Auszeichnung in Schachmatnaja poesija.
Im Original steht in SPo die wD auf e6 und es gibt einen zusätzlichen wBb3.
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)

Vertiefen Sie sich bitte in die Stellung: Nur ein Stein kommt nach Vorbereitung für den Mattstreich in Frage. Bei Schwarz hingegen kann nur ein Stein ziehen. Dies nutzt der "Fluchtschutz" (Autor) mit Entfesselungen im Gefolge.

„Weglenkungen von schwarzem Turm bzw. schwarzem Läufer führen zur Entfesselung von Turm bzw. Springer. Diese Entfesselungen können für ansehnliche Matts genutzt werden. Gut gemacht.“ (J.Schottenhamel). Das Gegenschach im Satz ist harmlos 1...T:b6+ 2.K:b6 3.Dc6 matt. Die Lösung 1.Lf5!
