Das Problem wurde zuerst mit drittem Zwilling (wDg5>h1) und mit Co-Autor Yuri Paramonov in SuperProblem 04/2019 veröffentlicht.
Aber die Lösung war dualistisch:
c) 1. d7-d8=D! Kf7-g6 2. Dh1-h7+ Kg6-f7 3. Dh7-h3 Kf7-g6 4. g7-g8=T+ Kg6-f7 5. Dd8-d7+ Kf7-f6 6. Dh3-h4+ Ke5,Kf5 7. Tg8-g5+ Kf6 8. Tg5-d5+ Kf6-g6 9. Dd7-e8+ Te6xe8#

Judge Ivan Soroka 07/2023:
"Again two solutions – with black rook pinned in the diagram position and four promotions of two white pawns. Unfortunately, the author failed to achieve Allumwandlung – promotion of pawns to all four possible types of pieces: QRBS."

Frank Richter: Angesichts Aufgaben wie der P1415726 oder P1391762 mit derselben schwarzen Matrix und ähnlicher Grundidee ist die hohe Auszeichnung zumindest verwunderlich. (2024-03-22)
