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)

Die Schwalbe 12/2013
MRi: "Nach dem ersten, naturgemäs schlaglosen Zug muss Weiß im Rest der Partie permanent schlagen. Dass sich gleich drei weiße Steine aktiv an dieser Fresserei beteiligen, kommt ebenso überraschend wie der Schnoebelen-Läufer auf h8, den man beim bloßen Blick auf die Endstellung wohl kaum erwartet hätte. Netter (Computer?!)-Fund im Bereich der At-Home-BPs."
HG: Siehe Kommentar zu 15609; hier mit Schnoebelen-Läufer, sK-Rückhehr und sD-Opferzug."
SBa zu 15069 und 15611: "Das dürften die ersten orthodoxen Doppelhomebase it Schnoebelenumwandungen sein. 156909 ist inbesondere weben des genialen Tempozugs Ke7, der die eigentliche Begründung der Umwandlung liefert, viel besser, die andere errinerte eher an Massakerbeweispartien, Nichesdestotrotz will das erstmal konstruiert sein.
