If wK castling right remains, the only way to give White a prior move is to retract f7-f5, so ep would be on.
The key threatens (inter alia) 2. 0-0#/Kf2#, and both remain whatever Black plays, so the castling retro-justification for ep can never be disrupted.
R: 1. S~a3? a3-a4? blocks wT from retracting to home square if wK castling right remains.

paul: Since the wB couldnt leave c1, the captured piece on b6 is the promoted wPh2. If last black move was f7-f5, then h-Pawn captured four pieces to promote on d8, among which bRh8, impossible. Thus, the h-Pawn could only have been promoted from f7 and therefore d7-d5 remains as the last move. (2011-07-02)

'The Problemist Supplement': "The WCCT tourney of the time required #2s demonstrating changed self-blocks. The judge was Jeremy Morse and F [i.e. dieses Problem] was a clear winner. Set 1…Qxc4 2.Sf3; 1…Sxc4 2.Sc6; 1…Qxe4 2.c3; 1…fxe4 2.Rxd7 but nothing is set for 1…Kxe4. The strong give-and-take key forms a powerful battery. 1.Sxd7! (>2.Sb6) Qxc4 2.Qe5; 1…Sxc4 2.Rxd3; 1…Qxe4 2.Qc5; 1…fxe4 2.Se5 (switchback). This last mate also follows 1…Kxc4. There is no extraneous play and the wRd8 provides full value in both phases – a beautiful work. In his award Jeremy mentions that those few predecessors of which he was aware all suffered from certain shortcomings."

A.Buchanan: There is a good try here. It seems that there are two possible pawn histories. In the one in the given solution, wBef cross-capture, while wBah are waylaid (= captured by officers on their own original files). In the other, sBef cross-capture, while wBah capture to promote. In the latter case, could sS or sT uncapture a white officer which, following various parity-fixing adventures, unpromotes on b8, and then gives White the necessary tempi? The Black cross-capture would have been wBe2-6 sBf7-f6xe5 wBf2-f7 sBe7xf6-f5. I could imagine a situation with sSd8, sTc8, wDb7. Then R: 1. Db8-b7 a7-a6 2. b7-b8=D Tb8-c8 3. a6xSb7 Sc5-b7 4. Kg8-f8 Sd3-c5 5. Kf8-g8 Sf4-d3 6. Kg8-f8 Sg6-Sf4 7. a5-a6 Sf8-g6 8. a4-a5 Te8-e7 retropat. In this line, wPh3 was not waylaid, so can't get that extra critical tempo. a3-a4 is not possible because then wTa1 could never have escaped its home. (2022-01-24)

play all play one stop play next play all
Mario Richter: How is the ep-key justified here? (Perhaps some kind of AP?) (2010-06-15)
Gerd Wilts: The author's reasoning is 1. Sxc5? 0-0-0!, but if Black can castle, then White can capture en passant: 1. dxc6ep. But this if of course not correct according to the Codex. (2010-06-15)
A.Buchanan: The only problem with having this as PRA is that the part where ep & 000 are both off is cooked. That could be fixed by e.g. adding bPf6 & wPg7. But the composer is saying that this problem already works as AP, if we allow the try 1. Sxc5? (or equally 1. Se5?) to *prove* that 000 is ok, which implies that ep is ok too. (2022-05-24)

Henrik Juel: Black captured [Lf1] on f1, so Lg8 is promoted
Last move was not c7xd6, because White promoted c7-c8=L (d7xc8=L and promotion on e8 require too many white pawn captures)
and not e7xd6 or f6xe5, because this would require too many black pawn captures (2022-07-15)

White is missing one man, so last move was not a pawn capture
White pawns captured all six missing black men, so last move was not d7-d5

play all play one stop play next play all
The origins of this joke h#4, which utilizes Pam-Krabbe castling in a minimal form, was a mystery conjured by Per Olin, so far the only person who seems to actually know of it.

On the Internet, help was asked. On February 17, 2009, they sent a request for help on the Retro mailing list-ttps://pairlist1.pair.net/pipermail/retros/2009-February/002826.html This is what they said.

"Supercastling means castling with a promoted rook. Due to changed FIDE
rules it is nowadays illegal. It is said to have been invented by Max Pam, which inspired Tim Krabbe in 1972 (Hesse gives a different year) to compose a threemover including three different white castlings:

http://en.wikipedia.org/wiki/Joke_chess
_problem#Offbeat_interpretations_of_the_rules_of_chess

With the same supermove I composed a twomover (Stella Polaris 1975), Bengt Ingre has published a twomover (Mora Tidning 1993) and we have recently even seen an endgame study with this speciality.

Back in the good old seventies I was informed that there is a helpmate fourmover Ke1 pe7 - Ke8 (2+1) with the supercastling: 1.Kf7 e8T 2.Kg6 0000 3.Kh5 Kf4 4.Kh4 Th2#. Could be that as composer was mentioned Dawson, could be that it was somebody else. Could be that this is the first supercastling, could be that I have dreamt the whole problem.

Can anybody trace this problem?
Best regards
Per Olin"

It went unanswered. A decade later, on June 8th in the Matplus.net forums, they tried their luck again, but also to no avail-http://matplus.net/start.php?px=1582139891&app=forum&act=posts&fid=anti&tid=2302

Olin wrote: "Time wise this could have been inspired by the Krabbe problem. I have no memory of seeing that, but it could have been showed / mentioned in some meeting of the Finnish Chess Problem Society. What I vaguely remember is the following: (diagram) h#4

In an article in the magazine Suomen Tehtäväniekat, January 1994 I asked for author (Dawson?) and publication details, no response. The same question has been asked around one decade ago, probably here in Mat Plus Forum, no response. Question: can anybody trace the helpmate? - The solutions of both problems are obvious. - The chess rules of today say that castling is a move of the king and either rook of the same color along the player’s first rank; this was not the wording in the 70ies and earlier."

On January 4, 2021, a year and a half later, a reply was posted in the same thread to point exactly where they had asked a decade earlier (as aforementioned). Olin's reply, which currently stands as accepted, finally brings closure to this mystery: "Thanks! If the problem is nowhere to be found, then I must have dreamt it and attributed it by mistake to somebody else. Can I claim authorship?"

Now Per Olin has been credited as the author, properly and at long last. An exact source, if not the drifting memories of Olin's 1970's lost in time, is still quite the enigma, unless the 1994 reprint was the first time, which it likely may not be.

Preisrichter Petko A. Petkov in Mat Plus 2009:
A new development of the unique “Vielväter” position which has up to now over 1000 different modifications according to the combination of possible stipulations, conditions, form of the board etc. This new opus
favourably impresses with its great diversity of conditions in twins and especially with its long solutions.
Gunter Jordan: Entweder fehlt bei e) noch eine Bedingung (Köko??) oder die Lösung ist falsch aufgeschrieben. Oder beides. (2023-12-09)
