Schwarz hat keinen letzten Zug, daher beginnt er (und setzt in 3 Zügen matt):

Die Umwandlung aller 16 Bauern in schwarzfeldrige Läufer bzw. in Türme erforderte alle 8 Schlagfälle, und zwar so, daß alle Umwandlungsfiguren auf schwarzen Feldern entstanden. Deshalb kann zuletzt auch keine schwarze UW erfolgt sein.
Joaquim Crusats: Can anyone explain the intention? (2013-01-06)
Henrik Juel: The eight white pawns captured the four missing black officers and promoted on b8, d8, f8, and h8; the eight black pawns captured the four missing white officers and promoted on a1, c1, e1, and g1.
If White had the move, 1.Ta5+? Kxb4 2.Sc6+ Kc4 3.Tc5 would mate in three.
But Black has no last move, so he has the move and mates in three by 1... T3d2+ 2.Lexd2 Txd2+ 3.Kb1 Txc1# (2013-01-06)
A.Buchanan: This is one of a number of problems which had been given both "No legal last move for..." & "Whose move?" keywords. These should correspond respectively to two situations: (1) Codex Article 15 where we add or remove a single move from the beginning of the solutions, but the mating party remains the same. (2) A kind of one-sided duplex, where who moved last implies who delivers the mate (or other final move).
So at most one of the two keyword forms can ever logically apply to a problem. Therefore I have removed the incorrect "No legal last move for Black" keyword.
We might replace "Whose move?" by "Halfduplex", which is related to the Popeye option. What do you think? (2023-11-28)
A.Buchanan: This is a nice problem. There are some final move duals for the actual solution, but all missing units are needed to justify promotions (2023-11-28)
Henrik Juel: Halfduplex is a bit too technical for my taste, although it describes the goings on well (2023-11-28)
A.Buchanan: Thanks Henrik - I'll leave the term "Whose move?" as it is then. (2023-11-28)

bPa & bPh promoted with wPaxb7 & bPhxg6 to clear the way. There is an inner cage containing all the White officers, and White has only 6 current retractions. So Black must unpromote something. Both White captures were on light squares, so Lf4 is original.
1) Lf3 to h1. For speed, White must uncapture Ceriani-Frolkin D on g6, which arrives on a1 in 2 unmoves. When White uncaptures L on b7, it's Phoenix of the original.
2) Tf8 to a1. (It's too slow to unpromote on h1). When White must uncapture on b7, g2 is already blocked, so White must uncapture S, and unpromote that or one of the other Black S. However, the inner cage has been breached, so the clock has stopped now. Eventually, White will uncapture Phoenix T on g6.
The tempo is exact in both cases, so White, not Black must have the move.
A.Buchanan: Very nice - exactly matching lengths across the two lines and complementary non-trivial forward play (2021-10-21)
Henrik Juel: HC+ Popeye 4.61 (2021-10-22)

All missing pieces accounted for. Easy to see White has no last move.
R: 1. S6-d8? 0-0 means wK stuck behind Black lines.
1. fxe6ep is not permitted, and leads to no mate anyway.
Corrected suspected typo, by putting wBe6 on f5.
Mario Richter: As given, the position is illegal: 3 white pawn captures, but only 2 missing black men. (2010-01-23)
A.Buchanan: I think this is a typo: wBe6 should be on f5. Then the two candidate solutions are C+ 1. Txd8+ Kxd8 2. Kf8 Th8# & 1. Kxb7 Txd8 2. Ka8 Le4# WinChloe has the same diagram. Note the uncastling try. En passant for once is not part of the problem. If others here concur, I will correct this diagram in place. (2021-10-20)

