Henrik Juel: This problem was incorrectly printed as 6842 TD 84 10/1996, so it was discarded and did not participate in the 1996 informal tourney
It was correctly printed in the next issue as 6927 TD 85 1/1997 and won the award in the 1997 informal tourney (2021-05-21)

A.Buchanan: Henrik: I love these many-handed accomplishments: please can you tell us more about the creative process whereby 7 composers collaborated on the arrangement of just 5 pieces? (2021-03-30)
Henrik Juel: I only saw your comment today, Andrew
Most of these small problems with many authors came about as a result of a sort of theme tourney, and that is also the case here
The TD editor, Holger Helledie, posed several construction exercises with very short deadlines
Here he asked for a helpmate problem with two black S promotions and minimal force
The theoretical minimal force would be KP-KPP, but nobody submitted this
The second best is KS-KPP, and six participants indepently found this problem
Holger had found it himself, so he is included as author
The winner of this exercise was the strong finnish composer, Unto Heinonen, with KL-KPP (2021-04-25)
Henrik Juel: Unto's problem was P0504865 (2021-04-25)
A.Buchanan: Thank you for the details. So the mental picture I had was incorrect: a troupe of composers muttering around a single chessboard, irascibly nudging a smaller number of pieces from square to square. (2021-04-25)

Henrik Juel: Back in the old days two light-squared white bishops were unthinkable
And some people considered the knight more economical than the bishop
The problem is from a construction contest: h# with white and black promotion (2021-05-24)
A.Buchanan: In some ways, Henrik, composition is about trying to find the best natural form that a problem is trying to take. I wasn't trying to think the unthinkable, but when I finally thought it as the only way to salvage and indeed amplify your idea here, I started looking forward to reading your response :) If you don't want it, that's absolutely fine - I will claim it as an "after HJ", and try to find some "Salon Des Refuses" in which to exhibit it (2021-05-24)

Adrian Storisteanu: Old habit of putting the wK teasingly close to the main stage, while still not causing unnecessary cooks... (2021-05-25)
Henrik Juel: Your suggestion is fine, Andrew
Composing exercise 50 was announced in Thema Danicum no. 72, where the editor Holger Helledie asked for help mate problems with 1 white and 1 black promotion, as long as possible
Theodor Steudel pointed out that problems as short as possible were also relevant, and the submitted problems along with many old ones were shown in TD no. 73, where HH expanded the criteria to
1. As few men as possible (4 was achieved in 1927: Kh8 Pf7 - Ka1 Pb3, h#2)
2. Shortest or longest possible (from h#1.5 to h#10, the latter from 1956: Kc1 Pc2 - Kh7 Pc3e4)
3. Economy of the men
4. Publication date
Four more problems appeared in TD no. 74, where HH announced his resignation as editor
I considered my contributions as one of the many low points in my composing career, such as it is, and initially excluded them from the compilation, I am working on; but now I have changed my mind... (2021-05-25)

There is some choice in the retro path, but in the shortest resolution, the sK round trip is uniquely defined: e8-c8(castling)-b8-c8(switchback)-d7-d8-e8. Note that wTa, still stuck in its cage, was captured on c2.
Mu-Tsun Tsai: Can't believe that this one didn't get the 1st prize. The design is really brilliant! (2011-04-17)
Henrik Juel: Thanks for your nice words, Mu-Tsun. In 1997 there were few retro problems in Thema Danicum, and they were judged together with fairy problems, so the competition was stiff. (2011-04-17)
Henrik Juel: Thanks for posting the solution, Andrew
Two minor points:
The uncheck plusses should be R: 1. ... g7xSf6 2. Sg4-f6+ Kd8-e8 3. Se5-g4 Kd7-d8 4. Sc6-e5+ Kc8-d7 5. Sd8-c6 Kb8-c8 6. d7-d8=S Kc8-b8 7. c6xTd7+
sK could wander around on the queen side while wS pendulates on, say, g4 and h2; but in the shortest resolution the sK round trip is unique (2021-01-17)
A.Buchanan: welcome Henrik - also added the famous sLf8 to the animation (2021-01-18)
Henrik Juel: Six of the pawn captures happen to be uniquely determined, namely
b5xLc6xTd7, c3xDd4
d3xTc2, d7xLe6, g7xSf6 (2021-01-18)
A.Buchanan: An earlier sequence where timing was important: dxTc2+ Kc1 Td3/Sd3+ exd3 (2021-01-18)

