No.345 by Julia Vysotska – Anti-batteries, reciprocal play of neutral PAO/NAO, Take&Make with activity of the white King and black Q! (JV)
PAO(PA): Moves as Rook, but captures only by hopping over a hurdle to any square beyond.
NAO(NA): Moves as Leo, but on Nightrider-lines instead of Queen-lines.
Nightrider(N): A Rider along a straight line on squares lying a Knight`s move away from each other.
Take & Make: Having captured, a unit must immediately, as part of its move, play a non-capturing move in imitation of the captured unit from the capture-square. If no such move is available, the capture is illegal. Promotion by capture occurs only when a pawn arrives on the promotion rank as the result of a take&make move. Checks are as in normal chess: after the notional capture of the checked K, the checking unit does not move away from the K’s square.

This problem is partly based on the idea shown in my problem No.342(Julia’s Fairies – 2013/II).
Anti-batteries created with neutral PAO/NAO and a white King as a forward piece, where all pieces move to their positions using Take&Make condition.
Reciprocal play nPAO & nNAO:
Black Q on its first move creates a hurdle for neutral PAO/NAO for capturing of each other; and on its second move it is sacrificed to the white King with an “Attraction” motive – the wK moves by Take&Make and occupies a thematic square, creating an anti-battery as a forward piece. (Author)
