But, I Wonder, Will It Work?**

Ser-h#5

Imitators* a3, b2, c3

Sol. 1. Kd1 (II b3, c2, d3) 2. Ke1 (II c3, d2, e3) 3. Kf1 (II d3, e2, f3) 4. Kg1 (II e3, f2, g3) 5. Kh1 (II f3, g2, h3), Kd4 (II f2, g1, h2) #

* IMITATOR. Colorless piece; cannot capture; moves only in dependence of other pieces, its move being simultaneous to every piece's move, parallel and of same length and direction. If a line piece's move is imitated, the imitator's path MUST NOT be blocked. Neither can the imitator be moved outside the board. If complete imitation is not possible, the respective move is illegal. This is even true for checks.

** Of course (this morning :), it does not work, because the BK is not under check (6. Bxh1 is impossible). Ok, my error could be useful for others composers.
