7.Bg2 Kd2#

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.

Lösungsbesprechung: Tschumakow mit Umnoweffekten. "Aus der indirekten Fesselung des sSc4 wird eine direkte. Boros-Thema?" [KHS] "Boros-Thema mit zwei Mustermatts." [HK] "Ich hatte auch in der zweiten Lösung das Fesselungsmotiv erwartet." [ES] "Der sK ist schon vom Stand weg fast eingemauert." [CG] BK schlägt dem Autor eine um 2 Steine abgespeckte Version vor: h#3, 2 Lös., W.: Kb8 Te8 La7 (3), S.: Kb3 Db2 Ta3 Le6 Sa4 Bc5 (6).
Diese Fassung akzeptierte der Autor in Gaudium 254 (28/02/2022), Seite 4. Nur diese Fassung nimmt am Informalturnier teil (das Diagramm und die Lösungen sind bereits korrigiert).

„2 x 3-fache konsekutive Rückkehr von sSc8 und damit laut PDB Erstdarstellung“ (Autoren). „Originelle Inszenierung zweier analoger Springerausflüge mit Rückkehr“ (KR). „Toll! Zweifache Rückkehr – habe ich so noch nicht gesehen“ (HR). „Da hat sich die Elite getroffen“ (WaM).

(MD1825)

Rolf schreibt dazu: Zweimal dreifache konsekutive Rückkehr von sSc8 (und damit, laut PDB, Erst-Darstellung), auf verschiedenen Wegen, mit Beseitigung weißer Masse (g3/h4) zwecks jeweils zweimal Linienöffnung für den weißen Turm, davon je einmal nach Hinterstellung weißer Turm/schwarzer Springer. Verschiedene Wege des weißen Turmes von h3 nach b7. Identisches Mustermatt. Identische weiße Züge eins bis drei; aber alle (!) fünf ZWEIfachen konsekutiven schwarzen Rückkehren in der PDB (alle mit jeweils VERSCHIEDENEN schwarzen Thema-Figuren) haben in allen (!) Lösungen sogar identisches weißes Spiel von Anfang bis Ende, also in allen SECHS Zügen! :-) - DOPPEL-Setzung der EINphasigen P1396043, vom November 2021.

Vergleiche P1405473.

