Arnold Beine: Dass Schwarz hier - im Schach stehend! - rochieren darf, ist mehr als dubios, zumal - laut englischer Definition - alle Steine, also auch der sTa8, königlich sind. In meinen Augen ist die Rochade hier nicht erlaubt, auch wenn ich mir spitzfindige Begründungen für die Ausführung der Rochade vorstellen kann. (2018-1-15)

play all play one stop play next play all
Lösung aus dem Preisbericht (PR M. Caillaud): If last move was Le2-d1 (other L-moves are illegal because of reflex mate Ke2#), then 0-0-0 is illegal otherwise reflex condition would have forced it as last move. Other last black moves have to be studied, such as -1. Tg8-g5 g5xDh6 -2. Df6-h6 given by composers; but I see no point in this complications : there would have been some point for example in a twin presentation, where a sequence of moves save the castling in a position and not in the other one, but this is not the case here...

play all play one stop play next play all
Lösung aus dem Preisbericht: Black Pawns captured the 10 missing white pieces. Every possible black last move (except King and Ra8 moves that distroy castling) leaves position with mate by castling that should have been played if castling was legal.
PR M. Caillaud zum Grund, warum er diese Aufgabe dem zweiten Beitrag vorzog: "One of the entry [P1348271] added some complications in the retro construction, ending in a much heavier position. Well, it is generally true nowadays than to be on top of an award, you have to display some complexity. But chess composition is not only 'sport' but also 'art'. And clarity of exposition of the idea was here the decisive point."

Mario Richter: Does somebody know the solution? The only legal black last move seems to be e6xQd5, but how does the retroplay continue? (2010-8-17)
Henrik Juel: Before we start looking for the retroplay, we might entertain the notion that the diagram or stipulation is wrong; I base this suspicion on the fact that the forward stipulation (with White to move) has lots of solutions. (2010-8-17)
Gerd Wilts: Diagram is correct, original stipulation was "Reflexmatt (seit PAS) in 1 Zug". (2010-8-17)

N. Bakke versucht sich wieder mit einer logischen r#-Miniatur.
1.Tc5? Te5! 2.Lb5 Te4# scheitert an 1.- e5! Also muß der sBe7 weg, was mit 1.T:e7! ziemlich brutal geschieht, dann folgt ein kleiner doppelter Rundlauf: 1.- Te5 2.Tg7 Te7 3.Tg5 Tg7 4.Te5 Tg5, und nun klappt der Hauptplan: 5.Tc5 Te5 6.Lb5 Te4#.
Wie die anderen Versuche des Autors wirkt das leider wieder sehr spröde: "Der Schlag im ersten Zug ist verdrießlich, und daß der Rundlauf doppeltgesetzt wird, ist gattungsspezifisch fast zwangsläufig." (HHS)
"Turmrundlauf mit sparsamen Mitteln: f5 und g5 dürfen wegen a) weißer und b) schwarzer Verfolgungspflicht nicht betreten werden." (WoW)
"Die Verfolgung im Quadrat mündet nach Doppelselbstblock in ein Idealmatt." (RobS)

Henrik Juel: Popeye 4.65 (with conditions weisserve and schwarzerve) finds the intended solution and reports no solution with stipulation r#4; but Pauls cook seems correct, so Popeye is flawed here (2014-11-4)
Henrik Juel: Correction:
In Pauls solution 4.Lb5 is illegal, since 4.Lf5 is mandated.
So Popeye is correct, while Poursuite in WinCloe seems to apply to Black only (2014-11-4)

(B. D. Stephenson & St. Emmerson). In letzter Zeit basteln die Engländer wieder verstärkt Reflexmatts, und BDS geht noch immer am liebsten zum Chinese take away: 1.- VAb8/VAc7 2.PAf6 VAc7/VAb8#, 1.PAg4! LEb5 2.PAc4 Lc5#, 1.- VAb8 2.Ld5 LEd6#, 1.- VAc7 2.Le6 LEd6#. Das ergibt insgesamt einen doppelten Paradenwechsel. Neue Informationen zur Rasenhöhe in BDS' Garten gibt es nicht, allerdings sprechen Indizien dafür, daß beim Rasenmähen seine Telefonleitung gekappt wurde... 8L/5P

(N. A. Bakke) "ist leider durch mehrere Duale ziemlich lädiert, was bei den vielen wDD ja fast zu erwarten war."

