MR, der übrigens mit 4/II-III wertete, beschreibt das dargestellte Thema: jedem der vier wThemasteine ist ein Nachbarfeld des sK zugeordnet, welches er ganz allein deckt. In jeder Phase wird jeweils eines dieser Felder durch einen sStein geblockt, der unterwegs zufällig jene Themafigur schlägt, deren Deckungsaufgabe der in Forsberg-Manier sein Kleid wechselnde Stein auf f1 übernimmt. Der Superschnittpunkt T/L/N/(G) ist mir bereits aus einem feenschach-Serienzüger von P.A. Petkov bekannt, der mit einem ähnlich komplexen Zyklus einen Preis errang. Ich wüßte keinen Grund, warum es diesem reichhaltigen Hilfsmatt anders ergehen sollte.
EB: Die vom Autor gewohnten Linienöffnungen mit Matt- und Opferwechsel, hier mit Märchenfiguren garniert.

Das Doppelschrittmatt des f-Bauern wird auf fünffache Art thematisch verhindert.
Verhinderung des Matts durch Schaffung eines En-Passant-Schlags wäre die sechste
