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)

'The Good Companion Two-Mover' gibt als Quelle an: "3002 G.C., July 9th, 1921", tatsächlich steht das Problem aber auf der Titelseite des G.C. Folder vom August 1921.
Evtl. wurde das Problem auf dem Good Companion Day, Atlantic City, N.J., July 9, 1921, präsentiert, oder es gab anläßlich dieses Ereignisses eine Sonderausgabe?!

Die Lösung wurde in SE nicht veröffentlicht, die Schachecke ab 01/1992 eingestellt.

MD: Grimshaw als Thema-A-Paraden in der Verführung, vornehmer Nowotny mit Drohrückkehr in der Lösung; Fluchtfeldgabe und Unterverwandlungen als Garnierung.
(MD114)
HBae: vgl. P1300218 mit gleicher Matrix (2021-08-30)
Mirko Degenkolbe: Gleiche Matrix ja, aber durch die thematische Verführung eine deutliche Aufwertung des Inhaltes. Auch kannten wir die Vorarbeit aus Hamburg nicht, als unsere Aufgabe entstand. (2022-03-19)

Henrik Juel: The late part of the solution is dualistic (2020-08-14)

Solution text from the 2/1899 issue: "A clever rendering of this "triple idea." It will be seen that Black cannot play simply 2.R-Q sq on account of 3. Q x Q ch."
zum Autor heißt es im 'ACM': Courtenay Lemon, New York
James Malcom: I found this most excellent early Valladao while ago, but only today did I finally find it again. This is the second one that I've found, i.e. P1380523

Is this the second oldest known Valladao after the 1867 P1360420 found by Keym?

The mainline should be C+, with the "legitimate" ep key, but with many dualed sidelines. (2020-10-14)
Henrik Juel: Something seems missing, James
There is no mate 3... Kc8,Kxc6 (2020-10-14)

bitte prüfen. (2023-05-10)
SCHRECKE: Die Definition des Excelsior beinhaltet lediglich:
Die Darstellung des Marsches eines Bauern von seinem Ausgangs- zu einem Umwandlungsfeld ... (2023-05-11)
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.
