Die beiden Autoren machten den Vorschlag, unter das Diagramm das aus dem orthodoxen Bereich bekannte "v" zu setzen. Dies widerstrebte mir dann doch. Ein diesbezüglicher Hinweis im Vorspann mußte genügen.
Autoren: Rehm-Thema, diagonal und orthogonal mit eindeutigen thematischen Verführungen durch den jeweils "falschen" Hinterstein.
AB: Sehr leicht zu durchschauendes Peri-Manöver.
Schwarz-weiße Opferbahnungen nach einleitenden Umschiffungen des jeweiligen wWirkungssteins (HJ).

PAS-Läufer-Hilfsmatt ab dem 4. Zug.

Die letzten 14 Züge sind identisch mit Kardos, P0502947.
Außerdem Selbstplagiat, V. M. veröffentlichte diese Aufgabe bereits 2008 in Schachmatnaja Komposizija (ganz leicht modifiziert, siehe P1080117).
Die Angabe "harmonie 2009" ist unsicher, denn sie wurde dem Hopper Magazine 03 (Zweitquelle) entnommen.
