Legan in 1913. It differs from standard chess by the starting position as well as by pawn movements.

Rules

The starting setup is illustrated. The game can be also played with the board rotated by 45° clockwise to make pawn movements easier to understand. There is no castling and no en passant. Otherwise, the rules of chess apply.

For example, white pawns promote on squares a5–a8–d8 (marked with white dots); black pawns on e1–h1–h4 (marked with black dots). Note that the pawns that start on d1, h5, a4 and e8 cannot promote without moving toward the center of the board via capturing.
