A.Buchanan: Hi Gunter thanks for your scholarship. The specified syntax for PDB is to separate phases by commas. If something only occurs in 1 phase I guess it would be e.g. "L,". It is not a good idea to have multiple occurrences of the same keyword within a problem, because that makes counting & quality-checking more difficult, and is fiendishly difficult to track. Thanks for your understanding. If you have different opinions, please express them here, in German or English. (2022-08-01)

Mario Richter: Hi Andrew, can you please give an example in what sense "multiple occurrences of the same keyword within a problem" do make "counting & quality-checking more difficult", and what you mean with "is fiendishly difficult to track"! (2022-08-04)
Gunter Jordan: Lieber Yuri, wie mir die Autoren mitteilten, kannten sie die von dir angegebene Stellung (und noch weitere Versionen), doch entschieden sie sich bewusst für ihre Diagrammposition, weil darin Weiß nicht nur drei Anfangszüge hat, wovon sogar zwei lösen, sondern eine größere Auswahl in einer viel freieren Stellung. (2023-01-15)

Lösungsbesprechung: Tschumakow mit Umnoweffekten. "Aus der indirekten Fesselung des sSc4 wird eine direkte. Boros-Thema?" [KHS] "Boros-Thema mit zwei Mustermatts." [HK] "Ich hatte auch in der zweiten Lösung das Fesselungsmotiv erwartet." [ES] "Der sK ist schon vom Stand weg fast eingemauert."

Diese Fassung akzeptierte der Autor in Gaudium 254 (28/02/2022), Seite 4. Nur diese Fassung nimmt am Informalturnier teil (das Diagramm und die Lösungen sind bereits korrigiert).

Der Preisbericht erschien in Gaudium 260, 10/06/2022.

PR: "Die beiden reziproken Unterverwandlungen werden mit Hilfe von mehreren Batterien realisiert, die zunächst aufgebaut und danach abgefeuert werden. Dabei legt der schwarze König in beiden Varianten einen weiten Weg zurück, bis er die passende Position erreicht hat. Der Materialeinsatz ist sehr sparsam, wobei der wLg6 für meinen Geschmack dennoch etwas unterbeschäftigt ist. "
