VL: Reprints: (5) The Problemist, p.255, 11/2013 (in my article "Completely Unavoidable Mate"). Røpke is the correct name. (2017-12-3)
Henrik Juel: Røpke constructed this as a sort of joke problem, when Dansk Skakproblem Klub (The Danish Chess Problem Society) held a one day excursion for members (all men) with their spouses
The motto was Alt for damerne (Everything for the ladies) and the problem was posed for the spouses
ö is the German equivalent of the the Danish ø
The Genre should be n#, not Fairies, I think (2017-12-3)

VL: Only one castling is legal. Therefore, due to Art.16 (3) of the Codex, this diagram, as is, represents a retro-problem (PRA) with NO SOLUTION if w.O-O is legal. The genre and the soundness can be recovered by a shift of a wP. (2017-11-25)
VL: Continuation. In reality, the second part of Art.16(3) formally preserves the soundness of problems like this one (without any changes in their positions): namely, in the framework of Retro-Strategy (RS), which justifies the choice of appropriate castling as a part of the solution! However, such a subtle retro-enrichment lies, apparently, beyond the original intention. (2017-12-1)

Fast Berolina: All pawns are Berolina pawns; they are also "fast" which means they may make a double-step non-capturing move at any time, rather than merely on their first move. The last move to the the diagram could have been 12. - g7-e5 or 12. - d7xXd5.

PR Andrej Frolkin in seinem Entscheid für 2012: "Hier paßt der gewaltige Wust an Märchenregeln nicht zum relativ moderaten Inhalt und rechtfertigt nicht die Geduldsprobe für Löser und Prüfer, die nur sehr beschränkt mit Logik an die Lösung heran gehen können. Redakteure sollten solche Stücke vielleicht nur bei 'C+' veröffentlichen oder außerhalb des Löserwettbewerbs präsentieren.

VL: Only one castling is legal. Therefore, due to Art.16 (3) of the Codex, this diagram, as is, represents a retro-problem
(PRA). However it has 3 solutions if O-O is legal but only 2 solutions otherwise. The genre and the soundness can be recovered by an additional technical wP. (2017-11-26)

Das 100 Lire-Thema!! (Autor)
Kommentare: Ja, mit Torus...man sollte meinen, dass es da noch viel gefährlicher wird, oder? (HG).
Sehr sparsam realisiert. Hier kam ein schönes Problem dabei heraus und nicht wie bei vielen anderen Versuchen wurde die Bedingung genutzt, um das Ganze nur mal darzustellen (AB).
100 Dollar im (Ring-)Zylinder. Intelligente Begründung für die bei diesem Thema schwierige sS-UW (TS).
100 Dollar auf anderem Brett (MN).
Da haben wir ja das 100 Dollar-Ding (HM).
Noch nicht ganz, siehe die Autoranmerkung. Ich habe mit dem Autor beim letzten mpk-Treff gesprochen. Es ist noch nicht sicher, welche Währung als nächste dran ist. Vielleicht Escudos? \eb
Olli Heimo: Why torus? Isn't horizontal cylinder enough? Moving everything two squares to the right (or six squares to the left) makes full use of the torus-board. PS. Are there any freeware programs to check cylinder-board problems. (2017-12-11)

In bereits 9 Halbzügen kann die geforderte Stellung erspielt werden, wobei die Bedingung Annanschach gut genutzt wird. Überraschenderweise wird die weiße Dame nicht auf ihrem Ursprungsfeld geschlagen. Ein schöner Abschluss dieser Beweispartie ist die Annanschach-spezifische Rückversetzung des weißen Bauern c4 auf die Grundreihe.

Henrik Juel: To show that 4.5 moves is the length of the shortest proof game, one must also check shorter lengths, I think
Popeye uses 3 minutes to verify that no proof game in 4.0 exists (2017-12-11)

VL: Only one castling is legal. Therefore, due to Art.16 (3) of the Codex, this diagram, as is, represents a retro-problem
(PRA). a) is sound with one solution consisting of two partial ones.
b) has 3 solutions if O-O-O is legal but only 2 solutions otherwise. The genre, and the soundness (of b)) can be recovered by an additional technical wP. (2017-11-26)

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)

Yoav Ben-Zvi: The first 2 moves of Try and Solution are by wR forcing decoy of bR to a position obstructing each of Black’s bishops allowing wR to play its third move without fear of being captured. If a bB is subsequently decoyed then wR exploits this by switching sides (left to right in the Try and right to left in the Solution). The Solution presents a third decoy of the bR (second obstruction of bBe1) followed by a fourth (bR abandons row 3) which wR exploits by again reversing sides playing a Switchback to f4 (1.R-f4 and 6.R-f4).

In terms of logical structure the first 2 moves of the Try constitute a “main-plan” played in the Solution as moves 4,5 after a preliminary maneuver (“fore-plan”) that neutralizes the refutation (by decoy of bBd1).

Minichess: Reglerne er de samme som på et normalt bræt, dog er bondeforvandling kun tilladt til en briktype, hvis denne ikke findes på brættet allerede og er af samme farve. F.eks. er sort forvandling til en Løber kun tilladt, hvis sort ikke har en Løber på brættet (derimod må hvid gerne have en Løber).

Bauernumwandlungen sind nur erlaubt in Figuren (gleicher Farbe), die nicht mehr auf dem Brett stehen!
Henrik Juel: Black is stalemate in the final position, because 10.c1=DTLS,e1=DTLS are illegal in Minichess, as Black already has DTLS on the board (2017-11-28)

49. Thematurnier von "problem"
Konstruktionsaufgabe von Dr. W. Dittmann (problem 10/1967, S. 11):
A) Es ist eine Stellung zu konstruieren, partiemöglich und ohne Umwandlungssteine, in der Weiß vor seinem 1. Zug möglichst viele, vor seinem 2. Zug möglichst wenige verschiedene Züge hat. Der auszuführende 1. weiße und 1. schwarze Zug kann vom Konstrukteur im Hilfsspielverfahren bestimmt werden. Von der Zügeanzahl vor dem 1. weißen Zug ist die Zügezahl vor dem 2. weißen Zug abzuziehen. Die so ermittelte Zahl soll möglichst hoch sein. Der wK soll weder vor dem 1. noch vor dem 2. weißen Zug im Schach stehen.
