The cluster of tries: Kh2-g1-f1-e1-d2-...-e8 0-0-0 Td7 is 12 moves: just too long.
In the diagram, e.p. is not permitted because last move might be g3-g4. So first shift sK to h4. Following the e.p., check that wK does now have prior move: Kf4-f3. Now sK scampers to e8 where through consequent forgetfulness it recovers castling rights.

Henrik Juel: Solution: 1.a1S 2.fxg3ep 3.Kxh5xg6-f7-e8 7.0-0-0 a8Q#. Nice problem with open and hidden ep capture (exf3ep). (2003-04-28)
James Malcom: How is the key here justified? (2021-01-18)
James Malcom: I am still pondering. (2021-09-14)
Henrik Juel: James, I have forgotten all about this weird stipulation during the time since my last comment, and I don't know what I meant so say...
The definition of shc in the PDB is not complete; here is the Schwalbe definition:
Konsequenter Serienzüger: Ein Serienzüger, bei dem nach jedem Zug die Retroanalyse der Stellung neu durchgeführt wird (also ohne Kenntnis früherer Züge und Analysen). Beispielsweise wird eine Rochade wieder möglich, wenn König und Rochadeturm auf ihre entsprechenden Felder ziehen (weil in der neuen Analyse "vergessen" ist, dass beide bereits gezogen haben).
In english, something like
After each move the analysis of the position is done afresh, without knowledge of previous moves;
for instance, castling is possible when king and rook reach their original squares (e8 and a8), because it is 'forgotten' that they have already moved (2021-09-14)
Henrik Juel: You ask for a justification of the key, James; there is no need for justification, Black can do whatever he likes
In the position after 1.a1=S last move must have been g2-g4, so the ep capture 2.fxg3ep is legitimized
In the position after 2.fxg3ep last move must have been Ke3xPf3, with the double check being explained by exf3ep++; this is the 'hidden ep capture' I mentioned in my youthful comment (2021-09-14)
James Malcom: Thanks Henri! While the definition is incomplete, the reset each time is deducible from looking over shc problems. The justification here, however, was a level above me somehow. (2021-09-14)

Henrik Juel: Maybe the animation will work in part b also, if you remove 'a) nach Diagramm' (2021-08-08)
Mario Richter: Position b) was missing and was added now, so the animation should work now.

Part a) is clearly inspired by Loyd's P1059840, so imho the problem should contain some reference that problem (e.g. "after Loyd") (2021-08-09)

Verbesserung von Aufgabe H3382 „THE PROBLEMIST“ Juli 2010

Wir sehen in dieser Aufgabe folgenden Inhalt:
1) Erhalt weißer Masse (wBg4).
2) Beseitigung hinderlicher weißer Masse (wBe3 & wBe4)
3) Das Matt mit sKa4 ist nicht möglich, weil Weiß für das Mattbild einen Zug zu viel benötigen würde.

Des Weiteren enthält diese Aufgabe meines Erachtens, wie schon erwähnt, sage und schreibe DREI Weltrekorde.
Also:

Rekord Nummer eins:
Längster schwarzer Königsmarsch am Stück in einem orthodoxem Hilfsmatt = 24 Züge.

Rekord Nummer zwei:
Zuglängste Darstellung eines schwarzen Durbars in einem orthodoxem Hilfsmatt = 24 Züge.

Rekord Nummer drei:
Zuglängster Rundlauf des schwarzen Königs in einem orthodoxem Hilfsmatt = 21 Züge.

Die beiden ersten Rekorde befinden sich schon in der Originalversion, die 2010 veröffentlicht wurde. Der dritte Rekord (längster Rundlauf des schwarzen Königs im orthodoxen Hilfsmatt) ist nun auch noch hinzugekommen.

Wahrscheinlich ist diese Aufgabe auch schwer zu lösen, weil der Löser versucht, den Quadrupelbauern abzuräumen, damit sich Schwarz einen Springer erwandeln kann, vergebens …

Christopher J. A. Jones brachte die verbesserte Version als Einleitung der Hilfsmatt-Urdruck-Serie im März-Heft 2018, sehr ordentlich besprochen, in Englisch.

