H.Juel: If Black may castle, last move was not made by Ke8 or Ta8, but by Pd5, so it was d7-d5, and hence White may capture en passant. 1... exd6ep 2.0-0-0 dxe7 3.Tf8 exf8=D,T# where the castling (belatedly) justifies the e.p. capture.
Not 1... exd6ep 2.Kd8? dxe7 3.Kc8 e8=D,T
AB: Another 120 retro tries (=60x2 due to tolerated dual promotion) of general form 1. exd6ep 2. T~ dxc7 3. T~ c8=D,T.

VL: The first AP-problem! Thematic illegal try:
1. ... exd6ep 2.Kd8? dxe7+ 3.Kc8 e8=T(D)#?? (2007-02-11)
Mario Richter: 46 years between this Problem and P1366663 - perhaps this was not Keeble's first AP-Problem?! (2019-08-29)
Ladislav Packa: Of course I know the idea a posteriori. But let my heresy be forgiven - I do not consider it logical. In this particular example, I consider e.p. for proof that black can castling - not vice versa. (2019-08-29)
A.Buchanan: Hi Ladislav. If ep is ok, then Black just moved a pawn with double hop. That doesn't stop Black having e.g. moved bK right at the beginning of the game. So you can't prove that Black definitely can castle this way. What am I missing here? (2019-08-29)
Ladislav Packa: Your statement is perfectly fine. However, the AP condition is usually interpreted as castling is evidence of e.p. However, the second party does not have to do castling - the possibility has already been demonstrated by the existence of e.p. (2019-08-29)
A.Buchanan: Hi again Ladislav. Please try again, I am obviously being very stupid. I don't understand how 1. exd6ep is any more indicative that Black can castle than 1. K~. (2019-08-30)
Ladislav Packa: Hi, Andre!
e.p. is just a result of the d7-d5 move. Black can castle only if it was the last move of black (even without wPe5). Therefore, it does not have the logic of joining the e.p. with castling. For example, ask yourself if black is allowed to castle in the position without wPe5. (2019-08-30)
A.Buchanan: @Ladislav: ep is not "proof that black can castle", rather it is a *necessary* condition for Black to be able to castle. The logical implication is the other way round. We can castle because of the optimistic convention, and because sPd might just have moved. Without wPe, there is no solution, but whatever White plays, Black can castle (2020-12-11)
Hans-Jürgen Manthey: was heißt hier Thematisch Illegal ??
Mir völlig wurscht ob ep möglich oder nicht, nach dem weißen Zug ist natürlich Kd8 möglich !!
also ist auch 1. ... exd6ep 2. Kd8 dxe7+ 3. Kc8 e8DT# eine Lösung, sonst müßte auf die erzwungende Rochade in der Aufgabenstellung hingewiesen werden ! (2020-12-11)
A.Buchanan: Can one tolerate “tolerated dual promotion” in Valladao? Well Valladao himself did, so it must be ok (2022-03-26)

1. Dc4-g8!
play all play one stop play next play all
Mario Richter: Cook: Schwarz hat keinen legalen letzten Zug (2014-05-25)
A.Buchanan: This is not a retro problem. If we grant Black first move, then 0. ... Txb7! refutes. It's just a technical oversight. I can find no correction in PDB or WinChloe. Observe that sBb6 serves no purpose. If we remove it, then wLb5 serves little purpose. Removing both units, and shifting wD to e1,e5,e6,g6 or h5 retains soundness, but gives Black a last move. All variations persist, including the minor dual after 1. ... Lxb7, where both mates are separately forced. I prefer wDe6, because the key defending Sc8 is otherwise too strong. Also note the try 1. Dg8? In summary therefore: correction krN5/pN6/b2KQ3/8/8/8/R7/8 #2. (2021-10-09)
A.Buchanan: WinChloe gives a different original source, Wiener Schach Zeitung, with the same year 1932, towards the end of Keeble's chess problem career. (2021-10-09)
Mario Richter: My guess is, that the publication in 'Wiener Schach-Zeitung' is only a reprint as part of what I call "a real solving competition" (since amongst the problems to be solved there were also [intentionally] some with severals cooks or with seemingly or real illegal positions):
"Aus dem diesjährigen internationalen Lösungswettkampf.
Diesem Turnier ... lagen zum Teil sehr knifflige Probleme zugrunde. Es sei für unsere Löser vorausgeschickt, daß die Aufgaben zum Teil mehrfach nebenlösig sind, mitunter eine partieunmögliche Stellung vortäuschen oder auch haben. Die Illegalität der Stellung ist zu beweisen." (2021-10-09)
A.Buchanan: Wow, thanks Mario! This is a great example then of how one can't understand a problem sometimes, without knowing the context in which it's composed. How should we classify this one here in PDB? (2021-10-09)
A.Buchanan: Since illegality is the intention, it's not cooked. And it's a joke. bBb6 is a weasel. So much is clear, but I am uncertain whether to use the descriptive keyword "illegal position" or "no legal last move for black" or something else. The latter is actually a retro-stalemate (defined as a one-sided illegal position). However, 'retro-stalemate' as a keyword it has the sense more of applying to retro compositions where a retro-stalemate is sought in the history of the game, not Article 15 cases where the diagram is already one-sidedly illegal. So I think we should keep the keyword 'no legal last move for black'. (2021-10-10)
