'DAZ'-Lösungsanalyse: "Den starken Drohungen des Schw. (Dxe8, Tb3-a3,h2-h1=D) kann Wß. nur durch starke Mattdrohungen begegnen. Als solche ergibt sich 1. Sd4-f5, was 2. Da1-h1+ und 2. Da1-a6 (--c6 oder b7) droht. Die stärkste Erwiderung ist natürlich Dh8xa1, worauf Sd7-f6 matt folgen könnte, wenn die D von der Deckung des Feldes f6 abgesperrt werden könnte. Das erreicht aber Wß. durch 2. c2-c4+, worauf Schw. b4xc3ep spielen muß und Sd7-f6 matt setzt. Nun hat Schw. gegen 2. Dh1+ auch die Verteidigung La7-g1, was auch die Fortsetzung 2. Da1-a6 (wegen Dh8-a1) ausschließt. Dann schließt aber Wß. durch 2. e2-e4+ f4xe3ep die L-Schräge und Sd7 gibt auf b6 matt. Nicht minder fesselnd gestaltet sich das Spiel, wenn Bd3 von einem T geschlagen wird: 1. ... Tb3xd3 2. c2-c4+ b4xc3ep 3. Da1-a2 matt und 1. ... Th3-d3 2. e2-e4+ f4xe3ep 3. Da1-h1 matt. In diesem Fall wird durch das erzwungene Kreuzen ['DAZ'-Sprechweise für "en passant-Schlagen"] der betr. T verhindert, zwischenzusetzen. Die Aufgabe, die also mittels des Kreuzens einmal die Sperrung zweier Schrägen, das anderemal die Sperrung einer seitlichen Turmreihe durchsetzt, ist ein Meisterwerk ersten Ranges."
'DAZ' gibt als Quelle "1. Preis Strategie-Turnier 1908" an.
F.Chlubna (s. Ndr. Vers.Schätze) gibt "Ehrende Erwähnung, La Stratégie 1908-09 " an. (db)

Schon der Einleitungszug ist schwerer als sonst, weil er nicht ein sofort erkennbares Matt androht, sondern die Drohung über volle vier Züge erstreckt. Allerdings gibt es gegen ihn, wenn man ihn gefunden hat, nur eine einzige zureichende Verteidigung. Hat man diese entdeckt, beginnt die Schwierigkeit von neuem. Wie nun fortsetzen? Jetzt muß es auf wuchtigere Art geschehen. Aber vor dem Schlußzug kommt dann doch noch ein stiller Zug.

Im Original steht auf g6 kein sB.
Bei den Lösungen in der 'SASZ' 02/1967 S.29 heißt es: "Der Hauptplan 1. Tb5, Ld6 2. Te5+! L:e5 3. d5# stößt auf das Hindernis 1. Lc5! Weiß gelangt daher nur zum Ziel, wenn er durch ein direktes Manöver (Führung des Turmes) eine vollständige Umgehung des Schnittpunktes c5 vornimmt: 1. Tb7! Ld6! (1. Lb4 2. d5 3. T:L 4. d:e6 5. Te4#) 2. Td7 Zugzwang Lb4 (a3) 3. Td5 usw. Um nach 3. Ld6 die Dual-Möglichkeit 4. Tf5 auszuschalten, fügen wir der Diagramm-Stellung einen sB auf g6 hinzu." [Gfeller war zu dieser Zeit Leiter der Problemrubrik der 'SASZ', das "wir" deutet also auf eine Korrektur des Autors selbst hin.]

Im Preisbericht der 'SASZ' 04/1967 S.46 dann mit sBg6 und der Problemnummer "3096 V".

Zu dem Buch 'Kunstschach in der Schweiz' existiert eine von Hans Henneberger erstellte Errata-Liste, in der es zu diesem Problem heißt:
202) H. Gfeller

Henrik Juel: double threat 2.Dxa5+,Lxd3, many duals and mate duals (2022-10-04)
Ulrich Voigt: Ist eine Drohung, die aufgrund von Zugzwang nie verwirklicht werden kann, tatsächlich eine Drohung? Es gibt keinen schwarzen Zug, nach dem 2. Lxd3 zum Ziel führt. Kann man in einer solchen Situation überhaupt von der Drohung 2. Lxd3 sprechen?

Die einzige "echte" Drohung ist 2. Dxa5, und nach den beiden Paraden 1... Kxb5 oder 1... Lxb5 findet Popeye keinerlei Duale oder Mattduale. (2022-10-05)
Henrik Juel: I agree that 2.Lxd3 is a threat only in a formal sense, Ulrich
If you disregard it as a threat, the problem is OK (2022-10-05)
