This 40 square Chess variant is distinguished by its board. It's the regular Chess board set at 45 degrees, hence the name. The board was designed this way to make it 40 squares, but retain a symmetrical rectangular grid.

The pieces move as they do in standard chess, but seem to move obliquely due to the orientation of the board grid. There are some exceptions:

• there is no castling;
• the pawn moves along the diagonals, which are now straight, and may move forward, backward, and to the sides;
• the pawn captures along the orthogonals, which are now oblique;
• the pawn does not have the special initial move;
• the pawn does not promote.

This Chess variant was designed for the Chess Variant Pages 40 square variant contest.
