Da wagten sich wieder mehr Löser heran.
PG: Originelles Pendel, um Zeit zu gewinnen. - AG: Schönes Schmankerl zur Erholung. - WW: Erfrischend. - HM: Leicht, aber nicht langweilig. - DrRJB: Löserfreundlicher Ausklang. - 2,9/II/7

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.

Content
White waiting move in the key. After the black queen has cleared the long diagonal (moving in the right direction), we see a black and white Bristol in the corner. A Herlin (= Peri-Indian) by white. The wKb5 is "gone around " by Bg2-b7-a6, and this interference is then also used by 6.Kf1.
Model mate

The following problem (P0500529) by Viktoras Paliulionis served as a template.
The white waiting move further enhances the content.

18731 (Hartmut Brozus). 1.Ke5 e4 2.Kd4 e:d5 3.Le5 d6 4.Kd5 d7 5.Kd6 d8=D#(IM). „Der schwarze König macht seinem Läufer Platz zum Block und kehrt auf sein Ausgangsfeld zurück, während Weiß seinen Bauern zur Umwandlung mit Idealmatt führt. Recht leicht zu lösen – nur über den richtigen schwarzen Weg zum Erfolg musste man kurz nachdenken.“ (FRd) „Der Klasinc mit Rundlauf des thematischen Königs findet hier eine Elementardarstellung mit Exzelsiormarsch, die ein wenig unter der mangelnden Schwierigkeit leidet.“ (MRit) „Diese Aufgabe habe ich aus Versehen gelöst, als ich verzweifelt versucht habe, eine ähnliche Mattstellung in 18731 zu erreichen. Lustiger Rundmarsch des schwarzen Königs.“ (JS) Auch KHS gefällt das Stück gut.

Inhalt:
Die Verführung scheitert daran, dass kurz vor Toresschluss die sDg3 im Wege steht.
Deshalb muss diese Dame vorausschauend „aus dem Spiel“ genommen werden. Paradoxerweise geschieht dies, indem sie in der Lösung den aktiven Part übernimmt, und die in der Verführung aktive sDe7 übernimmt dieses mal den „passiven“ Part.
Außerdem sehen wir in der Lösung einen Platzwechsel von sDc3 und sSf6 innerhalb der Fesselungslinie.

Inhalt:
Der Schlüssel verschafft dem schwarzen König ein Fluchtfeld und baut eine Art „Käfig“ für ihn auf. Während der schwarze König in diesem Käfig gefangen ist, nutzt der weiße König diese Zeit, um in einer Art „Querfeldein-Lauf“ auf „sein Feld“ a1 zu gelangen. Nachdem dies geschehen ist, kann Weiß zum „finalen Schlag“ ausholen. Mittels eines Kraftopfers der weißen Dame, wird erstens das Feld a2 geräumt und zweitens der schwarze König in eine weiße Batterie-Linie gezwungen. Dies nutzt Weiß im elften Zuge zu einer Rückkehr des weißen Schlüssel-Turmes. Danach erfolgt noch ein weißes Läuferopfer, sodass der schwarze Bauer mattsetzen muss.
Schwarzes Minimal, Mustermatt.

SCHRECKE: Umwandlungsdual (a8T#) im Hilfsmatt ist nicht jedermanns Sache - meine auch nicht! (2022-07-23)
Henrik Juel: so the problem is not C+... (2022-07-23)
Kurt Keller: see keyword "tolerated dual promotion":
"Sometimes, the mating move is a promotion, and both D/T would mate. Similarly, sometimes D/L would both work. This is a tolerated dual under Article 13 of the Codex, because if it were not allowed, too many matrices would be invalid."
Article 13 (https://www.wfcc.ch/1999-2012/codex/):
"(2) Help-play compositions are unsound also if they are dualized, except that in the final move a promotion into different pieces having partially the same power (for example queen/rook or queen/bishop) may be tolerated [16]."
Therefore, the problem is sound (C+). (2022-07-23)

Henrik Juel: Congratulations, Miguel
This the first correct entry by you, I believe
It still needs author and source, though (and possibly a twin) (2023-07-24)
A.Buchanan: Hi Henrik, we are working to automate the process of uploading these problems. It will take a day or so, after that should be smooth. (2023-07-25)
Miguel Ambrona: Thanks Henrik!
This is a problem I composed a few years ago, before I know about the notion of twin. I may work on it at some point.
