In 'My Life' steht als Originalquelle "Games 1996" - welche Publikation damit gemeint ist, ist unklar. In den Index-Files des 'Games and Puzzle Journal' [Jelliss] taucht der Name Benkö nicht auf, laut 'Chess Periodicals' [Felice] gab es zwar einige Magazine, die vom Namen her passen könnten (s. S.90ff, Einträge 1016ff), deren Publikationszeitraum aber jeweils weit vor 1990 endet.

Strategems started in 1998, I believe (2016-06-19)
Frank Müller: Die Quelle kann ich auch nicht prüfen. es könnte auch The Games and Puzzles Journal sein. Das gab es zumindest in 1996. (2016-06-19)
Mario Richter: Vielleicht kann jemand mit Zugriff auf alte 'Strategems'-Ausgaben mal schauen, was dort als Originalquelle zu Problem P1000507 angegeben ist - das könnte helfen ... (2016-06-20)

Die Idee mit den Buchstaben SL im Diagramm finde ich super! (2023-05-20)
A.Buchanan: Yes I like the letter idea, which can only work in German. Do you think this was intentionally a non-unique PG? Given the triumphs of the unique PG genre, such problems do not impress, but it wouldn't be "cooked". Or maybe we should classify all non-unique PGs here as cooked? What do you think? (2023-05-21)
Henrik Juel: Testing gives the result 'cooked'
This problem is correct in the sense that all shortest proof games last 17.0 moves
Still the current C+ is rather misleading
I suggest no label, neither C+ nor cooked (2023-05-21)
Moldenhauer: Ich nehme an, dass die Absicht es Sam Loyd zu widmen, das Ziel war.
Deshalb für diese Ausführung C+. Wenn der Autor selbst angibt das es nur
einen Lösungsweg gibt ist die Aufgabe cooked. NUPG haben andere
Schachproblemfreunde festgestellt und als Schlüsselwort angegeben. Oder irre ich? (2023-05-21)
Olaf Jenkner: Machine translation is very poor as far as problem chess is concerned. (2023-05-23)
A.Buchanan: Hi Moldenhauser. Non-unique PGs are uncooked if 1) the move total is correct, (2) the intended theme appears in every shortest solution. For a problem like this where the theme is the final diagram, the second is vacuous. In 1986 some unique PGs were being already published, and I t can be difficult to discern the intention of the composer but I think this one was intended to be non-unique. I don’t think any non-unique PG can be classed as C+. (2023-05-23)
