Siegfried Hornecker & Gilles Regniers, #5
Exactly one year and one day ago the following nice problem was published.
Siegfried Hornecker & Gilles Regniers
chessproblem.net, 13th February 2009 (also: Horizon 103, July 2009)
Mate in 5
It's my best composition so far, and Gilles Regniers ultimately managed to get it into a correct setting in February 2009. The original publication and solution can be found here:

Using officers something similar can be done with a rook, see:

This recalls me the very famous :
1.Qa8! [2.Sg4+ Ke4 3.Sdf6,Sç3‡]
1…Se6 2.Qh8+ Sg7 3.Qh1 [4.Qe4‡] B×d5 4.Qa1‡ model
1…Bf~,d2 2.Qe8+ Se6 3.Q×e6+ Kd4 4.Qe4‡
1…Bg5 2.Sg4+ Ke4 3.Sdf6+ Kf4 4.Sh5‡ model
1…Sf5 2.Qe8+ Se7 3.Q×e7+ Kd4,K×d5 4.Qe4‡

Meh. It must be a very near-lying theme when even I
did it (incorrectly) in my infamous INSELSCHACH years :-)
Still - just with pawns, that's a really neat setting.

Siegfried, you may really be pleased with this fine puzzle. Only an independent composer would decide on making such a controversial key. It seems to be an apt prelude.
An anonymous judge of WCCT would write: “Unfortunately, the queen doesn’t move clockwise”.
I know another similar witty puzzle.

Thank you Marek for quoting this, I like it too.
You can add the technical detail 4...Qf5 5.Qfxf7+! Sxf7 6.Qxf7+ Rd6 7.Be7#
But what relation with the previous problems ?

What a lovely problem by Jean-Marc and Jacques! I don't think the queen promotion is controversial in this problem, since two queens are an inevitable part of the mechanism.
As for the promotion key in Siegfried's problem: this is necessary if you want an all-pawn starting position. This is really what makes this composition different from other four-corner problems.

Marek, I don't understand what you want to tell me by the term "independent composer". The key is not controversial at all - it's necessary, as Gilles already wrote, if you want to have a position with kings and pawns only, which is the highest form of economy, used regularly by only few composers like Zinar, Grigoriev, Saletic, etc. - and the problem you posted surely belongs to the bigger masterpieces. The platzwechsel of white and black pieces is very admirable, even more since it is a platzwechsel of two white queens. The use of material is justified by the logical idea and obviously not possible without.
I especially like problems with kings and pawns only, but this doesn't mean I don't share a common taste. Many thanks for showing this!

I don’t know many valuable problems with a Queen-promotion key, thus, I think it was a compliment for authors.
