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.

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.

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.

18799 (Mykola Wasjutschko & Mykola Tschernjawskij). a) 1.Lb3 c:b3 2.Lg1 b4 3.h1=T b5 4.Th2 b:c6 5.Ta2 c7 6.Ta7 c8=D#(MM), b) 1.Dd3 c:d3 2.Ld1 d4 3.c2 d5 4.c1=T d6 5.Tb1 d7 6.Tb7 d8=D#(MM). „Zwei Exzelsiore, schwarzer Schachschutz, Turmunterverwandlungen und Selbstblocks. Auch die Echomatts sind verbindende Elemente dieses vorzüglichen Zwillings.“ (GJ) So richtig als Echo würde ich die Matts wegen der verschiedenen Blockzahlen nicht ansehen, aber sei es drum. KHS sieht „Mustermatts, Exzelsiormärsche, schwarze Opfer, schwarze Turmverwandlungen. Die umgewandelten schwarzen Türme blocken je ein Fluchtfeld. Alles ist so ähnlich schon dagewesen (in meiner dunklen Erinnerung). MRit wird sicher wieder genügend Vorgänger herausfischen.“ Auch HJä vertraut ihm: „Exzelsiormärsche und -matts des weißen Bauern und schwarze Umwandlungen für je einen notwendigen Turmblock in sparsamer Konstruktion; dass sich bei diesem populären Thema wohl einige Vergleichsstücke zitieren lassen werden, wird MRit vermutlich noch belegen“. Der äußert sich allerdings nicht dazu, sondern schreibt lediglich: „Wandert der Bauer links herum, wird der weiße König auf der rechten Seite gegen die Umwandlung des Blockturms abgeschirmt und umgekehrt. Dabei beeindrucktmich besonders die unscheinbare Zwillingsbildung“.
