Die Mattchancen aus dem Plural des Drohspiels virtuell wiederholen sich step by step im Singular reell. Beides zusammen: ein feiner Circum-Fleck des Hamburger Thema-Spezialisten (FH). Direkte Entfesselung der wD erweist sich als zu grob, doch nach dezentem Vorgehen wird diese doch (indirekt) entfesselt, wonach die Drohmatts der Verführung einzeln doch verwirklicht werden. Gut konstruiert und originell (MOe). Good change of play: Fleck theme in the try with separation of mates, and reappearance of these after of the wQ unpinned in the solution (EP). Überraschender und schwieriger Schlüssel (EG).

Nightrider: Why is the original position not given here in the diagram?
I don't think that the author would be pleased to see his problem in a version with unprovided checks (1...Qxa7+, 1...Rxa3+, 1...b6+, 1...Sc4+), which he avoided carefully: He placed the wQ on e6 so that a battery check by the bBb5 could be answered by 2.Qe5+ and the black correction 1...Ba4+ could be answered successfully by 2.S3b5+ - thanks to the wP that he placed on b3 (so that wQe6 could not capture bRa2). It is obvious that the author took pains to avoid unprovided checks. (2022-10-13)
