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#
Verführung: 1. Ta5+? Kxb4 2. Sc6+ Kc4 3. Tc5#

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)
