No.373 by Julia Vysotska – Parrying double check to the black King with the one black piece which simultaneously gives mate to the white King. (JV)
PAO(PA): Moves as Rook, but captures only by hopping over a hurdle to any square beyond.
VAO(VA): Moves as Bishop, but captures only by hopping over a hurdle to any square beyond.
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.

The main theme is parrying double check to the black King with the one black piece which simultaneously gives mate to the white King.
White N opens line for the black Bishop and is sacrificed to the black N to attract it to the the squares where it is sacrificed to the white VAO/PAO.
Reciprocal play of two black Ns:
