Piececlopedia: Mao-hopper

Historical notes

The Mao-hopper is a variant of the Mao, a piece known as the knight from Xiangqi and Korean Chess. The Mao is a popular piece in fairy chess problems; the mao-hopper is less known, but also in use in some problems. Where the Mao must pass an empty square, the mao-hopper must hop across an occupied square.

Movement

The mao-hopper is similar to the chess knight - it ends up the same distance away, but the difference is that it must jump over a piece. The mao-hopper is considered to move first one square orthogonally, and then one square diagonally (away from the starting square) to its destination square. The intermediate square must be occupied by a piece.

Movement diagram

In the diagram below, the White mao-hopper on d5 can move to all the squares marked with a black circle. It can also capture the Black mao-hopper, even though the Black mao-hopper can not capture the White one. Also note that the Black king is not in check.
