Rolf Wiehagen: Siehe P0500863, Gerhard Pfeiffer 1985, mit 10 schwarzen Bauern, und P1087039, Reinhardt Fiebig 2005, mit 9 schwarzen Bauern.
Spezielle ehrende Erwähnung von Preisrichter Boris Shorokhov, der in seinem Preisbericht schreibt:
"Für drei Umwandlungen schwarzer Bauern in Damen werden neun Züge benötigt. Bisher gelang dies nur mit zu vielen schwarzen Bauern, d.h. in illegaler Stellung. Der Autor dieser Aufgabe vermeidet solche Positionen, aber die erste Umwandlung in eine Dame ist retroanalytisch begründet, offensichtlich war 1. d1=D+ der letzte schwarze Zug. Natürlich ist das nicht dasselbe, aber nach meiner Meinung verdient die Findigkeit des Autors eine spezielle Auszeichnung." (2021-04-22)
James Malcom: This problem is mentioned on berlinthema.de on 159 of this document: http://www.berlinthema.de/AUSWAHL_PH.pdf (2022-01-31)
A.Buchanan: It would be cool if our keyword system distinguished cleanly between retro & forward promotions. However we have too much clutter in the current vocabulary to extend in this way right now, imho. (2022-01-31)

Lösungsbesprechung: “Der Autor erweitert eine lang bekannte Mattführung durch ein frühes, überraschendes L-Opfer. Hat seine Daseinsberechtigung, doch eigentlich müsste es heißen: ‚nach C. F. Jaenisch‘, P1171799 von 1837!” [BK] Die Ursprungsidee ist sogar noch älter: “Die zweitlängste Darstellung des 1-Springer-Idealmatts in der Ecke. Es gibt viele Bearbeitungen dieser Mattführung, zuerst gezeigt als #5 im Manuskript 'Bonus Socius' vom Ende des 13. Jahrhunderts (P1129965 oder P1156023). Den Rekord hält die P1124546 von Günther Jahn 1983 mit 16 Zügen! Ansonsten sind mir nur Fassungen bis zu 10 Zügen bekannt.” [Klaus Funk] Eine “schöne Miniatur” [BL], “bei der sogar der wL noch geopfert werden kann!” [JB]
Vergleiche aber auch P1313738.

Asymmetry, but not very striking because of the proximity to the a-line
Still a very nice problem, which is solvable by hand (2021-02-07)
A.Buchanan: Nice to have an empty board for the nightriders to canter around in unblocked. That they are line pieces makes the uniqueness of the solution even more impressive. Someone must have already done tablebase for this endgame (2021-02-08)

A.Buchanan: Please forgive me but I think “under-promotion” is only meaningful for directmates and studies. That’s why I had put in promotion as a keyword, not under-promotion. In helpmates, promotions need to be distinguished of course, and we can put in the officer type in the parameter slot. Under-promotion would still need such a parameter because it’s inexact itself: the worst of all worlds. Even for directmates and studies of course some people consider knight promotion not to be an under-promotion at all, but I wouldn’t go that far myself. There are far too many keywords covering promotion, and at some time we should clean them up, but in the mean time I am open to considering another opinion if it is explained to me. Thank you.
