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)

Definition:

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.

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: in (I) neutral PAO makes a first move to come to the position from where it can capture neutral NAO and to move in accordance with Take&Make condition to the position of anti-battery’s rear piece; in (II) neutral NAO makes a first move to come to the position from where it can capture neutral PAO and to move in accordance with Take&Make condition to the position of anti-battery’s rear piece. 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.

Beautiful modification of the earlier 342. Pity so many black pawns are needed to control the neutral Nao.

• Julia says:

Thanks! I agree about black pawns. But the good thing is that just two of them are cook-stoppers! No model mate in (I), but still I’m happy about this setting as it wasn’t easy to find positions for NAO, PAO, wK, bQ.

• S. K. Balasubramanian says:

Really a very good improvement of the idea of earlier problem.(342). Now all the pieces are well utilized in both the solutions. It is good to see that one neutral piece is capturing the other one and WK after capturing BQ and completing the T&M moves controls g7 & g8 differently.

Well done! Congrats!

Thank you! I also think that this one is technically better. And the initial setting here was more complicated to find, although it has only one pair of pieces reciprocally playing. Two pairs is the benefit of No.342.
After that I’m amazed how it is possible to have 4 pairs of reciprocally playing pieces as in No.343 by Vlaicu Crișan & Klaus Wenda !
