Frank Müller: Die Stellung ist im Vorwärtsspiel C+. Gleichwohl ist die Stellung retroanalytisch nicht erspielbar, da Schwarz keinen letzten Zug hat. Man kann vermuten, dass der Autor dies übersehen hat.
Um allen Diskussionen aus den Weg zu gehen, habe ich c+ und cooked gelöscht.
Mario Richter: Schwarz hat keinen letzten Zug, müßte also eigentlich in der Lösung beginnen. (2010-11-07)
Olaf Jenkner: Sollte auf Cooked und unlösbar gesetzt werden. (2010-12-31)
Frank Müller: Die Aufgabe ist im Vorwärtsspiel korrekt, erfüllt also die Forderung. Das die Stellung retroanalytisch nicht herleitbar ist, ist sicherliche eine (deutliche) Schwäche des Problems, aber deswegen wird die Aufgabe nicht unlösbar. Ich habe jedoch das Keyword illegale Stellung hinzugefügt. Dies kennzeichnet wohl am Besten die Unsauberkeit der Aufgabe. (2010-12-31)
Olaf Jenkner: Die Stellung ist legal und in Fällen, wo die normalerweise anziehende Partei aufgrund retroanalytischer Überlegungen nicht am Zug sein kann, zieht automatisch die andere Seite. Damit wäre die Autorlösung fehlerhaft und es existiert keine korrekte Lösung. Allerdings kenne ich den Kodex nicht so gut, aber es gibt da ausgewiesene Experten, die sich um viel kompliziertere Dinge kümmern. (2010-12-31)
HBae: Das sollte der Autor korrigieren durch einen anderen Schlüsselzug (mit wKc1 in der Ausgangsstellung). Letzter schwarzer Zug wäre dann Kf1-e2 gewesen. Ich hätte einen akzeptablen Vorschlag (C+), möchte dem Autor aber nicht vorgreifen. (2010-12-31)
Mario Richter: Die Labels 'C+' und 'illegale Stellung' behagen mir nicht - beide sind eigentlich falsch. Dummerweise ist hier wie an vielen anderen Stellen auch der Codex ziemlich schwammig formuliert (leider), trotzdem mal die relevanten Stellen:
"Article 15 - First Move: If the first move does not lie with the conventional party (examples see Footnote 9), this should either be indicated in the stipulation or deducible from retroanalysis. ...
Footnote 19: ... The number of moves to be expressed in the stipulation should be the number of moves to be made by White." (2011-01-08)
Anton Baumann: mögliche Korrektur: +wBa5, +sBa6 (2023-12-22)
Vaclav Kotesovec: Judge Christer Jonsson excluded this problem from the award (see Sachova skladba 111/2011, p. 2770), so I removed "1. Lob". (2023-12-22)
SCHRECKE: Den Vorschlag von HBae aufgreifend, wäre die Aufgabe ohne zusätzliches Material zu retten:
wKc1, wTe5 nach e8 - 1. Te5! (2023-12-22)