Official solution text: This and the following tasks are connected by the search of retrogame, in which the position on the diagram allows the execution of moves that reach the goal (a posteriori).
1...f:g6 e.p. 2.0-0-0 g:f7 3./e8 f:/e8s# - the only solution with e.p. on the first move, leading to mate, requires preservation of the right to castling of Black. The problem is to prove that the position in the diagram is legal, provided that Black can castling and the last move was Black's g7-g5.
White's balance is closed: 11 + h:g3 + d:c2 + c:d + a:b + a-w! = 16
Black's balance closed: 14 + e:d3 + d:e4 = 16
Retro game: -1...g7-g5! -2.oh1-g2 +h3-f1 -3.me7-d5 +f1-h3 -4.mg6-e7 +h3-f1 -5.mh8-g6 +f1-h3 -6.h7-h8m +h3-f1 -7.h6-h7 +f1-h3 -8.h5-h6 +h3-f1 -9.h4-h5 +f1-h3 -10.h2/h3-h4 h4:Xg3 and the position is released. X is knight, bishop, or queen.
Retropositional play of the white knight and black bishop provides the possibility of ep. wPa2 is waylaid on the a-file. Example realization: 1. a4 d6 2. a5 Lh3 3. g4 Sc6 4. Ta3 Sxa5 5. Tg3 Sb3 6.

Author's solution from Problemas reprint 2022: On previous occasions we have already dealt in these pages with the ep convention, which establishes that, for the first move in a direct problem to be a capture ep, it must be possible to demonstrate by retro analysis that the last move was the double pawn jump.
It may happen that this demonstration is subordinate to the fact that a certain castling right is preserved. In this case, for the ep capture to be legitimate, in the subsequent direct game castling must be performed, which will conclusively prove that the en passant capture was possible. The codex states that, in these situations, the stipulation should indicate that the capture en passant will be justified by the subsequent castling, which is indicated by the term "a posteriori" below the diagram. Problem 1, which we use as an example, illustrates this concept.
It is a helpmate, and we see that the first move is made by White. And, indeed, for checkmate to occur, the capture at the passage of the black pawn on g5 is necessary. There are several continuations that allow Black to checkmate, but we must not forget that Black must castle during the process and it is here that the solution becomes unique: 1...fxg6 e.p. 2.0-0-0 gxf7 3.Te8 fxe8=D# (in helpmate notation).
But problem 1 is mainly an exercise in retro analysis. We must show that, if Black maintains the castling right, his last move was ...g7-g5. Let us look at the balance of the pieces. There are 14 black pieces on the board and the two missing ones can be shown to have been captured with c~d (= "cxd & dxc") or d~e. Five white pieces are missing and were eaten as follows: the a2 pawn was eaten on its file (if Black keeps his castling rights) and the other four pieces with hxg3, axb, d~e or c~d respectively.
We must realize that to open the cage at the bottom we have to retract ...hxg3, but this is not going to be possible until the white pawn on the h-file has moved back to the origin. To do so, we must retract the following moves: -1...g7-g5! -2.Ah1-g2 Ah3-f1 -3.Ce7-d5 Bf1-h3 -4.CSg6-e7 Ah3-f1 -5.Ch8-g6 Bf1-h3 -6.h7-h8=C Ah3-f1 -7.h6-h7 Bf1-h3 -8.h5-h6 Ah3-f1 -9.h4-h5 Bf1-h3 -10.h2/h3-h4 h4xXg3 and the tangle unravels. There is a retro opposition between the white knight and the black bishop and, since the white knight must pass the g6-square to unpromote, if this square is occupied by the black pawn (in case the last move would have been -1...g6-g5), essential time is lost, and the reader can see that the cage cannot be opened. Thus it is demonstrated that, if Black retains his right to castle, his last move was -1...g7-g5 and, therefore, White can capture ep.
A.Buchanan: Sketch of solution: 7 units missing. Black captured axb & hxg. In addition there must be captures onto c,d&e files. These can't all be by White, so one was by Black which by file parity implies a 4th capture by a black pawn, but not a 5th. The other cde capture was by White, which implies another to cross-capture with. So WbcBde or WcdBde or WcdBef or WdeBbc or WdeBcd or WefBcd. But bc & cd can't cross-capture alone. So WcdBde or WdeBcd, I'm not sure which. wPh promoted, so can't retract h4xg3 any time soon. wPa was waylaid on a-file by some Black officer. The position must unlock by uncapturing wSh8. (2022-02-18)
Henrik Juel: White pawn captures: e2xd3 and d3xe4
Black pawn captures: a4xb3, cxd, d3xc2, and h4xg3; [Pa2] was captured by a black officer
The retroplay could be
R: 1... g7-g5 2.Lh1-g2 Lh3-f1, wSd5 unpromotes on h8 and the pawn retracts, while the black bishop pendulates on f1 and h3, 9.h4-h5 Lf1-h3 10.h2-h4 h4xLg3 11.Kf2-f3 Lg2-f1 12.Kg1-f2 Lh3-g2 13.Tf3-e3 e3-e2 14.e2xDd3 Dd8-d3 15.Tf1-f3 d2xDc2 16.Dd1-c2 Lg2-h3 17.c2-c3 Tc3-b3 18.Tf3-f4 b3-b2 19.Le5-g3 a4xSb3 etc. (2022-07-04)

[Fussnote MD: Laut WINCHLOE und Christian Poisson gibt es eine Inkorrektheit: 14.Ka4 Lxd5 15.Kb5 Le6 16.fxe6 f7 17.Kc6 f8D 18.Kd5 Dc5#. In meinen alten Unterlagen fand ich, dass die Auffaserung der Lösung im 14.Zuge von den Autoren gewollt war. Sei es wie es sei: Wir haben nun eine korrekte Fassung der Idee gebaut in exakt 20 Zügen, die demnächst in PROBLEMIST UKRAINI als Urdruck erscheinen wird. Da Co-Autor SBD nicht mehr befragt werden kann (uns antwortet er seit fast sechs Jahren nicht mehr ...), sollten wir also die Sache auf sich beruhen lassen und mit dem H#20 findet sie dann auch einen der Idee gebührenden guten und schönen, „wohlverdienten“ Abschluss.]
Frank Richter: Das sind sicherlich 2 Varianten, 2009 einen derartigen Cook zu übersehen, halte ich bei den Autoren für ausgeschlossen. (2020-09-16)
Mario Richter: unterm Diagramm steht "C+", bei den Lösungen sind beide Varianten aufgeführt, allerdings fehlt bei der Forderung die Angabe "2 Varianten" (wie würde das notiert werden?!), auch in den nachfolgenden Ausgaben keine Korrektur/Präzisierung;

Auch die Echomatts sind verbindende Elemente dieses vorzüglichen Zwillings.“ (GJ) So richtig als Echo würde ich die Matts wegen der verschiedenen Blockzahlen nicht ansehen, aber sei es drum. KHS sieht „Mustermatts, Exzelsiormärsche, schwarze Opfer, schwarze Turmverwandlungen. Die umgewandelten schwarzen Türme blocken je ein Fluchtfeld. Alles ist so ähnlich schon dagewesen (in meiner dunklen Erinnerung). MRit wird sicher wieder genügend Vorgänger herausfischen.“ Auch HJä vertraut ihm: „Exzelsiormärsche und -matts des weißen Bauern und schwarze Umwandlungen für je einen notwendigen Turmblock in sparsamer Konstruktion; dass sich bei diesem populären Thema wohl einige Vergleichsstücke zitieren lassen werden, wird MRit vermutlich noch belegen“. Der äußert sich allerdings nicht dazu, sondern schreibt lediglich: „Wandert der Bauer links herum, wird der weiße König auf der rechten Seite gegen die Umwandlung des Blockturms abgeschirmt und umgekehrt. Dabei beeindrucktmich besonders die unscheinbare Zwillingsbildung“.
