Lösungsbesprechung: “Der Autor erweitert eine lang bekannte Mattführung durch ein frühes, überraschendes L-Opfer. Hat seine Daseinsberechtigung, doch eigentlich müsste es heißen: ‚nach C. F. Jaenisch‘, P1171799 von 1837!” [BK] Die Ursprungsidee ist sogar noch älter: “Die zweitlängste Darstellung des 1-Springer-Idealmatts in der Ecke. Es gibt viele Bearbeitungen dieser Mattführung, zuerst gezeigt als #5 im Manuskript 'Bonus Socius' vom Ende des 13. Jahrhunderts (P1129965 oder P1156023). Den Rekord hält die P1124546 von Günther Jahn 1983 mit 16 Zügen! Ansonsten sind mir nur Fassungen bis zu 10 Zügen bekannt.” [Klaus Funk] Eine “schöne Miniatur” [BL], “bei der sogar der wL noch geopfert werden kann!” [JB]

Vergleiche aber auch P1313738.

Asymmetry, but not very striking because of the proximity to the a-line
Still a very nice problem, which is solvable by hand (2021-02-07)
A.Buchanan: Nice to have an empty board for the nightriders to canter around in unblocked. That they are line pieces makes the uniqueness of the solution even more impressive. Someone must have already done tablebase for this endgame (2021-02-08)

(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.
