Problem 739: Abdelaziz Onkoud - Helpmate
abdelaziz.onkoud2(12.06.2016) The judge of the 4th Azemmour Tourney shows an original example showing the "Rope theme" of the Tourney.  Here the theme shows an interesting cycle of SB-BR-RS.

I'm sorry. Rodolfo is right: there is no cyclic Azemmour4 in Parrinello's h#2, just three pairs of thematic pieces (AB-CD-EF).
Also, compare to:

Medintsev's problem is nice with three selfblocks on g6!! Also matching play by B/W.

Both problems in #3 and #5 show that in PDB there some examples of Zilahi theme without labels.
The following problem is the most economical version of the Rope+Zilahi :
R.F.Zalokotskij and M.Kolesnik, Kudesnik 2009
4k3/4P3/4B3/1K1bS3/6s1/8/8/4R3 (5+3)

1.Sxe5, Bxd5 2.Sf7, Bc6# 1.Bxe6, Sxg4 2.Bf7, Sf6#
It is in the PDB without any label, of course there are other similar examples.

Here is the diagram to #9

Rope+Zilahi+Chumakov+self -block of the same square by different black pieces. A pleasant one.

Quoting Rauf Aliovsadzade:
Bonjour Abdelaziz,
Votre nouveau h # 2 est tr?s agr?able!
Et f?licitations pour la tourn?e gagner au Mont?n?gro!


Bonjour Rauf , Merci. C'est juste un exemple qui montre la forme cyclique ? 3 solutions. Je suis certain qu'on peut faire beaucoup mieux. Par contre , les sch?mas que j'ai mentionn? un peu en haut m?ritent des exemples concrets. J ai envoy? un exemple a Kaylan montrant une forme ? 4 solutions.

The work in #5 is much better, there is no comparison!
It won the first prize in the Best Problems IT 2006-2007 but the ranking has been changed after the rough forerunner(#15) was discovered. In any case it deserved the first prize, I think.
Also in my opinion any h#2 with cyclic Zilahi+"Stocchi blocks" ( no matter whether crude or refined) should be seen as anticipated by the Vitaly's version, and despite some additions as in the following:

RodolfoRiva - practice about the 4th Azemmour theme
K7/1p1r2p1/1P1ppp1s/3kS2s/2pP1P1P/1qp2SQ1/2P2P2/8 (10+12)
h#2 3 solutions
1.Qxc2, Sc6 2.Qe4, Sb4#
1.Sxg3, cxb3 2.Se4, bxc4#
1.dxe5, Qxg7 2.e4, Qxd7#

There could be one more comparison to the work in comment #5
Take a look at this

Valery had sent me this version via e-mail on may 31 but he has refused to publish his work due to presence of my h#2 as a forerunner.
I have recently got his 'Ok' to publish this problem here in the comments.

A Letztform, I guess

By the way, the works in comments #5, #15 and #18 show also Balbo theme

Astonishing version by Gurov!

So the discussion is more and more interesting. Waiting for the 4 solutions version by Abdelaziz (see #13), h#2.5 or more is the challenge but the FORMES IV, V, VI are not easy to achieve even in 2 moves.
