HBae: Quelle Schwalbe kann ich nicht überprüfen. Besitze aber das Originalheft von problem (133-135) 02/1970 mit Preisbericht von Preisrichter Peter Kniest. Demnach erhielt die Aufgabe mit Nr. 2451 von H. Selb (Stellung nochmal in typis) die 3. ehr. Erwähnung. (2011-01-29)
Frank Müller: In Die Schwalbe 07/1965 Seite 153 ff. publizierte Hans Selb einen Artikel "Doppel-Längstzüger im Rampenlicht". Darin ist auch diese Aufgabe mit der Nr. (7) als Urdruck enthalten. Gleichzeitig wurde das 139. Thematurnier (Doppel-Längstzüger) ausgeschrieben.
Typischer Fall von Doppelveröffentlichung.
Ürbigens, die korrekte Quelle in problem ist: 2451 problem 09/1966. (2011-01-29)
Gunter Jordan: In feenschach, Heft 1, 01/1971, Seite 23, ist die Aufgabe nachgedruckt worden. Über dem Diagramm steht: H. S., 3. ehr. Erwähnung, Problem 1967. Aber um das Durcheinander mit diesem Selbstplagiat perfekt zu machen: Die Aufgabe ist nebenlösig! In feenschach 246, 07-09/2021, Seite 191, seht unter BuB 2/2021 die unter Cook eingetragene NL in 22 Zügen. (2022-12-29)

A.Buchanan: In what sense are the two promotions “konsekutive”? (2021-02-24)
James Malcom: Andrew, it's much less a keyword for consecutive promotions as it is a catch-all for all problems with 2 promotions in them. (2021-02-24)
Olaf Jenkner: "konsekutive" means one promotion after the other, not two promotions in two variations.
Of course in helpmate this doesn't make much sense. (2021-02-24)
A.Buchanan: Hi thanks for this. Let's take a step back. I counted *85* non-fairy keywords which refer to promotion or umwandlung in either name or description! There must be other relevant ones with no descriptions today. A keyword has no value to us until it is accurately populated (a small percentage of false positives and negatives). And it requires substantial work to populate. There is also a lot of overlaps and gaps still, which are harder to distinguish because of the number of keywords and the vagueness of both their intended descriptions and usage. I also want to make as precise as possible keyword definitions and to align with actual usage, so that they can be populated automatically by PDB as easily as possible, and so that different curators can populate data harmoniously. So less is more, and then we can fill any gaps that remain. The data doesn't have to be perfect right off, but we should have a path for convergence over time.

"Promotion" can be the catch-all vanilla keyword to track promotions where the promoted officer can be identified, e.g. promotion(Sd) or promotion(x2 Sd). Separate different phases by comma, as usual. “Consecutive promotions” can then return to its intended usage as a thematic keyword identifying a run of promotions as close together as possible. The count shifts to the parameter field rather than part of the keyword itself e.g. not “consecutive promotions 4(stst)" but “consecutive promotion(x4 sstt)”, to reduce the over-supply of keywords, and to allow more selective filtering. Comments welcome. (2021-02-26)

Spezielle ehrende Erwähnung von Preisrichter Boris Shorokhov, der in seinem Preisbericht schreibt:
"Für drei Umwandlungen schwarzer Bauern in Damen werden neun Züge benötigt. Bisher gelang dies nur mit zu vielen schwarzen Bauern, d.h. in illegaler Stellung. Der Autor dieser Aufgabe vermeidet solche Positionen, aber die erste Umwandlung in eine Dame ist retroanalytisch begründet, offensichtlich war 1. d1=D+ der letzte schwarze Zug. Natürlich ist das nicht dasselbe, aber nach meiner Meinung verdient die Findigkeit des Autors eine spezielle Auszeichnung." (2021-04-22)
James Malcom: This problem is mentioned on berlinthema.de on 159 of this document: http://www.berlinthema.de/AUSWAHL_PH.pdf (2022-01-31)
A.Buchanan: It would be cool if our keyword system distinguished cleanly between retro & forward promotions. However we have too much clutter in the current vocabulary to extend in this way right now, imho. (2022-01-31)

Die Stellung läßt sich nur durch d6xc5 entsperren, nachdem der wUW-Bd bis d5 zurückgezogen hat. Nur der wLd2 läßt sich zunächst befreien, er muß also auf d8 entwandeln. Nach dem dafür notwendigen Lf4-d2 Sd2-f3+ braucht Schwarz 5 Tempi, vier liefert der sBg2, den fünften der sBa2. Nachdem dafür notwendigen Db3-a3 ist allerdings die falsche Seite am Retrozug, e7-e8=S würde die Retrozugpflicht auf Schwarz abwälzen, versperrt aber dem wL den Weg nach d8, analog e5-e6 und e3-e4. e6-e7 bzw. e4-e5 und e3-e3 würden den Weg wieder freimachen, aber mit der falschen Seite am Retrozug. Nur e2-e4! verhndert beides.