19249 (Frank Fiedler, Silvio Baier, Norbert Geissler & RolfWiehagen). I) 1.– Sc1 2.Tf7? d7 3.d:c1=L d8=D 4.Lg5 Dd1+ 5.Tf3!, 1.– Sc1 2.Te7! d7 3.d:c1=L d8=D 4.Lg5 Dd1#, II) 1.– Sg1 2.Te7? d:e7 3.f:g1=T e8=S 4.Tg5 Sf6+ 5.D:f6!, 1.– Sg1 2.De7! d:e7 3.f:g1=T e8=S 4.Tg5 Sf6#. Lassen wir zunächst das Autoren-Quartett zu Wort kommen: „Gemischte AUW, Voraus-Opfer des wS (11. WCCTThema), thematische Auswahl im ersten schwarzen Zug,Mustermatt. Im 11.WCCT gibt es das folgende Vergleichsstück, dem gegenüber unter anderem die Zug-Wiederholung 2.– f:e7 vermieden werden konnte.“ Wir sehen eine „schwarz-weiße Allumwandlung“ (JB), genauer gesagt „Mustermatts, gemischtfarbige Allumwandlung, schwarze und weiße Opfer, Phönix (Dame und Springer von Weiß), gute Materialnutzung. Gefällt.“ (KHS) „Ein weiteres Schmuckstück und – angesichts der Firmierung – ‚Viele-Väter-Problem‘ aus dem Umfeld des WCCT mit verzögerten weißen Springeropfern und der Begründung, dass ein weißer Bauer vor Opferannahme erst flottgemacht werden muss.“ (RJ) „Die einleitenden aktiven Springeropfer (vgl. z. B. P1100473 & P1402302) und die Nutzung der schwarzen Umwandlungssteine zum Block auf demselben Feld verhalfen der AUW schon in der Bezugsaufgabe (s.Diagr.: I) 1.– Sc1 2.Le7 (2.Te7?) f:e7 3.b:c1=L (3.b:c1=D?) e8=D (3.– e8=S?) 4.Lg5 De2#, II) 1.– Sg1 2.Te7 (2.Le7?) f:e7 3.f:g1=T (3.f:g1=D?) e8=S (3.e8=D?) 4.Tg5 Sf6#) zu einer wohltuenden Einheitlichkeit, die die Aufteilung auf zwei schwarze Themabauern souverän übertüncht. In der vorliegenden Fassung fällt allerdings die Dualvermeidung zugunsten eines nur einphasig vorhandenen Versteckzuges des räumenden Turmes einfach weg, so dass ich die Neubearbeitung bei aller Anmut für einen Rückschritt halte. In dieser Form bleibt es im Wesentlichen nur eine (zugegeben recht hübsch) verlängerte Ausgabe der eigentlichen Urfassung von W. Stjopotschkin.“ (MRit) „Elegant konstruierte, gemischtfarbige Allumwandlung in Opferminimal-Form, aber zu den ‚Verführungen‘ fällt mir hier nichts Gescheites ein?!“ (HJä) „Diese AUW wurde von G. Jordan schon in die PDB gestellt und wurde dort mit einer interessanten Bemerkung von Y. Bilokin kommentiert (er ist der Meinung, dass die Umsetzung der Idee von S. K. Balasubramanian & S. Manikumar in ihrer Aufgabe ‚more meaningful‘ dargestellt wurde – MD), denn die Dualvermeidung ist beim Original viel deutlicher. Von Verführungen im h# halte ich nichts.“ (BK) Daran anknüpfend soll hier die ausführliche Meinung von RJ wiedergegeben werden: „Übrigens sehe ich die bei Hilfsmatts nun häufiger auftretenden v-Angaben unter den Diagrammen eher kritisch. Bezieht sich das ‚vv‘ hier auf die ersten schwarzen Züge? Dann hätte es noch weniger mit einem ‚vv‘ gemeinsam, was man von Direktmatts her kennt. Ehrlich gesagt habe ich bisher bei keinem Hilfsmatt solch eine v-Angabe als wirklich überzeugend und vor allem auch als notwendig empfunden. Das Themengemisch dieser gelungenen Aufgabe inklusive seiner diversen Auswahlmöglichkeiten für Weiß und Schwarz scheint mir jedenfalls auch ohne das ‚vv‘ verständlich zu sein. Die Aufgabe wird nicht besser dadurch, und den Löser – salopp gesagt eines Rätsels – von Vornherein auf besondere Feinheiten desselben hinzuweisen und ihm so eine gewisse eigene Denkleistung und analytische Sorgfalt schon wieder abzunehmen, halte ich persönlich für fragwürdig, sogar im Direktmatt. Auch wenn ich selber schon bei komplexeren Problemen solche v-Angaben vereinzelt befürwortet habe, stellt sich mir generell die Frage, ob ein Schachproblem letztlich nicht für sich selbst sprechen sollte?Wenn seine Intention durch die Komposition klar und deutlich wird, dann erkennt doch ein etwas geschulter Löser i. d. R. auch die verführerischen Abwege klar und deutlich. Wenn letztere aber klarwerden, wozu braucht es dann noch die v-Angabe unter dem Diagramm? Die Antwort darauf sollte doch sicher nicht lauten, dass vor allem unklare Probleme (was bei 19249 keineswegs der Fall ist!) den Löser so noch auf ihre Inhalte mit der Nase stoßen können. Und wenn den Autorinnen und Autoren selbst eine besondere Betrachtungsweise ihrer Aufgabe wichtig sein sollte, könnten sie dafür nicht die Lösungsbesprechung verwenden? Das aber nur einmal als Randgedanken; die Aufgabe selbst gefällt mir natürlich sehr gut!“ (RJ) Die Autoren hatten gleichzeitig mit der 19249 noch eine zweite Fassung eingereicht (s.Diagr.: I) 1.– Sc1 2.Se7? f:e7 3.b:c1=L e8=D 4.Lg5 De2+ 5.Dg4!, 3.– e8=S 4.Lg5 Sf6+ 5.L:f6!, 1.– Sc1 2.De7! f:e7 3.b:c1=L e8=D 4.Lg5 De2#, II) 1.– Sg1 2.De7? f:e7 3.h:g1=T e8=S 4.Tg5 Sf6+ 5.S:f6!, 3.– e8=D 4.Tg5 De2+ 5.Tg4!, 1.– Sg1 2.Se7! f:e7 3.h:g1=T e8=S 4.Tg5 Sf6#. Zusätzlicher Versuch: 1.– Sc3? 2.S:f6 Sd5 3.Se4 (3.Sh7?) Kb1 (einziges Tempo) Se4-g5+ Sd5-f6??#, 2.– Se4 3.Sh7 (3.S:e4?) Kb1 4.Sh7-g5 Se4-f6??#), die sie – bei aller Ähnlichkeit zur E34, speziell auch der Wiederholung des wB-Schlags – ebenfalls als publikationswürdig ansehen. Unterschiede zur E34: Vor allem der zusätzliche Versuch, bei dem der wS nicht als Opferfigur fungiert, sondern als Fast- Mattfigur, also eine Art „Zilahi“ S/B zwischen Versuch und Lösungen. Ferner Farbwechsel schwarzes Opfer / weiße Umwandlung – sD/wD und sS /wS statt Phönix sL/ sT in der E34. Und Meredith, mit 3 Steinen weniger. Ein anonym bleiben wollender Betrachter der Aufgabe sandte mir eine Version (s.Diagr. P1412442: I) 1.– Sb1 2. d5 c7 3.c:b1=L c8=D 4.Lf5 Dc1#, II) 1.– Sf1 2.Sd5 c:d7 3.e:f1=T d8=S 4.Tf5 Se6# (MM)), „die zwar ein paar Steinchen mehr aufweist, aber im Gegensatz zu den beiden ‚Vier-Männer-Versionen‘ eine echte Dualvermeidung aufweist, keine künstlich hineininterpretierte.“ Möge sich also jeder sein eigenes Bild machen.

It still needs author and source, though (and possibly a twin) (2023-07-24)

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.

check the source name
Henrik Juel: The source name is fine, except that the city of Elsinore is spelled with the danish/norwegian vowel ø:
Helsingør
The stuff in front of Helsingør Skakklub (Elsinore Chess Club) is probably:
Jubilæumsskrift 70 år (using the two remaining special vowels) (2023-08-06)
A.Buchanan: Hi Henrik no it's a different Jubilee: this is a Mongolian composer celebrating the anniversary of the October 1917 revolution. I added it to Sources, but forgot to update the problem itself. As far as the Elsinore version is concerned, I will try to add a Unicode version. It's still convenient to have an accent-free version of the name in order to facilitate search (2023-08-07)
A.Buchanan: I could easily have confused Helsingør (scene of Hamlet) with Helsinki (not scene of Hamlet). (2023-08-07)
Henrik Juel: Thanks for clearing up the source mess, Andrew
I did wonder why a mongolian composer would participate in an obscure danish tourney (2023-08-07)
