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)

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.

Dem Matt auf b2 (Lb2# oder b2#) steht der „falsche Block“ auf a2 (wTa2) im Wege. Dieser muss also von dort verschwinden, was nur unter ständiger Beschäftigung des schwarzen Königs möglich ist. Nachdem der weiße Störenfried weit genug weg vom Geschehen ist, überlegt es sich der weiße Läufer anders und blockt final auf dem Feld b1, weil der schwarze König nach a3 gelenkt wurde.
Wenn Schwarz „falsch“ fortsetzt (1. … b3?), kommt es schon zu einem S# in sechs Zügen. Leider gibt es dann nur eine saubere Kurzvariante, wobei dieses Mal der schwarze Läufer ebenfalls auf b2 mattsetzt.

Inhalt:
Die Verführung scheitert daran, dass kurz vor Toresschluss die sDg3 im Wege steht.
Deshalb muss diese Dame vorausschauend „aus dem Spiel“ genommen werden. Paradoxerweise geschieht dies, indem sie in der Lösung den aktiven Part übernimmt, und die in der Verführung aktive sDe7 übernimmt dieses mal den „passiven“ Part.
Außerdem sehen wir in der Lösung einen Platzwechsel von sDc3 und sSf6 innerhalb der Fesselungslinie.

Inhalt:
Der Schlüssel verschafft dem schwarzen König ein Fluchtfeld und baut eine Art „Käfig“ für ihn auf. Während der schwarze König in diesem Käfig gefangen ist, nutzt der weiße König diese Zeit, um in einer Art „Querfeldein-Lauf“ auf „sein Feld“ a1 zu gelangen. Nachdem dies geschehen ist, kann Weiß zum „finalen Schlag“ ausholen. Mittels eines Kraftopfers der weißen Dame, wird erstens das Feld a2 geräumt und zweitens der schwarze König in eine weiße Batterie-Linie gezwungen. Dies nutzt Weiß im elften Zuge zu einer Rückkehr des weißen Schlüssel-Turmes. Danach erfolgt noch ein weißes Läuferopfer, sodass der schwarze Bauer mattsetzen muss.
Schwarzes Minimal, Mustermatt.

Kabe Moen: Thank you for the comment and version of my problem. Your version is very nice and more economical. However, the point of my problem was not to show a regular Grimshaw, but to show a distant Grimshaw. The distant Grimshaw happens when a Rook and Bishop mutually interfere with each other on two different squares (d5 and f5 in this case). The section editor also mentions this in his comments on the originals. (2022-07-13)
