Erich Bartel: Auszeichnung: 1.ehrende Erwähnung.--
Nachdruck: 1) Jaarboek 1970.-- (2006-11-26)
Henrik Juel: Something is wrong: De5 does not mate. And the intention certainly was not -1.S=a7 L=h2, 0... Kxc5 1.h8DL Kb6 2.DLd4#. (2006-11-27)
Erich Bartel: Ich habe die Aufgabe aus dem Jaarboek 1970 übernommen, wo
sie wie angegeben im Diagramm und Lösung so steht. Es
scheint also bereits hier ein Fehler vorzuliegen. Zur Klärung
ist es wohl notwendig in der Ur-Quelle Probleemblad -die ich
nicht besitze- nachzusehen. (2006-11-27)
Siegfried Hornecker: No matter how the position is changed, there can be no line where the king, coming from b6, is not allowed to return to b6 when the queen checks on e5. Also, there would be no reason to not play again 2.h2-h1~ as a waiting move.

The retroanalytics say that the last move must(!) have been 1.a7-a8S+ h2-h1L so I think the correct stipulation is:
a) Last move (w+s)
b) h#2

I have no source for this but if you think about it, the whole thing makes sense! The last move was 1.a8=S+ after 1.h1=L and from the diagram position the h#2 runs 2. Kxc5 h8=D 3. a1=T De5#. That's what I think. (2006-12-12)
Jan Hein Verduin: I got the Jaarboek too, and mr. Hornecker is right. The stipulation there is "h#2; what where the last w+b moves?" The way the solution then is given (the retro moves are given first) probably caused the confusion. (2007-01-26)
Adrian Storisteanu: Then, ceci n'est pas un ... retractor!? (2024-03-17)
Henrik Juel: Right, Adrian
The Help retractor keyword should be deleted (2024-03-17)

Die Rollen der fesselnden und gefesselten Figur werden umgedreht. Grimshaw auf f3 und Funktionswechsel von T und L
Sally: Markant ist der Grimshaw auf "f3" (überraschend auf einem "Eck-Feld" des w. Königs), wobei die dennoch notwendige Fesselung prägend ist. [Eine der ersten Aufgaben des Erfolgsduos].

Diagonalmarsch des schwarzen Königs von Ecke zu Ecke, in Miniaturform.
Diese Idee ist natürlich nicht neu, aber laut PDB sind mehrere Merkmale neu, nämlich:
Der weiße König von g2 muss weit weg (g5) von seinem Zielfeld gehen (f2), mit doppeltem aufeinanderfolgendem Switchback, die weiße Batterie feuert ZWEIMAL und in GEGENSEITIGE Richtungen, Klasinc wK/wB (f3), Tempo vom weißen Bauer.
Sowohl der weiße Inder als auch der schwarze Durbar wurden bisher nur EINMAL gezeigt, beide in P0501643, veröffentlicht in Probleemblad.
Das Schlagen der weißen Dame im Schlüsselzug wurde zweimal gezeigt, in P0501414 und in P1364909, letzteres auch in Probleemblad - Sie sehen, dass Probleemblad bereits eine gewisse Tradition in diesem Thema hat, was für uns der letzte Grund war unser Stück nur Ihnen anzubieten! Schließlich gibt es in der PDB drei Miniaturen zu diesem Thema, P0522184, P1005185 und P1364529.
Inder, Durbar und Miniatur sind zwar nicht neu, aber all das zusammen in ein und demselben Stück ist auch neu.
