Max J. Meyer in 'Brighton and Hove Society', 1904: "It will be seen that the ideas of these two problems [dieses und P1143870] are the same. The addition of the White B. enables Mr. Mackenzie to get a much better key for this position, a point in which Steinweg's problem does not excel; but, of course, the use of an extra piece renders the miniature less remarkable from the point of view of smallness in size."
Paulo Roque: .
Solution:
1) 1. La7 KxLa7 2. c8=T! Ka6 3. Ta8#

2) Proof da legality of the answer:
Retro: 0... Ka7-a8 -1. b7-b8=L etc (2009-09-06)
Sally: Der letzte weiße Zug von Weiß kann nur Ba7xb8L gewesen sein, demgemäß enthält die Aufgabe 2 Bauernumwandlungen
in verschiedenen Figuren: in der lösung in einem turm und retrospektiv in einen Läufer.

Henrik Juel: There is even a third promotion in the threat 2.c8=D+
C+ by Popeye 4.61 (2016-08-30)
A.Buchanan: Here the threat play (1) is sound & (2) can never occur as Black has no neutral move. But if threat play is *unsound* yet can never occur, can it be safely ignored or will some directmate purists regard that as a defect? (2022-04-02)
Henrik Juel: I think not, Andrew
When I test problems, I ignore plays that do not occur (2022-04-02)

A.Buchanan: Why would we talk of helpmate promotions (particularly black ones) as underpromotions. Is a knight ever an under-promotion? And we still with all this under-promotion effort don’t know what the pieces are: it might be rook or bishop. Just label them as promotion:lts and be done (2023-01-12)

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)

En bichromatique la légalité de la position ne pose pas de problème : pas de Fou en dehors de la case de départ ou de la ligne de promotion, ni de pion s doublés ou croisés. En monochromatique : Les B ont joué Tb3-d3+, mais il faut aussi justifier la position des Pions.Le Pf3 n'a pris ni la Dame, ni un Fc8 ni un Cavalier, ni Ta8 qui n'a pu venir sur la 3° rangée, il a donc pris un Pion.Compte tenu du Pc2, cela suppose 5 prises sur case blanches par PN : la D, le Ff1 et 2 pions seulement puisqu'il reste les Pf3 et d7. La Ta1 n'a pu être prise puisqu'elle se trouve en d4. La 5° prise s'explique par la capture d'un Pion sur case noire par prise en passant sur d3.

Mario Richter: Henri Nouguier's comment seems to indicate, that Black necessarily did capture ep on d3. But that is not correct, since the position can be reached without that capture too ... (2021-08-13)

Die Nachtwächterin sDh1 ist in einigen Nachdrucken weggelassen.
Historisch: Womöglich die erste Exzelsior Darstellung im direkten 5-Matt.?! \eb
Sally: Hier kämpft sich der w. Bauer d2, von der 2 Reihe mit Pauken und Trompeten bis zur achten Reihe, um sich dort in einen Springer umzuwandeln. Die s. Dame h1 nachtwächtert!
In manchen Aufgaben ist sie gar nicht abgebildet, soll wahrscheinlich die Lösung erschweren.
70 Schach ohne Patrner für Könner (2016-09-06)
Henrik Juel: Besides sDh1, also sPb3,f3,g3 may be omitted (2020-04-02)
SP: This is not the earliest excelsior in a #5; see 155 p. 321 in Chess Nuts,
originally published as 23 Porter’s Spirit of the Times 7/ii/1857.
Initially attributed to “Q. B. M.” of Newberry, but this was later (28/ii)
changed to O. B. M., when a later original (No. 26) was sent in by E. E. G.
of Newburyport (Mass.). (2023-02-16)

A.C.White: "We have become accustomed to 'tries' being defeated by the trick of a minor Black Pawn Promotion, but a quarter of a century ago the device was a new one and almost all solvers would have been caught by it. Loyd was so successful with it that he tried it once more at the St. Louis meeting of the United States Chess Association in December of the same year (No. 462). There was a time limit of an hour and a half, and all the fourteen competitors failed to discover the trap in that time."

A.Buchanan: PDB gives us very little flexibility for describing the quality of problems. I suppose we should record duals in the "Cook" field for now. Everyone would agree that the trial is a defect. But duals are not cooks, and even if we accept that "Cooked" is PDB-speak for "Unsound" for now, it would go against the view of many problemists to mark this celebrated problem as unsound. It would also violate Codex Section III https://www.wfcc.ch/1999-2012/codex/#c3. (2021-11-07)
