No.689 by Karol Mlynka – Non-standard mates with a white Royal fairy piece! (JV)

Definitions:

Back-To-Back: When pieces of opposite colors stand back-to-back with each other on the same file (white piece is on the top of black!), they exchange their roles. A pawn on the first rank cannot move. Any piece can make an en passant capture when it has got a role of Pawn by Back-To-Back.

Royal piece: Piece that executes a function of the King on the board.

Marguerite (MG): Moves like all simple hoppers (eagle + grasshopper + hamster + moose + sparrow).

Dummy (DU): A piece with no moves at all. It may be captured, gain temporarily moving ability by relay, or pushed or pulled around by other pieces if there are pushing or pulling pieces on the board.

Grasshopper (G): Moves along Q-lines over another unit of either color to the square immediately beyond that unit. A capture may be made on arrival, but the hurdle is not affected.

Eagle (EA): A grasshopper which pivots 90 o (to either side) at the hurdle.

Hamster (HA): Moves like a Grasshopper but deflect 180o on passing over the hurdle.

Moose (M): A grasshopper which pivots 45 o (to either side) at the hurdle.

Sparrow (SW): A grasshopper which pivots 135 o (to either side) at the hurdle.