7 Black pawn captures: QRRBSSPP
2 White pawn captures: QSP
If White just moved, then d2xe3, and wBc1 retro blocked. This means all captures accounted for, but how did h pawns pass?
So, WTM.
There are numerous BWBW and BWB mates, but there is only one WBW mate.
A.Buchanan: Odd. As h#2 there are many solutions, not just the nice slow-rolling wPb one. And these are all eliminated for both retropat reasons and because they are longer than the actual one. Why is the stipulation not just h#2? (2021-10-20)

play all play one stop play next play all
Henrik Juel: White has the move
-1... f4xLg3 -2.Lh4 f5 -3.Lf6 h3 -4.Lb2 h4 -5.Lc1 h5 -6.b2xLa3 Lc5 -7.e3 Ld4 -8.c5 Lf6 -9.c4 Le7 -10.c3 Lf8 -11.c2 e7xTd6 -12.Td4 Kd8 -13.d6xTc7, retract Td4 to h1, Ka8 via g6 to e1, Pd6 to h2, g3-g2, g2xLf3 etc. (2013-08-28)
James Malcom: Is the given retraction unique? (2020-11-08)
Henrik Juel: Unique up to 11.c2-c3, I think (2020-11-08)
Henrik Juel: One of my favorite retros with just kings and pawns
even though the retroplay is not completely unique (so my previous comment is imprecise)
R: 2... h3-h2 3.Lf6-h4 h4-h3 or 3... f5-f4 also work
but not R: 1.e3-e4? or 1.c5-c6?, and White runs out of pawn retractions
nor 2. e3-e4? or 2. c5-c6? f5-f4 3. Le5-g3, and same difficulty (2020-11-09)
Henrik Juel: In the forward play we have several temporal implications, e.g.,
e2-e3 before b7xLa6 before g2xLf3 before g3-g2 before h2xg3
d6xc7 before e7xd6 before b2xLa3 before f4xLg3
Thierry was inspired by P0008574 (2020-11-09)
James Malcom: I see the similarities as well. If Thierry's last 21 moves, stopping at 11. c2-c3 of course, are indeed unique, it seems to be the record for a kindergarten position? (2020-11-09)
A.Buchanan: I think the last 2 single moves are determined. Prior to that it could be f5-f4 or h3-h2, no? (2020-11-10)
Henrik Juel: You are right, Andrew
So, no record, James (2020-11-10)
James Malcom: Ah well then-the linked problem with 16 moves by Gerd oughtta be it then, from what I've searched so far. (2020-11-10)
A.Buchanan: Isn’t the retro record one of the Breyer versions by Thierry Le Gleuher? (2020-11-10)
James Malcom: As far as I know, the TOTAL retro record is, all from P1339006, by Theierry indeed: Type A, 100 moves, Type B, 101 with bP6-h6 & White to move, and, finally Type C, 102 with bP6-h6 and wSc7-a8. (2020-11-10)
James Malcom: For Type B, I meant "bPh5-h6." (2020-11-10)

