players each having an extra rook, knight, and pawn in addition to the standard number of
chess pieces
A chess piece, or chessman, is a game piece that is placed on a chessboard to play the game of chess. It can be either white or black, and it can be one of six types: king, queen, rook, bishop, knight, or pawn.

In geometry, a hexagon (from Greek , , meaning "six", and , , meaning "corner, angle") is a six-sided polygon. The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°.

Hexagonal features
The cross chess board geometry has the same features as
hexagon-based chessboards; however, diagonals and ranks are defined differently in cross chess from
Gliński's and
Shafran's hexagonal variants, resulting in move possibilities more akin to standard
chess
Chess is a board game for two players, called White and Black, each controlling an army of chess pieces in their color, with the objective to checkmate the opponent's king. It is sometimes called international chess or Western chess to dist ...
. (E.g., a bishop has six diagonal move directions in Glinski's hex chess, whereas a cross chess bishop has four directions; a rook has six directions in Glinski's, whereas along ranks and on the cross chess board, it has four.) As with hex-based boards, three cell colors are used, but same-color cells highlight horizontal ranks on the cross chess board, not diagonals.

The diagram shows the starting setup. Special rank and diagonal paths determine how pieces move, as described below.

,
checkmate, and
stalemate are as in standard chess. However a pawn has no initial two-step option, and a rook can make a one-step diagonal move.
Piece moves
* A bishop moves along
diagonals – adjoining cells in straight lines 33.69 degrees from the horizontal. (Four possible directions.)
* A rook moves vertically along files (two directions) and horizontally (two directions) along
ranks – cells of the same color in a horizontal line. In addition, a rook may make a one-step diagonal move.
* The queen moves as a rook and bishop. (Eight directions.)
* The king moves one step as a queen. A player may
castle either (0-0) or (0-0-0). In each case the king shifts to the cell occupied by the castling rook, with the rook shifting to the cell on opposite side and adjacent to the king. Normal castling conventions apply.
* A knight moves in the pattern: one step on a file or rank, then one step diagonally outward. (Or vice versa: one step diagonally, then one step on a file or rank in an outward direction.) A knight leaps any intervening men.
* A pawn moves one step straight forward on a file, with no initial two-step option. A pawn captures one step diagonally forward.
