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.

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)

Henrik Juel: The late part of the solution is dualistic (2020-08-14)
Joost de Heer: The first dual is already at move 6 (Kb4 or Kc4), so it's not just the late part that's dualistic. (2023-01-30)

bitte prüfen. (2023-05-10)
SCHRECKE: Die Definition des Excelsior beinhaltet lediglich:

Henrik Juel: I agree with Michael
An Excelsior does not require immediate mate by the promoted pawn (2023-05-11)
Dieter Berlin: Hallo Michael und Henrik,
im 'alten' Sidler von 1968 habe ich auf Seite 27 die Excelsiorbeschreibung gefunden
und deshalb den Kommentar abgegeben. Sollte sich die Auslegung inzwischen geändert
haben, ist meine Frage, ob und wo man das evtl. nachlesen kann. Beste Grüße! (2023-06-30)

Henrik Juel: Congratulations, Miguel
This the first correct entry by you, I believe
It still needs author and source, though (and possibly a twin) (2023-07-24)
A.Buchanan: Hi Henrik, we are working to automate the process of uploading these problems. It will take a day or so, after that should be smooth. (2023-07-25)
Miguel Ambrona: Thanks Henrik!
This is a problem I composed a few years ago, before I know about the notion of twin. I may work on it at some point.