Dreifache Retro-Intersection (e7,e5,e3), dreimal Retroopposition (e8,e6,e4), weißer Excelsior-Bauer e.

'phénix': "Trois positions de rétro-intersection pour le pé (é7, é5, é3).
Trois positions de rétro-opposition pour le pé (é8, é6, é4).
Cinq rétro-coups pour un excelsior du pé (promu en Cavalier), afin de changer la parité de la position, dont trois essais correspondant aux trois rétro-intersections.
Une idée nouvelle semble-t-il, et en tout cas extrèmement originale."
Yoav Ben-Zvi: Analysis in English (approved by the composer):
The release of the Western cage requires unpromotion of WBd2 on d8 (via f4-d6-e7) and retreat of the unpromoted pawn to d5 allowing retraction of BPd6xc5. When WBf4-d2 is retracted BN stands on f3 or f1 (ready to retract to d2 to replace the WB as a shield for the WK) and completion of the maneuver requires 5 tempo retractions by BPs including BPa3-a2. This means WQa3 and WRa4 need to stand on b3,a4 (not on a3 as this obstructs the retreat of BPa2). The position of the mobile pieces WQ,WR and BN implies, by the "Parity Argument", that prior to the retraction of WBf4-d2 White must retract an odd number of moves by a pawn unpromoted from WNe8. Standing on e6 or e4 the unpromoted pawn has played an even number of retractions while on e7, e5 or e3 it interferes with the retro-path of WBd2 to d8 so its only option is to retract to e2 using a double-step first move.
Parity Argument is the main theme of the problem combined with Retro-Opposition on a3 between BPa2 and WQb3/WRa4. (2017-11-27)

Wie erwünscht, provozierte diese Aufgabe eine Unmenge von Kommentaren, die ich aus Platzgründen nur teilweise und ggf. gekürzt wiedergeben kann:
“Ser-!# war 2009/10 das Thema bei Chessproblems.ca. Da gab es zahlreiche gelungene Aufgaben, aber keine, die eine Rochade enthält.” [Alfred Pfeiffer]
“Come-back zum Feld d2 nach Unterverwandlung. Fantastische Idee!” [HK]
“Eine interessante, mir noch nicht aufgefallene Forderung, die sofort zum Mitmachen anregt.” [KF]
“Hat mir viel Freude bereitet, ganz tolle Knobelei!!” [BL]
“Eine interessante Aufgabe, die man mit viel Überlegen vom Blatt lösen konnte.” [JB]
“Dass Weiß bei dieser Forderung im letzten Zug ins Schach ziehen darf, geht mir irgendwie gegen den Strich.” [BS]
Daniel Papack schrieb einen längeren Kommentar, in dem er die häufige Darstellung von Märchenschachelementen in Aufgaben kritisiert, die auch mit klassischen Forderungen bzw. Elementen komponierbar sind. Er gab zu obiger Aufgabe ein ähnliches Beispiel als ser-h# an. Grundsätzlich hat er natürlich Recht, auch mir stößt das häufig auf. Für dieses konkrete Beispiel würde ich dies aber nicht anwenden wollen, denn: “Wie so häufig, habe ich mein Problem zum Testen von Gustav gebaut. Ich wollte prüfen, ob die Rochade im Mattzug korrekt funktioniert. Dabei ist was Hübsches rausgekommen.” [Autor]

Der Autor hat einer Exzelsior-Aufgabe aus dem Jahr 1984 eine vollzügige Drohung beigegeben. Das ist eine objektive Verbesserung und poliert das Problem in geeigneter Form auf. Im Gegensatz zur logisch unterfütterten Aufspaltung des Doppelschritts (der aber schon in der früheren Version vorhanden war), erachte ich dies aber eher als Kosmetik denn für ein thematisch erforderliches Element. In dieser Form jetzt eine abgerundete Sache!

A rather... complicated "joke."
A.Buchanan: If one allows promotion to sB (and there seems no reason to disallow it since promotion to pawn, king and foreign units are allowed) then the problem is cooked. There is no universally agreed notion of how a pawn can move if it starts on the first rank. Does it get a double hop, and if so on which rank? But the problem is unsound in any case. (2022-02-10)
James Malcom: That is if, yes. But I don't think this problem ought to be left as is: a demonstration of the levels of absurdity and tomfoolery old rules used to allow. Promotion to a piece of another color and dummies were loopholes, yes, but promotion to a black pawn was never included, not even implicitly. All pawns are pieces, but not all pieces are pawns.

Scheint ein Selbstplagiat zu sein. Das Stück wurde in Problemas (SEPA), 07/2020, Heft 31, H1, Seite 935 als Original veröffentlicht.
Henrik Juel: C+ Euclide 1.01
This is an example of the retro theme of WCCT-11
The thematic square is b1, where Sb1 is not original, but promoted, and where Black promoted, only to have his promoted piece captured later
The fact that the promotions are both to knight is not required by the theme (2021-03-21)

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.
