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)
Gunter Jordan: ... entschuldigung, verzählt. Es sind 4 Anfangszüge bei Yuri. (2023-01-15)
