Helpmates cited by the judge in the award of the 36th TT CCM

Soon we will have published the award of the 36th TT CCM. While I am editing it for publication, I can show you the problems that Abdelaziz Onkoud cited in his judgment. His remarks will be there, here you can find my short comments. Just a short reminder before start: 36th TT CCM was dedicated to orthodox helpamtes (h#) with all black moves made by king.

Abdelaziz Onkoud
10th HM Orbit 2012

1.Kf3 Rxe4 2.Kxe4 Sg5#

1.Kg4 Bxh5+ 2.Kxh5 Sf6#

Let's start description of this problem by noting reciprocal change of functions between Re5 and Sg6 - unblocking sacrifice for bK (Kniest) vs. pinning Rf5. Thene there is also reciprocal change of functions between Se7 and Sh3 - guarding vs. checkmating. There are also analogous lines of static wQ not existing in the initial position. As a result we get double-pin model mates. Quite deep composition, in spite of heap of black pawns.
