No.518 by Francesco Simoni – Meredith-Aristocrat with recently implemented Face To Face fairy condition! (JV)
Triton(TR): Marine piece operating along Rook lines: without capture moves as Rook, with capture – as Locust.
Nereid (ND): Marine piece operating along Bishop lines: without capture moves as Bishop, with capture – as Locust.
Locust(L): Moves along Queen lines only by capturing an enemy unit, arriving on the square immediately beyond that unit, which must be vacant.
Marine Knight(MS): Moves as Knight provided destination is vacant, captures an enemy on (1,2) by a leap to (2,4) – which again must be vacant.
Face to Face: When a white piece is just one rank below a black piece on the same file, they exchange their walk.

Aristocratic meredith with direct pin, preventive anti-check interference and pin mate. In the mating move, a NE becomes a CM for the FtF condition, so it would give check if the other NE doesn’t play before twice to interfere in B2 the check line. The first NE can’t leave its square, because it must allow the FtF in mate. To prevent the NE could defend the mate, it must be pinned in W1. Role reversal TRa6/CMf8 and NEf5/NEc4. (Author)
