Chess problem / Schachproblem

Johannes Kohtz und Carl Kockelkorn, München 1911, "Eine Schwalbe": Matt in 4 Zügen

Das Diagramm wurde mit dem Programm ChessBase 8 der Firma ChessBase GmbH (Hamburg) erzeugt.

Meine explizite Nachfrage bei der Firma ChessBase wurde am 19. Februar 2005 beantwortet:

es gibt keinerlei Einwände gegen die Verwendung des ChessBase-Diagramms.
Über die Quellangabe freuen wir uns.

Mit Freundleichen Grüßen

André Schulz

Den typo "Freundleichen" habe ich bewusst nicht korrigiert - tsor