Schwarz kann nicht zuletzt gezogen haben
1. ... a1=D,L+ 2. Td4 Sc6#
play all play one stop play next play all
Originallösung (1880, S. 213):
Dalla posizione apparisce che il Nero deve avere lamossa, perchè nessuno de'suoi pezzi può avere avuto l'ultimo tratto.
Cioè:
a) Il R nero non può coll'ultimo tratto esser venuto da 5 A pr; allora l'ultimo tratto del Bianco dev'essere stato C 6 D, ciò che fa supporre , o che il tratto penultimo del Nero sia stato A 2 A sc. (ma di dove è venuto in tal caso l' A?), o vhe il C ha preso un pezzo nero a 6 D; ma i Pedoni 4 R, 4 A, 4 C hanno preso tutti i pezzi neri che si trovano nel diagramma.
b) Il P 7 TD che è venuto da 6 C es ha preso tutti e due i pezzi bianchi mancanti non può essersi mosso nell'ultimo tratto.
c) Il P 3 R che è venuto das 2 R (perchè non pu`aver preso nessun pezzo) non ha fatto l' ultimo tratto; il che si può vedere dalla posiziopne di A 2 A (che non può essere il P A R trasfigurato).
d) La posizione del R bianco mostra che il C 5 T non s' è mosso ultamente.
Dunque da tuttociò apparisce che il B ha fatto l'ultimo tratto, e ora il Nero giuoca: 1. P 8 T fa D sc. 2. T 4 D C 6 A sc.m."
[Sinngemäß: Aus der Stellung geht hervor, dass Schwarz am Zug sein muss, da keine seiner Figuren den letzten Zug ausgeführt haben kann.
Nämlich:
a) Der schwarze K kann mit dem letzten Zug nicht von b5 gekommen sein, denn dann müßte der letzte weiße Zug Sd6 gewesen sein, was bedeutet, daß der vorletzte schwarze Zug Lc7+ gewesen sein muss (aber woher kam in diesem Fall der sL?); oder wenn der wS auf d6 einen schwarzen Stein schlug; aber die Bauern e4,f4 und g4 haben alle im Diagramm fehlenden schwarzen Figuren geschlagen.
b) Der sBa2, der von b3 und zuvor von der c-Linie kam und dabei die beiden fehlenden weißen Steine ??nahm, kann im letzten Leg nicht gezogen haben.
c) sBe6 kam von e7 (weil er keine Figur hätte nehmen können), kann aber zuletz nicht gezogen haben, was aus der Position des sLc7 ersichtlich ist (der kein aus dem sBf7 entstandener UW-L sein kann [letzterer konnte nicht schlagen und deshalb kein schwarzes UW-Feld erreichen]).
d) Die Position des weißen K zeigt, dass sich der sSa5 nicht zuletzt bewegt hat.
Aus all dem folgt also, dass W zuletzt zog, und jetzt spielt Schwarz: 1. ... a1=D+ 2. Td4 Sc6#

(Daß Autor, Löser und PR übersehen haben, daß der fehlende sLc8 nicht als Schlagobjekt für die wBB zur Verfügung stand, ist umso erstaunlicher, als ja andererseits eine analoge Analyse R: sBe7-e6 als letzetn Zug ausschloß.)
Cook: Illegal position in retro = unsound = "cooked, in crude PDB terminology"
Originalforderung: "Chi comincia a giuocare dà scaccomatto in 2 mosse. Dalla posizione dei pezzi come pùo scuoprirsi chi debba avore necessariamente il tratto?"

#1 (Wer?)
1. Dc4#
play all play one stop play next play all
Mit Weiß von unten nach oben spielend wäre die Stellung illegal, also spielt Weiß von oben nach unten (Drehung um 180°) und kann mit 1. Dc4 (oder präziser 1. Df5 beim richtig orientierten Brett) mattsetzen.
eingebettet in eine Geschichte "Un peu de fantaisie - qui fait mat en un coup"
Henrik Juel: The reason for illegality is too many white pawn captures
axb, bxcxd, hxg need four missing black men, which is indeed the case, but [Lc8] was captured at home by an officer (2016-07-10)
A.Buchanan: 1.Sg3#? is the thematic try (2023-04-03)

play all play one stop play next play all
Da will Sie der Autor - so scheint es - in der Silvesteraufgabe auf die Schippe nehmen. Denn außer der ungewöhnlichen Forderung fragt er auch noch 'wie viele Möglichkeiten?' - Und das darf ja wohl nicht sein.
Cook: R: e.g. 1. Ke7-f8 Tf6-e6+
Stefan Kalhorn: Was ist mit 0.Tf6-e6+ Ke7-f8 und Weiß wäre am Zug? (2021-01-03)
Henrik Juel: Yes, White may have the move, so Keyword is wrong
Correction: add wPd6 (2021-01-04)
A.Buchanan: Sf5 Bg5 (2021-01-04)
Henrik Juel: That also seems to work, but then the try 1.Le7#? is lost (2021-01-04)
James Malcom: Seems to me that the simple +wPd6 fixes all and keeps the content. (2021-01-04)
A.Buchanan: How do we know the intention is not to have 5 solutions? This is meant to be a Christmas puzzle after all (2021-10-11)

Schwarz zog zuletzt nicht und ist am Zug, aber laut Forderung soll Weiß am Zug sein. Das funktioniert nur, wenn Weiß seinen begonnenen Zug vollendet:
