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.

ODT. Meredith. An Imitator, guided by the nQ and wK, prevents a check by the nQ on the second black move, and activates it after the second white move. Block of the nQ and guarding flights of the bK are made by the block of Imitator by the wK and pawns h7/h2. (Author)

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 !

Thanks to all of you! I’ve found it’s not easy to compose with Imitator.. but I liked it!
I also thought if it is a miniature. From the inventor’s point of view it is not as Imitator was defined as a piece. Maybe it would be right to show pieces as (5+1+1n+1i) ?
