vf: Oskar Rittershofer, 15.11.1972, Schach-Echo

Zum Autor schreibt 'Schachsport': "Rund 17 Jahre lang (etwa 1955-1972) hat Gerald Sladek, Vöest-Angestellter, Schachprobleme produziert; Aufgaben, die größtenteils Aufsehen erregten und ihm national wie international Anerkennung und zahlreiche Turnierpreise einbrachten. In seiner Glanzzeit zäh1te Sladek zu den führenden Komponisten unseres Landes, manche seiner raffiniert-verschmitzten Aufgaben wurden von den Ratefüchsen für unlösbar gehalten - das ist Qualitätsbeweis genug.
Im Heft 5/86 von 'Schach+aktiv' hat F. Chlubna den ganz individuellen Stil des Linzer Meisters treffend wiedergegeben.
Obwohl auch Sladek Mitbegründer der 'Linzer Problemrunde' war und nebenbei zwei Problemspalten in angesehenen Tageszeitungen redigiert, ist er - seit 1972 - leider nicht mehr 'problemaktiv' geworden.
Ob der einstige 'Problemlöwe' - vielleicht im Ruhestand neu motiviert - wieder 'rückfällig' werden kann?
Die Problemwelt wäre sicher dankbar; diesbezügliche Anstrengungen werden auch von seiten der Linzer Problemrunde - bisher leider vergeblich! - unternommen."

vf: sLb7->f3, gleiche Autoren, 24.03.1866, Leipziger Illustrierte Zeitung (s. P1067308)

In der AZW mit folgender Forderung veröffentlicht: "Weiß hat Matt in vier Zügen angekündigt, Schwarz behauptet, daß dies nicht möglich sei. Wer hat recht?"

Die Aufgabe hat vermutlich S.Loyd zu seinem "Stuck Steinitz"-Problem (P1055026) angeregt, s. A.C.White in "Sam Loyd and his chess problems", S.321: "Probably the most famous of early Stalemate Tries is an amusing little five-mover by Kohtz and Kockelkorn, which Loyd very possibly had in mind."
