Nachträglicher Kommentar des Autors: Der sBc4 kann entfallen.
Auch veröffentlicht in "KSG-Problemschach 1969-1987".

Der Autor nimmt die Idee von Mario Richter dankend auf und korrigiert sein Stück mit der zusätzlichen Bedingung Single box. Im neuen Diagramm ist auch der überflüssige sBc4 entfernt worden. Die Erstveröffentlichung dieser Korrektur ist die PDB-website am 17.05.2023.
Cook: Falls nicht eine Bedingung (z.B. single-box) fehlt, gehen auch
R: 1. Bd2xSc1=D+ Se2xSc1

Stefan Felber: Kein Modellmatt! (2023-10-27)
Gerald Ettl: Warum soll das kein Mustermatt sein? Fuer mich ist es eins. (2023-10-28)
SCHRECKE: Das Feld h4 ist geblockt+gedeckt! (2023-10-28)
Gerald Ettl: geblockt macht nichts aus, nur wenn es 2-mal von Weiss gedeckt ist, dann wuerde es was ausmachen. (2023-10-29)
SCHRECKE: Die Definition des M. lautet: "Mattbild, bei dem alle weissen Figuren ... mitwirken und jedes Feld um den schwarzen König nur einfach gedeckt oder geblockt ist."
Jedes Feld darf also nur aus einem (!) Grund für den sK unzugänglich sein und das ist nicht der Fall. Hier liegt definitiv kein M. vor ... (2023-10-30)
Gerald Ettl: Danke Schrecke, das war mir auch neu. Ausserdem habe ich nochmal bei ein paar Schachfreunden nachgefragt, die sind auch der Meinung, dass es kein Mustermatt ist. (2023-10-30)
Henrik Juel: for what it may be worth: I also think that there is no model mate here (2023-10-30)
