Schwarz hat keinen letzten Zug, daher beginnt er (und setzt in 3 Zügen matt):
1. ... T3d2+ 2. Lexd2 Txd2+ 3. Lxd2 Ta1#,Db3#; 3. Lb2 Txb2#,Db3#; 3. Kb1 Txc1#

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)

The shortest proof game is rather long! (2003-12-19)
Moldenhauer: Histogramm Stelvio 1.2 128/0k bei BP 37.0.
Kein Histogramm bei BP 36.0, BP 36.5. Computerprüfung wird sehr lange dauern
da eine 5+1 auch nach 5 Stunden noch nicht fertig ist! Nur 49 Strategien sind
unter 5+1. Vielleicht kommt aber das "cooked" früher dazwischen. (2023-05-10)

Henrik Juel: In the official solution 16.Sd8-e6 is illegal, because wKc6 is checked (this seems fixable)
My 2004 solution also works, so the problem is almost cooked (2023-07-23)

#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)
