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)

James Malcom: I don’t believe that the great Fabel, with his keen eye, would have not seen such a simply cook as the taking of Black’s c5 pawn. I suspect that a Black bishop was on d4 but was forgotten placing the problem in the database, or it was a misprint. I am changing this problem to not cooked for now. However, someone should check the original source in the event I am wrong, which is always a possibility. (2020-03-15)
Mario Richter: Hi, James, there's indeed a black bishop on d4. Original stipluation: "h#48 (nicht exakt!)"

Joost de Heer: Stupid question, but won't moving Bh3 to g4 add another halfmove? (2023-01-30)
Henrik Juel: Yes, Joost, but this would make the solution even less exact
0... Lf3,Lh3,Lh5 1.g4 Lxg4 etc. (2023-01-30)
Joost de Heer: @Henrik: So? This is an attempt at a non-unique (exact is something else) h# length record, the level of non-uniqueness is irrelevant. And as James pointed out, adding Kg4-f4 will add yet another move.
Only possible cooks are when white starts with 1... Bh5 2. g4 Be8 (so not capturing Pg4) but I don't see how that could lead to a quicker mate. (2023-01-31)
James Malcom: I double-checked that myself, Joost, and found that going around for wPg2 actually takes far longer, which would be required any PxB action to take place, but that takes far longer than the normal solution. I know Olaf's Gustav would check, since it C+ the h#111. (2023-01-31)

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)

Durch den ep-Schlag beweist Weiß, dass der letzte Zug von Schwarz
e7-e5 gewesen ist. Die sGG können mangels Bock nicht gezogen haben
und hätten sK oder sT gezogen, so wäre die {\ooo} nicht mehr
möglich (Autor).
A.Buchanan: sGh8 seems useless as it merely eliminates the thematic retro tries. What am I missing? I wonder if the composer really understood the nature of AP...? (2022-03-22)

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

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.

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.

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.

Diese Realisierung eines sechszügigen Exzelsiors in Verbindung mit einer vollständigen Drohung ist eine gelungene Erstdarstellung. Dabei würde es schon in 5 Zügen zum Matt reichen, wenn der entfesselte schwarze Turm nicht auf a5 parieren könnte. Trotz der guten Darstellung glaube ich, dass das Thema noch Möglichkeiten nach oben bietet. Insbesondere bei Vermeidung von Nebenspiel würde der Grundgedanke an Übersichtlichkeit gewinnen.

Inhalt:
Meerane-Thema, Fünfte Form (Sauberer Reziprokwechsel-Meeraner): In einem Hilfsmatt mit zwei Lösungen führt Weiß den Schlüssel aus. Der Mattzug von Lösung I. wird zum Schlüsselzug von Lösung II. Der Schlüssel aus Lösung I. wird zum Mattzug in Lösung II.
Themafiguren: weißer König und weißer Bauer.
Hier findet die Thematik auf einem einzigen Themafeld statt (e8).
Zweimal Mustermatt.
Dieses Mal gibt es die Besonderheit, dass Weiß mit einer Bauernumwandlung arbeitet.
