(R. Krätschmer). 1.Sb3? [2.Sa5?] (z. ,B. 1.- Kb7!) und 1.- Tg2#!; deshalb 1.Td6+! Kb7 2.T:b6+ Kc8 3.Tb8+ Kd7 4.Td8+ Kc6 5.d5+! e:d5 6.Sb3 [7.Sa5] Tg2+ 7.Kf5 c4 8.Sa5+ Kc5 9.Lb6. - Origineller gemeinsamer Rundlauf von wT + sK (RJB). Das sind die klaren Themen, die man auch schnell erkennt (HM). Preisverdächtig (KHS). Trotz hübscher Motive wenig aufregend, leider kein Mustermatt (VZ). Bellissimo (LV). MOe: "Auch nur ein mäßiger Mehrzüger. Das Berlin-Thema steht auf logisch tiefer Stufe, da 1.Sb3? auch an der Deckung von a5 scheitert. Auch wird mit groben Mitteln gearbeitet." [Aber auf 5.Sb3? nur Tg2#!. Allerdings würde schon 5.- Tg2+ (z. ,B. -wBh5) mit nachfolgender weißer Beschäftigung ausreichen, vgl. Heft 131, S. ,505, Lösung 7201 ("Pseudo-Berlin-Thema"?). Das potentielle weiße Matt wurde nur von wenigen erwähnt (M3)]. - 2/I;2,5/I-II;4/III.

1. Sc7? (droht 2. Sd5#) scheitert vorerst noch daran, dass der weiße Läufer noch das Feld c7 besetzt hält und außerdem an 2. ..cxd5! Mit 1. Lf4+ gxf4 wird zwar die schädliche Masse des weißen Lc7 beseitigt, das andere Hindernis 2. ...cxd5 bleibt aber bestehen. Außerdem würde nun auch der weiße Sc7 durch 2. ...Dxf7! gefesselt werden. Der schwarze Bc6 muss also vorab nach d5 gelenkt werden, und der weiße König muss die siebente Reihe verlasse. Sofort 1. Kb6? ist noch verfrüht wegen 1 ....Dxf7 2. Lf4+ gxf4 3. Sc7 Dxc7 4. Kxc7 Se6 5. Lxe6 bxa2. Weiß muss also weiter ausholen: Sofort 1. Ta5? (droht 2. Te5#) scheitert aber noch an 1. ...Dg7 und 1. ...Sxf7! 1. Deshalb ist ein weiterer Vorplan nötig: 1. S2f4 (droht 2. Te2#) Te1. Auf 2. Ta5 (droht 2. Te5#) verbleibt Schwarz jetzt nur noch die unzureichende Verteidigung 2. ...Sxf7 (die schwarze Dame kann nicht mehr das Feld f7 erreichen). Nun ist 3. Ta1 was vorher nichts einbrachte) mit einer Drohung verbunden 4. Txe1 Lxe1 5. Te2# Als Verteidigung bleibt nur 3. ...Txa1+ 4. Kxb6 der weiße König hat mit Tempo die siebente Reihe verlassen; nun folgt 4. ...Te1 (Beschäftigung). Jetzt funktioniert alles wie am Schnürchen 5. Sd5+ cxd5 (Lenkung) 6. Lf4+ (Opferräumung) gxf4 7. Sxc7 bel 8. Sd5#
Die weitere inhaltliche Vertiefung des Vorläufers (Problemesis 2001, 7#; vgl. Schwalbe 196, S.511) hat diesem Problem gut getan: alles in allem: ein Meisterwerk der neudeutschen Problemschule!

Aus der Lösungsbesprechnung: 'Der Verfasser hatte die Aufgabe als Darstellung zum Berlin-Thema (das Probespiel scheitert daran, daß Weiß matt wird; durch den Vorplan wird dieses Matt zu einem bloßen Schachgebot) eingesandt - nach der Veröffentlichung aber selbst erkannt, daß dieses Thema hier nicht verwirklicht ist: denn nach 1. Sd4? Le4+ 2. Sc6 genügt es für Schwarz, daß der wS weggelenkt ist, das Mattsetzen kann er sich ersparen.
Der Verfasser legt deshalb eine neue zugleich vertiefte Fassung vor, die thematisch einwandfrei ist.' = P1263505

„Streng logisch bis zum Mustermatt“ (J.Benn, Petershagen-Windheim) geht es in dieser Gemeinschaftsaufgabe zur Sache, denn 1.e4? (2.Td5) L:e6 2.S:e6+ scheitert noch am Gegenschach 1...K:b5+! Die Lenkung des La3 mittels 1.Tc1? ist zu früh, da nach 1...L:c1 2.e4 die Ersatzverteidigung 1...Lh6+! bereitsteht. Deshalb blockt 1.Tg1! (droht 2.Tg5) das Feld h6 1...h6 und jetzt funktioniert 2.Tc1 (3.T:c2) L:c1 3.e4 (4.Td5) L:e6 4.S:e6+ und nun ohne Gegenschach 4...K:b5 5.Td5+ Kc6 6.Sd8 mit Mustermatt (4 Punkte) „Ganz versteckte Begründung des Schlüsselzuges (...Lh6+), dann noch das Turmopfer und der Mustermatt-Abschluss – eine knifflige, aber nicht zu schwierige Aufgabe. Prima!“ (J.Schottenhamel, Ebersbach)

The marvellous quiet sacrifices, 3.Ra4 and 5.Ra4, are needed to keep Black on the go and the bK away from a6. Beforehand the bR has to be lured off the 7th rank by an acceptable option key: White mustn?t neglect the cover of f4.

Henrik Juel: Very little, if any, retro content.
Should not '& 0-0-0 unzulässig' be added in part b) (and similar in part c))? (2013-10-09)
A.Buchanan: I agree this isn't retro. Basically it says we must solve for each consistent combination of rights. Is this termed "RV"?
The stip for b) & c) includes "nur" = "only". I think that's sufficient to indicate what's afoot. (2022-09-13)

During the judgement process the value of this problem rose slowly, but surely. A clear-cut problem of the logical school of composition and a pleasure to solve. The black rook is decoyed to the 6th rank by quiet moves.

Vertiefen Sie sich bitte in die Stellung: Nur ein Stein kommt nach Vorbereitung für den Mattstreich in Frage. Bei Schwarz hingegen kann nur ein Stein ziehen. Dies nutzt der "Fluchtschutz" (Autor) mit Entfesselungen im Gefolge.

Der Schlüsselzug schaltete zunächst zwei Bewacher von Mattfeldern aus. So musste Schwarz notgedrungen eine andere Verteidigung ersinnen, die aber auch eine Blöße gibt. Das Finale folgt mit Donner und Blitz.
