If all three castlings are legal, then the ep is on. So evidence must be accumulated from the two solutions. White 0-0 serves only in this retro role, eliminating 26 other candidate solutions.

A.Buchanan: There was a diagram error here. It should be bPd7 not bPe7. The existing diagram is vastly cooked with e.g. 1. Ke8 Kd1 2. Te8 Lb6#. WinChloe has the correct diagram here. (2022-05-24)

The idea is that the ep in one solution is validated by the castling in the other solution. Since no other solutions exist, there are no parasites which might "piggyback" off the proof given by the castling solution. This is not PRA: both solutions have the same history with both castling & hence ep legal.

This is not PRA: both solutions have the same history with both castling & hence ep legal.
Mario Richter: How is the (AP) to be interpreted here? Is the intention as follows: Since in solution 1) White castles, Black is allowed to capture e.p. in solution 2)? (2011-05-28)
Henrik Juel: It seems to be an unusual situation, not covered by keywords like AP or PRA.
If last move was c2-c4, both solutions work; if not, there is no solution, because White may not castle.
(In the second solution, Kxc4 should be Kc4). (2011-05-28)
VL: This a generalized type of AP, which I call "consolidate AP": both solutions are considered as parts of one complete solution. However the order of both parts is significant. I know two similar problems: P0003437 and P0003186. (2011-06-01)
A.Buchanan: @Valery: I've started to classify all the AP problems in PDB. This and its kin are "Type Petrovic - cons" (standing for consolidated, but there's only a limited number of characters for a PDB parameter). I truly hope that the theory in the end will not have this as a special case, but rather is part of a more general pattern.
It's not just that PRA & RS each scales up within its own paradigm to handle seamlessly very complex collections of conditional move dependencies. They also scale *down* to handle situation when there is just one conditional move, or even zero conditional moves. And when n=0 or n=1, PRA & RS are in complete agreement. This is the kind of robust seaworthy behaviour we need if are going to set sail in the stormy seas of fairydom.
But small steps. The first thing is to classify all the problems in PDB into buckets, to find out what we have. I doubt there are 37 categories, so will probably need the results of your scholarship too. (2022-02-17)

Der 'Vorwärts' erläutert die Lösung: "Der erste Zug der Lösung ist: 1. Le7-d6. Hierauf hat Schwarz die Antworten:Lxd7,Lf7,Kxd6,Kf6 und Lg6. Jede dieser fünf Möglichkeiten gibt zu einem anderen Zweizüger Gelegenheit. Und zwar wie folgt:1......Lxd7; 2.e5,L~; 3.Te7#. Oder 1.....Lf7; 2. d8D (macht eine Dame),~; 3.De7# Oder 1.....Kxd6; 2.dxe8T!, (macht einen Turm!....Bei jeder anderen Verwandlung würde das erforderliche Mat im nächsten Zuge nicht zu erzwingen sein) 2. ...

Die Idee des Problems besteht darin zu zeigen, wann es unter Umständen vorteilhaft sein kann, bei einer Bauernverwandlung statt einer starken Dame sich eine schwächere Figur zu wählen, und zwar sollen alle 4 Möglichkeiten (D,T,L und S) aus einer und derselben Position entspringen. Da die Wahl der Verwandlungsart erst durch den betreffenden Zug von Schwarz bestimmt wird, kann die Verwandlung augenscheinlich nicht im ersten Zuge von Weiß geschehen. Da aber mindestens ein Springer (und auch diese Verwandlungsart soll doch laut der Grundidee der Komponisten dargestellt sein) in einer von anderen Figuren verschiedenen Distanz „Schach" sagt, kann augenscheinlich die Verwandlung auch nicht im letzten Zuge der Lösung (im „Schach"-Mattzuge) erfolgen. Die Verwandlung muß also zwischen dem ersten und dem letzten Zuge der Lösung stattfinden. Demnach ist klar, daß die interessante Idee des obigen Problems in einem Zweizüger gar nicht dargestellt werden kann! Die allerkürzeste Form einer derartigen Ideen-Darstellung kann also nur ein Dreizüger sein."

Historisch: Womöglich die erste Exzelsior Darstellung im direkten 5-Matt.?! \eb
Sally: Hier kämpft sich der w. Bauer d2, von der 2 Reihe mit Pauken und Trompeten bis zur achten Reihe, um sich dort in einen Springer umzuwandeln. Die s. Dame h1 nachtwächtert!
In manchen Aufgaben ist sie gar nicht abgebildet, soll wahrscheinlich die Lösung erschweren.

SP: This is not the earliest excelsior in a #5; see 155 p. 321 in Chess Nuts,
originally published as 23 Porter’s Spirit of the Times 7/ii/1857.
Initially attributed to “Q. B. M.” of Newberry, but this was later (28/ii)
changed to O. B. M., when a later original (No. 26) was sent in by E. E. G.

It is stricter for helpmates than other problems, and may need some creative extension for retros. It deliberately excludes legality. It’s an area which would benefit from automation: e.g. curators should not be put in the invidious position of deciding subjectively how much duality is enough to violate soundness for antagonistic problems where there is some latitude (2021-03-08)

Artikel von Petrovici zum "Thema Than" 03/2016 gibt als Originalquelle an: "Europe Echecs 10/1951"
hans: Counting problem

1. 0-0 Sd5 2. Sh8 Sxe7# ??
Black needs a tempo to get on move, and the only piece to do that is Th8, so 0-0 is illegal. (2010-06-20)
Mario Richter: The term usually used to describe this kind of problems is "Parity problem". The bRh8 might have been on h8 all the time, since the tempo move might also have been made by the black Queen, but in this case, the bK must have already moved, thereby losing the right to castle too.. (2010-06-21)
Ladislav Packa: You both are right. Black would be in this position made an uneven number moves.
This can be achieved by using Rook moves (eg Rg8-f8-h8), or by the Queen moves while she was still alive (eg Kf8-g8, then Qf8-e8-d8 and then the King back). But both possibilities preventing black castling. (2013-10-04)
A.Buchanan: Parity change could also be achieved without triangulation by e.g. SxDe8 after the black queen has moved once (2022-03-15)