Henrik Juel: White captured Sb5xQc7 and Be8xRf7. Black captured a7xPb6, c6xRd5, d7xRc6, e7xBd6, h7xPg6, Qc7xSc8, and Rf8xSf7 five times. (2003-10-14)
James Malcom: What is the full solution? (2023-05-30)
Henrik Juel: The retroplay is something like
R: 1. ... Sh7-f8+ 2. Le8xTf7 Tf8xSf7 3. Se5-f7 Tf7-f8+ 4. Sc4-e5 Tf8xSf7 5. Sh6-f7 Tf7-f8+ 6. Sa3-c4 Tf8xSf7 7. Sg5-f7 Tf7-f8+ 8. Sb5-a3 Tf8xSf7 9. Se5-f7 Tf7-f8+ 10. Sc7-b5 Tf8xSf7 11.

Earlier in the game Black captured a7xPb6, c6xTd5, d7xTc6, e7xLd6, h7xPg6, and White promoted on a8, c8, d8, h8.
The full retroplay back to the initial array can be constructed from this information; it has been done in a solution comment to Goldsteen's wonderful P0002345, which has no Pf2 in the diagram position (2023-05-30)

Erster Züge der schwarzen Bauern: a7xSb6, c7-c6, d7xSe6, f7-f6, h7xTg6
Henrik Juel: The first moves by black pawns who moved were: a7xSb7,
c7-c6, d7xSe6, f7-f6, h7xTg6. Retroplay e.g. -1.Ka4! b6xLc5 -2.La3 c5xTd4 -3.Lc1 c6 -4.b2xDTSc3; bring wK to g1 and wT to f1, and unpromote the uncaptured black officer on e1, e.g. -11.Kh1 Y=e2 -12.Kg1 e3 -13.0-0 f4xDe3 -14.De2 f5
-15.Dd1 g6xLf5 -16.Ld3 h7xTg6 -17.Lf1 c7 -18.e2xLf3 etc. (2006-07-13)
Henrik Juel: A few additional remarks may be necessary
White captured [Lf8] on f8, a2xb3x...xf7, b2xc3, and e2xf3, so all missing black men except for [Lf8] were captured by white pawns
Black captured a7xb6xc5, cxd, d7xe6, and made three more captures
d7xe6 happened after e6xf7, before [Lc8] could exit, implying:
1. [Pa2] captured DTTSS
2. [Lc8] was captured on f3
3. [Ph7] captured hxgxfxe, promoted on e1, and the promotee Y was captured on c3
Early in the retroplay Black must uncapture [Lc1] quickly, so White can retract b2xYc3 before Black runs out of pawn retractions
Later, White must retract [Dd1,Ke1,Lf1,Th1] quickly, so he can retract e2xLf3 before Black runs out of pawn retractions (2017-09-11)
Henrik Juel: This problem was awarded a Commendation (Lob) by judge Klaus Wenda in the informal fairy tourney (including retros) for 2005 (2021-06-18)

Die sBB schlugen die zwei fehlenden weißen Steine. wBb2 und wBd2 schlugen je einmal, der wBf2 schlug einmal zur Umwandlung auf e8 oder g8. Der Käfig kann nur aufgelöst werden, indem der sK nach d5 zieht. Dazu muß vorher das Schach durch wTb5 und wLb7 abgedeckt werden.

