No.175 – h#3 by Petko A. Petkov Non-standard pin-mates with blocks of mating piece – neutral MOA!  (JV)

Definitions:

MOA(MO): the Chinese knight, which is a Rider, moving along a bent line to the arrival square of a normal Knight, first diagonally then orthogonally. The MOA can be interfered with on the intervening square.

Nightrider(N): A Rider along a straight line on squares lying a Knight’s move away from each other.

 No.175 Petko A. Petkov Bulgaria original-26.11.2012   h#3            b) Kh4->g7       (5+8+2n)c) nMOd7->f1MOA d3, d7 Nightrider d8   Solutions: (click to show/hide)   a) 1.Sc7! nNe6   2.Sb5 nNa8!!   3.Sa7!  nMOxb6 # (4.nMOxa8? – impossible because Sa7 closes the MOA-line!) b) 1.MOf2! nNf4   2.MOg4 nNg6!! 3.MOf6  nMOxe5 # (4.nMOxg6?  – impossible because MOf6 closes the MOA-line!) c) 1.Sf6! Kg5   2.Sg4 nNg2!!   3.Sf2  nMOxe3 # (4.nMOxg2? – impossible because Sf2  closes the MOA-line!) Three surprising  Ambush-moves of the neutral Nightrider which pins the mating piece – neutral MOA! The paradox here is that the neutral MOA can’t capture the pinning nN because it is specifically closed by the black piece. Model mates with pinned neutral MOA. This combination is probably new.
