MR, der übrigens mit 4/II-III wertete, beschreibt das dargestellte Thema: jedem der vier wThemasteine ist ein Nachbarfeld des sK zugeordnet, welches er ganz allein deckt. In jeder Phase wird jeweils eines dieser Felder durch einen sStein geblockt, der unterwegs zufällig jene Themafigur schlägt, deren Deckungsaufgabe der in Forsberg-Manier sein Kleid wechselnde Stein auf f1 übernimmt. Der Superschnittpunkt T/L/N/(G) ist mir bereits aus einem feenschach-Serienzüger von P.A. Petkov bekannt, der mit einem ähnlich komplexen Zyklus einen Preis errang. Ich wüßte keinen Grund, warum es diesem reichhaltigen Hilfsmatt anders ergehen sollte.
EB: Die vom Autor gewohnten Linienöffnungen mit Matt- und Opferwechsel, hier mit Märchenfiguren garniert.

Gunter Jordan: Erstaunlich, dass solch ein Riesenproblem im Preisbericht nicht erwähnt wurde, nicht einmal im Nachspann des Berichtes, wo i. d. R. die Aufgaben stehen, die knapp gescheitert wind. Es muss für den Autor eine späte Genugtuung gewesen sein, sein Stück im FIDE-Album wiederzufinden. (2022-01-05)

Erstdarstellung (und bisher einzige Aufgabe) eines s#-TTC, in der alle Drohzüge durch einen Turm ausgeführt werden.
Gunter Jordan: Mir ist unverständlich, wie solch ein Meisterwerk nur ein Lob erhält. Ein komplettes TCC zählt zu den anspruchsvollsten und am schwierigsten zu realisierenden Themen im kurzzügigen s#-Bereich. (2022-09-18)

"This problem introduces a theme which, to the composer's and my knowledge and surprise, seems not to have been thought of before. Pérez Carballo (a Spanish chess player of around 2150 living in Glasgow - one of the first things he did there was to go to a library where he could see with his own eyes Barbier's 1895 Glasgow Weekly Citizen articles in which the Saavedra position was discovered - "I was almost crying of excitement as I turned the pages of the thick bound volumes until I got to the very colums") always felt attracted to the unusual in chess. He didn't play the Spanish but the Portuguese (1.e4 e5 2.Bb5) and composed some problems and studies with castling and en passant ideas, but this is his first publication.
The idea for this problem had "haunted him for almost a decade", but the best he had been able to come up with was a version with an inexcusably bad key; the capture of a Queen. Then one weekend, he decided to give it one last, all-out try. When he went to bed early Sunday morning, nothing had worked but after waking up, he realised he had seen the solution in a dream. It still needed a finishing touch - the a4 and b4 pawns had been absent - but when he added them, it worked.
1.Nxa4 threatening 2.Nbc3+ and mate. Black has two defences:
a) 1...Rxb1 when 2.Bd3 Rxa1 3.Rxc2+ Kb1 4.Nc3 is mate, and
b) 1...Rxc4 2.Nbc3+ Kc2 (2...Rb1 3.Bd3 Rxa1 4.Ne2 mate) 3.Bd3+ Kxd3 4.O-O-O mate
The switchback mate 4.Nc3 in variation a) and the model mate 4.Ne2 in b) are nice, but 4.O-O-O mate in b) is the central idea of the Belén Theme: in a direct-mate, the Black King starts at c1 and is mated by O-O-O.
But why Belén theme? Pérez Carballo sent me his problem on 17 July, because on that day it was 5 years ago he met his "other passion outside chess", his partner Belén - the Spanish form of Bethlehem. He dedicates his problem to her, and names the theme after her, wondering if ever before a chess theme has been named after a loved one.
So far so good, but there could be two reasons he's holding his breath now. A reader (Hanspeter Suwe for instance, the editor of the castling magazine König & Turm) might know of an earlier Belén problem - and a composer might be inspired to make a better Belén, either improving on this setting, or creating an new one. Pérez Carballo does realize his problem is not the perfect rendering of the theme. For one thing, the ideal Belén would be a three-mover. The flight-taking key is not very good; a black piece on b1 would conceal the solution better (but then it would have to be a four-mover) and he did not manage the Meredith form - 12 pieces or less. But the Pa3 is needed to stop 1.Na3+; the Pa4 is needed to stop 1.Nd2+ Kb2 2.Rb1+ Kxa3 3.Rxb3 mate, and the Pb4 is needed to stop 1.Nd2+ Kb2 2.Rb1+ Kxa3 3.Rxa4 mate.
But he did create the first Belén - nobody can take that from him."

James Malcom: This is the problem on Tim Krabbe's site that sparked the world wide chess phenomenon known as the Belen Theme and the problem that named the theme-https://timkr.home.xs4all.nl/chess2/diary13txt.htm (2020-09-20)
Henrik Juel: The thematic variation is correct
1.Sc3*a4 Rc2*c4 2.Sb1-c3+ Kc1-c2 3.Be2-d3+ Kc2*d3 4.0-0-0#
But the problem is very damaged by duals in other variations, e.g.
1... Tcc3 2.Ld1,Ld3,Sd2+,Sxc3+ (2020-09-20)

After a promotion to Queen, and a promotion to Knight, now we have a promotion to Rook.
****** Peter, thanks for Your interest in the Valladão-Belén!! :"
Post 7-"In his excellent # 5, Peter Hoffmann introduces important novelties in the VB field: The promotion move act in three different levels of significance (control of b3, of b5 avoiding to affect d3, and - not least- create a threat of mate in two in e4, allowing a consistent en passant part in real play) : 2.b8 = R is the most impressive single movement in the whole VB's history!
He refers to the Belén as a "motif". In the old Rebnora forum discussions Frank Richter alluded to an "ornamental effect". For Erik Zierke, the Belén condition arrive to become an obstacle ('Hindernis') for the more satisfactory expression in the Valladão field (in the same book we find others of Peter Hoffmann's creations in this field)."

James Malcom: Some months back, I managed to improve Hoffmann's P1380143. But has only been published recently alongside it, and ironically in the same month. The point here is that there is but a single solution. It turned out to be scarcely possible, requiring every White man but the queen. (2020-09-22)
