Piececlopedia: Non-stop Equihopper
Historical notesThe non-stop equihopper is a variant of the Equihopper. Both the standard equihopper and its non-stop variant are fairy chess pieces that are regularly used in fairy chess problems. For instance, in 1999, a tournament to design fairy chess problems that use an equihopper or non-stop equihopper was held in Probleemblad, the magazine of the Dutch organization of chess problem composers.
The equihopper was invented in the first half of the 20th century, by G. Leathem.
MovementThe non-stop equihopper moves along lines in any direction, but must jump, and the distance before the hurdle (the piece that is jumped across) must be equal to the distance after the hurdle.
The non-stop equihopper can move to the squares marked with a black circle, and take the pawn on a3. Note that the non-stop equihopper can also move in directions that are not orthogonal or diagonal: e.g., in the diagram, it can jump across the king on b3 to c5.
