No.390 by Mario Parrinello – A very unique Miniature with exotic construction and play! (JV)
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.
Contra Grasshopper (CG): Moves like a G but in reverse: the hurdle must be adjacent to the CG, which may land anywhere on the line beyond.
LEO(LE): Moves as Queen, but captures only by hopping over a hurdle to any square beyond.
PAO(PA): Moves as Rook, but captures only by hopping over a hurdle to any square beyond.
NAO(NA): Moves along a straight line on squares lying a Knight’s move away from each other (as Nightrider), but captures only by hopping over a hurdle to any square beyond.
Royal Piece: Every piece that executes Royal function on the board. Every side can play with only one Royal piece when it doesn’t have its own King on the board.
