Felber, Volker: a,c,d unlösbar. Retro? Kein letzter Zug von Schwarz (2020-12-22)
Marcin Banaszek: Die Lösungen sind O.K. Der schwarze König kam von f5/f6, nachdem weißer Bauer f3/f4 auf g4/g5 geschlagen hat. (2021-01-15)
Mario Richter: Für a) stimmt Marcins Erklärung, aber bei c) und d) hat Volker recht: dort hat Schwarz jeweils keinen legalen letzten Zug! Ich halte die Aufgabe deshalb für "cooked"! (2021-01-16)

Henrik Juel: The requirement for this tourney was something like: H#2 with retro content, so successful entries are retro problems, almost by definition
The judges must have considered that the counting here suffices as retro content
One of the other awarded problems has even less retro content: Last move could not be a pawn capture, because the other side has 16 men (2021-01-02)
Mario Richter: I think Andrew's analysis is not correct, especially his claim "There is no reason that any of these [i.e. the black promoted pieces] need still be on the board"
In fact, Black has promoted FOUR (not 3) of his pawns, twice on c1, twice on d1. The lower right corner can only be opended by retracting d2xe3, before that is possible, all four black promotions must be retracted - the only pieces available for that are Da7, Tb7, Lb8 and Sg8.
In the forward play, exactly these four black officers are captured - does that make them some kind of "Forward-Ceriani-Frolkins"?! (2021-01-02)
A.Buchanan: @Henrik,Mario: I've hidden my prior posts, although I feel I'm clearer now in my mind about what makes a retro-problem. However in the analysis here, I missed the key retraction point: thanks for picking it up. So retracting, Bl unpromotes Phoenix AUW, and uncaptures include wT' & wL' (where ' and " can denote queenside/kingside - I've been looking for a handy notation for this for a long time). With these pieces at home, Wh can unlock the cage as Mario says with dxe3. So the board contains 4 promoted units, which in current PDB terminology, we could only call "obtrusive". We must fix this naming hole. In their encyclopedia, V&V identify 4 kinds of promoted force [with some clarifications by me, including adding a 5th category]. [Each promoted unit should fit into exactly *one* of the categories, although it may not be possible to determine which exact unit is which.]
(1) In the initial problem position there is a piece that can [obviously] only have come through promotion, so-called obtrusive force, e.g. a white dark-squared Bishop, with Pawns b2 and d2 still on their original squares;
(2) [In the initial problem position] promoted force that adds the number of pieces from the game-array, for instance three Rooks or two light-squared Bishops of same color (non-standard material);
([3]) [In the initial problem position] pieces the origin of which has been promotion, which can be deduced only by retrograde analysis, i.e. there is nothing in the position that suggests it is promoted force. [This category needs a proper name, otherwise it will be forever conflated with obtrusive promotions. These are phoenix/prenix, but in many cases we won't be able to distinguish which, and wouldn't care anyway. Are the terms phoenix/prenix are only used for units still on the board?]
[(4) promoted units which have been captured before the initial problem position (Ceriani-Frolkin)]
([5]) pieces that promote during the course of solution.
The pieces of group (3),(4)[&(5)] are allowed, the pieces of group (1) are tolerated, although avoided, whereas the compositions of group (2) are rejected unless there is, say, a theme tournament for compositions with non-standard material.

