Only two #3s this time, and no excessively long moremovers. [...] Keller presents with New Year greetings a symmetrical Christmas tree – but the 2 variations are not symmetrical.

Der Preisbericht erschien in Gaudium 260, 10/06/2022.

PR: "Die beiden reziproken Unterverwandlungen werden mit Hilfe von mehreren Batterien realisiert, die zunächst aufgebaut und danach abgefeuert werden. Dabei legt der schwarze König in beiden Varianten einen weiten Weg zurück, bis er die passende Position erreicht hat. Der Materialeinsatz ist sehr sparsam, wobei der wLg6 für meinen Geschmack dennoch etwas unterbeschäftigt ist. "

(MD1905)

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.
