Imitator moves are omitted - when replaying this one, don't forget to consider imitator moves too!

1.Qg4? zz Kd7 2.Rff6 etc. as in solution, 1...Ke6!
1.Qh4? zz Kd7 2.Rg5 K~ 3.Rff6 Kd8 4.Re6#, 1...Kc6!
1.Rff6! zz,
1...Kd7 2.Qg4 K~ 3.Re6 K~ 4.Qxf5#
1...Ke7 2.Qxf5! th. 3.Bd8 Kf8 4.Rg1#, 1...Ke8 3.Rg5 Ke7 4.Bd8#

Interested soul can find various letter themes in this #4, including change of continuation and Salazar, but the composition lacks strategy - it is only restricting of black moves.

To my surprise, judge John Rice included this problem in the award, commenting in a sense that changes after 1..Kd7 are awardable, but imitators are something like boring or schematical. Well, that's definitely true in this case!

Personal rating: C (upgraded from D).

(1...d2 2.Qa6#)

Reciprocal change with patrol strategy: in set play we have masked halfpin a1-h8-a8 and relevant moves cause patrolling of moved rook by Rg1. Key abandons hlafpin, but closes g1-b1. Black error this time is simple, but defence motive is interesting: masked patrolling of Rg1 by moved rook on line b1-g1. This way 1st rank is used in both directions. Unfortunately, white grasshoppers are not used thematically, they serve only as constructional trick. Can anyone work out this one with orthodox pieces only, keeping the described strategy?

Personal rating: C.

Triple echo of known Köko checkmate reached by use of black moose. Of course, I did similar helpmate with material KS+KS, but this way I was able to get only normal echo in two phases. Here everything fits perfectly...

Personal rating: B.