comment
The judges must have considered that the counting here suffices as retro content
One of the other awarded problems has even less retro content: Last move could not be a pawn capture, because the other side has 16 men (2021-01-02)
Mario Richter: I think Andrew's analysis is not correct, especially his claim "There is no reason that any of these [i.e. the black promoted pieces] need still be on the board"
In fact, Black has promoted FOUR (not 3) of his pawns, twice on c1, twice on d1. The lower right corner can only be opended by retracting d2xe3, before that is possible, all four black promotions must be retracted - the only pieces available for that are Da7, Tb7, Lb8 and Sg8.
In the forward play, exactly these four black officers are captured - does that make them some kind of "Forward-Ceriani-Frolkins"?! (2021-01-02)
A.Buchanan: @Henrik,Mario: I've hidden my prior posts, although I feel I'm clearer now in my mind about what makes a retro-problem. However in the analysis here, I missed the key retraction point: thanks for picking it up. So retracting, Bl unpromotes Phoenix AUW, and uncaptures include wT' & wL' (where ' and " can denote queenside/kingside - I've been looking for a handy notation for this for a long time). With these pieces at home, Wh can unlock the cage as Mario says with dxe3. So the board contains 4 promoted units, which in current PDB terminology, we could only call "obtrusive". We must fix this naming hole. In their encyclopedia, V&V identify 4 kinds of promoted force [with some clarifications by me, including adding a 5th category]. [Each promoted unit should fit into exactly *one* of the categories, although it may not be possible to determine which exact unit is which.]
(1) In the initial problem position there is a piece that can [obviously] only have come through promotion, so-called obtrusive force, e.g. a white dark-squared Bishop, with Pawns b2 and d2 still on their original squares;
(2) [In the initial problem position] promoted force that adds the number of pieces from the game-array, for instance three Rooks or two light-squared Bishops of same color (non-standard material);
([3]) [In the initial problem position] pieces the origin of which has been promotion, which can be deduced only by retrograde analysis, i.e. there is nothing in the position that suggests it is promoted force. [This category needs a proper name, otherwise it will be forever conflated with obtrusive promotions. These are phoenix/prenix, but in many cases we won't be able to distinguish which, and wouldn't care anyway. Are the terms phoenix/prenix are only used for units still on the board?]
[(4) promoted units which have been captured before the initial problem position (Ceriani-Frolkin)]
([5]) pieces that promote during the course of solution.
The pieces of group (3),(4)[&(5)] are allowed, the pieces of group (1) are tolerated, although avoided, whereas the compositions of group (2) are rejected unless there is, say, a theme tournament for compositions with non-standard material.
For retro-problems somewhat different conventions apply, although these still meet the standards set for orthodox problems.[I don't understand this last sentence at all. Mario can you explain please.] (2021-01-03)

PR Robert Lincoln: " Ojanen theme layout much more economical than the sample in the appendix. [P1132287] It is not a closed system since random moves permit all threats to ensue. Yet, intense efforts to utilize minimal means should be recognized."
A.Buchanan: It's possible to "close the system" with wR instead of bP e.g. 3k3n/3p1B2/5K2/2R5/8/4B3/8/8. I guess that in this kind of formal theme, 1. ... a6,a5 counts as a defect, and that requires an 8th unit to fix: 3k3n/N2p1B2/5K2/3N4/8/8/8/2B5 (2021-06-12)

The march of the immortals
A day – 24 hours. After two high ranking white officers fell in battle, seemingly for no good reason, the meaning of these selfless sacrifices quickly became clear. Two white pawns were assigned the duty of keeping the black king tight in his safehouse. They did this with honor and for glory. Then the white king, the leader of the army, took it upon himself in these still early morning hours to take on a long march of 17 hours.
Now mid-evening has fallen and he arrives, exhausted but glad and hopeful now that he has the enemy in sight. He breaks open the safehouse, personally taking out a guard, but also requiring the further sacrifice of one of his own beloved soldiers. Finally the battle of the kings begins, but being a gentleman ruler and soldier in all things, he calls for his queen to deliver the final blow, a perfect one, to give her the satisfaction of the kill, as the bell tolls midnight and the beginning of a new and glorious day.

Mirko Degenkolbe: Gut erkannt Frank.
Leider wurde in der LöBe in PU nicht darauf eingegangen.
Zwei der drei Kurzvarianten sind eindeutig, eine hat einen einzigen Dual.
Eine hat sechs Züge, die anderen beiden deren sieben.
Etliche Versuche, alle vier auf eine Länge zu bringen, scheiterten kläglich.
Iwan hat es auch nicht hinbekommen.
Siehst du eine Möglichkeit?
Ansonsten sollte vielleicht ein anderes Schema probiert werden.
Ideen, Pläne, Vorschläge? (2022-02-22)

Henrik Juel: At first I was surprised to see the move 1.c5
But it follows from Einstein: a pawn on its first row can move 1, 2, or 3 steps ahead
(Since Black is moving, nPc8 acts as a black pawn)
It is amazing what Michael can do with four men and four conditions (2022-04-11)
Henrik Juel: My only beef is that in the mate position (nKh8, nLg6, nPg7h7) nLg6 serves no purpose (2022-04-11)
