No.646 by Julia Vysotska – Imitator and nQ – mate by the one neutral piece in two phases! (JV)

Definition:

Imitator(I): Every time a piece moves an Imitator (or a set of Imitators) moves simultaneously in an identical manner. An Imitatorcannot move of itself. If an Imitator cannot imitate the move of a piece, the move is illegal. An Imitator may only pass through or enter an unoccupied square and cannot move off the board. Castling is imitated by decomposing into a King move followed by a Rook move.

Good idea to have a nQ to be the mating piece. It too is subject to the restrictions placed upon the bK. Alas for Black in the final positions the nQ can only move towards the bK – diagonally in (a) and horizontally in (b).

Very nice ODT – WK locks in the imitator to a corner, while also activating the neutral Q.

Nice problem. Julia thinks up a neat way of mating with a neutral piece! I have just one doubt… is the problem a miniature? I hope that experts will find an acceptable answer !
