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."

Eine D würde den Schwarzen patt setzen; T u. S. lassen den K nach d6 entweichen, also 1. f7-f8=L. Dadurch wird dem K das Feld d6 genommen und Te8 preisgegeben. ... Mit dem Bauern in die Dame zu gehen, ist nicht immer der stärkste Zug."

Solution:

2) Proof da legality of the answer:
Retro: 0... Ka7-a8 -1. b7-b8=L etc (2009-09-06)
Sally: Der letzte weiße Zug von Weiß kann nur Ba7xb8L gewesen sein, demgemäß enthält die Aufgabe 2 Bauernumwandlungen
in verschiedenen Figuren: in der lösung in einem turm und retrospektiv in einen Läufer.
406 Mattaufgaben mit 3 und 4 Steinen (Teil 1) Speckmann 1976 (2016-08-30)
Henrik Juel: There is even a third promotion in the threat 2.c8=D+
C+ by Popeye 4.61 (2016-08-30)
A.Buchanan: Here the threat play (1) is sound & (2) can never occur as Black has no neutral move. But if threat play is *unsound* yet can never occur, can it be safely ignored or will some directmate purists regard that as a defect? (2022-04-02)
Henrik Juel: I think not, Andrew
When I test problems, I ignore plays that do not occur (2022-04-02)