(H. Zajic). Verführungen: 1.Tc-h8? h5! 2.h4? Tc6-h6! 3.??; Lösung: 1.h3! h5 2.h4. Der Autor fragt: Sechsfacher Wladimirow. Rekord? (Beim Wladimirow-Thema werden die Schlüsselzüge der Verführungen nach denselben sVerteidigungen, die in den Verführungen als Paraden auftraten, zu Mattzügen in einer anderen Phase.). Das Zucken in den Mundwinkeln entstand dadurch, dass formal alles korrekt abläuft; der schematische Ablauf gibt freilich zu denken... (GES). 6 x wT-sT-Opposition; der Autor hat eine verblüffend einfache Darstellung gefunden (KHS)! Das Satzspiel wiederholt sich in der Lösung. Nicht gerade tiefschürfend (AB)!

EB: Zwar zwei nette Varianten, aber mit viel Aufwand und ... mit echtem Reflex hat das nichts zu tun. Allenfalls mit dem Semi-Reflexmatt, denn es gibt keine dem echten Reflexmatt typische Möglichkeit für Schwarz bei schlechtem weißen Spiel so zu antworten, dass Weiß reflexgemäß mattsetzen muß. Die Angabe "Reflex" ist also nur Augenwischerei! GES: Recht so, lieber Erich! Aber die Reflexmattbedingung hilft sehr, wenn auch die Bezeichnung "Semi-R#" ehrlicher gewesen wäre!

Diese Aufgabe ist der thematische Höhepunkt der Serie. Ein kompletter 4x4-Lacný!
Fazit: KHS: Ein abwechslungsreiches Angebot!
WW: Eine vortrefflich wild gemischte und sehr schwierige Serie. Nichtsdestotrotz, wie es heißt: mehr davon (auch wenn man nicht alles zu lösen vermag). Früher habe ich mich über die Probleme geärgert, die ich nicht lösen konnte, jetzt ärgere ich mich über die, die sich zu schnell (Computer) lösen lassen. [GES: da hat sich ja einer geoutet!]

Interessanter Mechanismus: während der wK schrittweise auf der a-Linie nach oben steigt, versucht Schwarz durch Bauernzüge das Reflexmatt zu verhindern; der wK als Alleinunterhalter (KHS). AB: Paternoster mit einem in meinen Augen überflüssigen sSe8 [Stimmt! Der SB hatte vor Toresschluss es unterlassen, diesen vom Autor korrigierten Mangel zu beseitigen.]. EB in einer ausführlichen Kommentierung: Paternoster mit 5 Etagen. Allerdings gefällt mir hier einiges nicht: 1) ,um 5 Etagen zu zeigen, braucht man keine Märchenfiguren und auch keine illegale Stellung. [Korrekt; dem Autor kam es allerdings gerade auf die Kombination Rex solus + Paternoster an]; 2) ,Die Reflexforderung (wieder mal nur Semireflex) ist für Rex solus im Matt nicht möglich, wohl aber im Patt [Des öfteren hat EB bereits bei Reflexmatts angemahnt, dass es sich eigentlich um Semi-Reflexmatts (Bedingung "Reflex" gilt nur für Schwarz, nicht für Weiß!) handelt. Während es m. ,E. in diesen Fällen etwas pingelig, aber korrekt von der Definition her, erschien, kann ich EB im Fall der 11455 nur Recht geben: da ein reflexmattgebender wK nicht möglich ist, wäre hier die richtige Forderung "Semi-Reflexmatt" gerechtfertigt. EB legt die Erstdarstellung seines Ser.-r= mit Rex solus vor, das ich den Lesern nicht vorenthalten möchte (siehe Diagramm!). Lösung: nähert sich der wK auf seinem Weg in den sKohlenkasten zu schnell der Brettmitte, dann muss er pattsetzen: 1.Kg2? 2.Kf2=!; deshalb immer am Rand entlang: 1.Kh2! 2.Kh3! (nicht: 2.Kg3? 3.Kf2=!) 6.K:d5 7.K:c4 8.K:d3 d5=]. 3) ,Die Unzahl von Mattdualen sind nach meinem Empfinden ganz einfach grässlich, wobei mir bewusst ist, dass ganze Heerscharen jetzt schreien, im Reflex seien dies Varianten [also lieber EB: stimmt; aber der Autor und GES schreien jetzt im Chor: ... ]. endwindow
