No.291 by Julia Vysotska – Another battery play with my lovely Neutral Chameleon. This time with Grasshopper; and additional thematic shown by black Lion/Pao. (JV)
Chameleon: On completing a move, a Chameleon (from classical standard type) changes into another piece, in the sequence Q-S-B-R-Q… Promotion may be to a chameleon at any stage in the cycle.
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.
Lion(Li): Moves along Q-lines over another unit of either color to any square beyond that unit. A capture may be made on arrival, but the hurdle is not affected.
PAO(PA): Moves as Rook, but captures only by hopping over a hurdle to any square beyond.
