Duplicate Diagram: P1081291

SCHRECKE: Unlösbar (2021-08-10)
HBae: Vermutlich muss der Te4 weiß sein. (2021-08-10)
Mario Richter: Im Orignaldiagramm ist der Te4 tatsächlich weiß, zusätzlich steht auf c6 kein Läufer, sondern ein weißer Bauer (allerdings auch dann mehrfach nebenlösig, speziell geht nach 1. Ta7 g3 neben 2. Ta3+ auch 2. Kg1! g2 3. Lg3 Kxg3 4. Dh5 f3 5. Ta1 (oder ein anderer neutraler Wartezug) f2#; und wie dieses Abspiel zeigt, entfällt die Notwendigkeit, den wTh7 bis nach a7 zu führen [damit später die wD auf die b-Linie kann], so daß auch 1. Tb7! und 1. Td7 lösen). (2021-08-11)
Mario Richter: Interessant: Frank Müller hat ziemlich zeitgleich sowohl diesen Eintrag P1261187 (2013-01-27 22:36:13) als auch P1081291 (2013-01-27 22:37:10) editiert, evtl. hat es also tatsächlich eine Korrekturversion gegeben - hat jemand Zugriff auf den Preisbericht, der Ende 1975 oder im Jahre 1976 erschienen sein dürfte?

Henrik Juel: But the threat is unique, 1.b8=D thr. 2.Dc3+ Ka6 3.Da7+ Dxa7#, and 1... Dxc7 does not prevent this threat, so other continuations that work are not considered duals in my book (2023-04-11)
SCHRECKE: But Black must move and 1. ... Dxc7 is the only one. (2023-04-12)
Henrik Juel: You are right, Michael
This is a tricky case, but I still would consider the problem correct (2023-04-12)

Zwei unterschiedliche weiße Figuren geben das finale Matt auf b2.
Somit Funktionswechsel zwischen den beiden Protagonisten (Sb6 & Tf7 = Deckung / Opfer).
Miniatur.
Schwarzes Minimal. Zweimal Mustermatt.
Rainer Staudte: Das finale Matt gibt der schwarze Bauer, nicht die Protagonisten. (2024-01-11)
