Sally: Umwandlung in sD, Liniensperre und vedoppelung der Türme
mit verändeter Reihenfolge.
S. 218 Ungarische S. Pr. Anthologie ( Bakcsi). (2010-06-21)
Erich Bartel: Hier wird der Vorwurf unnötigerweise auf 4 Züge aufgebläht. Zudem
ist in dieser Aufgabe kein kritischer Zug vorhanden,denn das kritsche
Feld g5 wird nur geräumt, nicht überschritten. Des weiteren ist der
Zug 1.h2 vollkommen irrelevant und überflüssig, da er mit dem Thema
nichts zu tun hat.Vielleicht war dies alles seinerzeit ein Grund,
dieser Aufgabe einen 2.Preis (?!)zu geben. (\eb)
vergleiche P1112056 (2010-08-01)
Viktoras Paliulionis: The problem shows a rare theme - Brunner-Zepler doubling. Rh5-f5 is an anti-critical move there. Additionally, there is Klasinc wR-wR. (2021-02-11)

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.

Thomas Brand wrote: "By the way, the position is also correct with sTd1 and wLc1 still present. Here, however, I completely agree with the author that this is one of the rare cases where the position with additional (even non-thematic) captures is preferable, since it hides the issue even better: why should the rook not have come via a1?"
Henrik Juel: White castles (to let wD out), 'uncastles' (to let sT in), and 'castles' again (to reach diagram) (2022-06-11)
Henrik Juel: Thanks for correcting the diagram, James (2022-06-12)
James Malcom: Ti's was Olaf, not me. I merely corrected the comma in the stipulation, which is something PDB needs sorted out--commas v. periods in BP/KBP problems. Consensus seems to learn towards periods, but many past entries contain commas. (2022-06-13)
A.Buchanan: You're welcome, Henrik. I didn't have the FEN, so edited the original diagram position manually - not the best procedure, but there was a solution to check against. Normally FEN to pieces is automated by a spreadsheet.
Continental European usage is comma rather than period, see: https://brilliantmaps.com/decimals/ (For readability of large numbers, the opposite convention is used: e.g. 1.234.567 vs 1,234,567. So combining them it would be 1,234,567.89 vs 1.234.567,89! See https://www.grammar-monster.com/lessons/commas_with_numbers.htm)
At some future point we can maybe have full internationalization of stipulations, but in the meantime, if I input e.g. a German or French problem, I respect their usage.
If I had to pick one, it would be comma, because period is used to indicate multiple solutions for helpmates e.g. 2.1... This matters because one often wants to search the stipulation as a string.
On the subject of the helpmate code: for various coherent reasons, I prefer no semicolons, ",5" over "0." and ellipsis after the first repeating "1.". It would be good to get consensus on this before implementing it. (2022-06-13)

Diagonalmarsch des schwarzen Königs von Ecke zu Ecke, in Miniaturform.
Diese Idee ist natürlich nicht neu, aber laut PDB sind mehrere Merkmale neu, nämlich:
Der weiße König von g2 muss weit weg (g5) von seinem Zielfeld gehen (f2), mit doppeltem aufeinanderfolgendem Switchback, die weiße Batterie feuert ZWEIMAL und in GEGENSEITIGE Richtungen, Klasinc wK/wB (f3), Tempo vom weißen Bauer.
Sowohl der weiße Inder als auch der schwarze Durbar wurden bisher nur EINMAL gezeigt, beide in P0501643, veröffentlicht in Probleemblad.
Das Schlagen der weißen Dame im Schlüsselzug wurde zweimal gezeigt, in P0501414 und in P1364909, letzteres auch in Probleemblad - Sie sehen, dass Probleemblad bereits eine gewisse Tradition in diesem Thema hat, was für uns der letzte Grund war unser Stück nur Ihnen anzubieten! Schließlich gibt es in der PDB drei Miniaturen zu diesem Thema, P0522184, P1005185 und P1364529.
Inder, Durbar und Miniatur sind zwar nicht neu, aber all das zusammen in ein und demselben Stück ist auch neu.

Kniest und Maslar mit dem umgewandelten Turm, Bauer(Turm)-Rundlauf von d7 nach d7, Klasinc (weißer Bauer / schwarzer König) in b).“ (Autoren) BK war „verblüfft, dass es keine Nebenlösung mit der weißen Dame“ gab. JB entdeckte das folgende Detail: „In a): Der erwandelte weiße Läufer räumt das Mattfeld für den schwarzen König, die schwarze Dame blockt. In b): Der erwandelte weiße Turm räumt das Mattfeld für den schwarzen König, die schwarze Dame ist Schlagopfer.“ Insgesamt gibt es hier „eine Fülle von strategischen Themen, wie z. B. schwarze Opfer, konsekutiver Umnow, Klasinc, Kniest, Koschakin-Thema, Maslar, Platzwechsel von weißem Turm und schwarzem König, Umwandlung in Turm und Läufer bei Weiß, Rückkehr des weißen Turms, ein Mustermatt. Der hohe Aufwand an schwarzen Steinen hat sich hier gelohnt. Schwierig und schön.“ (KHS) Dazu sehen wir noch einen „Rundlauf des weißen Läufers in a).“ (TZ) „Ein großartiger Hit in Sachen Hilfsmattmehrzüger.“ (JA)