Thomas Volet: TV: solution given is slightly incorrect. Black's first retraction cannot be Se6-d4. It should be Sf5-d4, and the next two Black retromoves would then be Sd6-f5 and Sb7-d6. GW is so reliable I never check the solutions -- just happened to look at this one in connection with some correspondence. (2010-02-07)
Gerd Wilts: Thank you, Tom, I have now corrected the solution. (2010-02-07)
Mario Richter: Instead of ... 8.Lg8-e6 Dd4-d5 9. f7xLg8=L De3-d4 a.s.o. the unpromotion can also be done on e8: 8.Lf7-e6 Dd4-d5 9.Le8-f7+ De3-d4 10.f7xLe8=L a.s.o. Does that make the problem dualistic? (2010-02-08)
Thomas Volet: White also might have begun the game with either 1.Sg1-f3 or 1.Sg1-h3. The point was to show reciprocal retroscreens (here by the WBb7 and BQb4, each of which screens for and is screened by the other) involving both Kings. Beyond that .... (2010-02-12)
Henrik Juel: This problem was awarded 1st HM by judge Klaus Wenda in the informal fairy tourney (including retros) for 2005

Nach meinem Geschmack die anspruchsvollste der klassischen Retroaufgaben. Die 14-zügige Auflösung der Stellung mit wechselseitigem Schachschutz durch retroentfesselte Figuren, garniert mit der Entwandlung eines wL auf g8, wobei der entwandelte Bauer af sein Grundfeld f2 zurück zieht (Retro-Exzelsior), präsentiert sich als spannender und geistreicher Ablauf.
I expect that Mario's observation (that the unpromotion could also happen on e8) would not have changed the award; if the wording had been 'auf e8 oder g8', we would know for sure (2021-06-18)

Steen Christensen: The author is Erik Hansen. The problem was published as part of the “New Year Competition for Solvers” 2002/03. Henrik Juel commented: A great find with only one repetition (1. – Ka2). White having no last move is only a minor flaw. (2023-09-01)

Dr. Andreas Reinhard: I think after 182. Df1+ Ke4?? 183. d3 is #5 (2022-07-15)
Olaf Jenkner: Die Lösung war falsch angegeben, im Morsebuch steht sie korrekt.

182. Df1+ Ke4? 183.d3+ Kd5 184.Dxf5+ Kc6 185.De6+ Kb7 186.Db6+ Ka8/Kc8 187.Da6#/Dc7+
184. ... Se5 185.Dxe5+ Kc6 186.Dc7 Kb5/Kd5 187.Db6#/Dd6#

Richtig ist:

182.Df1+ Kg4! 183.De2+ Tf3 184.De6+ Tf5 185.Kd1 a3 186.Kc1 Kf3 ...

Der Dual ist zwar ärgerlich, er ändert aber nichts an der Korrektheit, denn die Variante 195.Df1+ Kg4 ist dualfrei. (2022-07-16)

play all play one stop play next play all

Duplicate Diagram: P1017583

Henrik Juel: Solution
All 8+8 pawns are on the board, and it is easy to count the east-bound pawn captures needed to give the diagram configuration
The a-file is pawnless, axb happened twice, bxc happened 2+2-1 = 3 times, cxd happened 3+2-0 = 5 times, and dxe happened 5+2-3 = 4 times, for a total of 14 needed captures; this number equals the number of missing officers, 7+7, so all captures were pawn captures, namely the ones just enumerated
This means that the pawns on the f,g,h-files never captured, so Pf5,g2,h3 are white and Pf7,g7,h5 are black
A sKf3 would stand in impossible check from wPg2, so Kf3 is white, and Ka3 and Pb2 are black
A sPe4 would give impossible check to wKf3, so Pe4 is white
[Lf1,Lf8] were not captured at home, so Pe2 is black and Pe7 is white
Now we have two white pawns on the e-file, so the white capture dxe happened at least once; this leaves at most six captures for the remaining three white pawns, and to reach the diagram configuration we need all these six captures, namely axbxcd, bxcxd, and cxd
This means that Pd3,d5,d7 are white and Pe3,e5,e6 are black, concluding the coloring
It is easy to verify that this coloring is a legal position; the only pitfalls in constructing a proof game are on the e-file, where Pe4 must be [wPe2] and Pe5 or Pe6 must be [sPe7] to ensure that the black e-pawn stands above the white one (2020-12-31)
Henrik Juel: The colored position is
White Kf3, Pd3,d5,d7,e4,e7,f5,g2,h3
Black Ka3, Pb2,e2,e3,e5,e6,f7,g7,h5 (2020-12-31)
