Gunter Jordan: Erstaunlich, dass solch ein Riesenproblem im Preisbericht nicht erwähnt wurde, nicht einmal im Nachspann des Berichtes, wo i. d. R. die Aufgaben stehen, die knapp gescheitert wind. Es muss für den Autor eine späte Genugtuung gewesen sein, sein Stück im FIDE-Album wiederzufinden. (2022-01-05)

A.Buchanan: Hi Gunter thanks for your scholarship. The specified syntax for PDB is to separate phases by commas. If something only occurs in 1 phase I guess it would be e.g. "L,". It is not a good idea to have multiple occurrences of the same keyword within a problem, because that makes counting & quality-checking more difficult, and is fiendishly difficult to track. Thanks for your understanding. If you have different opinions, please express them here, in German or English. (2022-08-01)

Gunter Jordan: Lieber Yuri, wie mir die Autoren mitteilten, kannten sie die von dir angegebene Stellung (und noch weitere Versionen), doch entschieden sie sich bewusst für ihre Diagrammposition, weil darin Weiß nicht nur drei Anfangszüge hat, wovon sogar zwei lösen, sondern eine größere Auswahl in einer viel freieren Stellung.

because White has lost his right to castle, as Andrew will explain, I hope... (2023-07-29)
A.Buchanan: White has not necessarily lost the right to castle, but if he can castle then the 50M rule triggers before the mate can be executed. It is pretty complicated, sorry. (2023-07-29)
A.Buchanan: We don't do mottoes much these days. Mrs Baird was a big fan. On page 301 of the July 1916 Chess Amateur P.H. Williams wrote:
"I think it was Mrs Baird who did more to search Shakespeare for accidental (or deliberate) reference to chess, since all her retractors had Shakespearean mottoes, and her knowledge of the Avonian bard was obviously extensive. Her example was followed by other composers of retractors, who considered such positions would be incomplete without some reference to the poet."
But there are other great playwrights, and Asteroid 5696 was named after one such, whose bitter quotation accurately states this problem's theme. (2023-07-31)
Henrik Juel: The citation is by danish philosopher Søren Kierkegaard (1813-1855) and means something like
Oh yes, to be right, to be right; it does not help much that you are right, when you have no power. (2023-07-31)
Henrik Juel: Asteroid 5696 is named Ibsen after the norwegian playwright Henrik Ibsen (1828-1906), who must have borrowed the citation from Søren Kierkegaard (2023-07-31)
A.Buchanan: Thanks for this Henrik - I resolved the question here: https://philosophy.stackexchange.com/questions/101229/did-ibsen-originate-this-statement
Beyond the castling try, the other innovation here is in the solution beginning 1...Se6. Castling convention and 50M I think are trying to combine by Retro Strategy (being optimistic about 50M rights like we are with castling, rather than pessimistic like we are with ep). (2023-08-04)

19.592 (Jordan) Stünde der wSf4 auf e3, ginge 1.Sb2 Ke5 2.Sbc4+ Kf4 3.Sd5 matt. Nur, wie kommt der wSf4 nach e3? – Gar nicht! Nach einem eigenartigen Verfolgungsgalopp tauschen die wSS ihre Funktionen! 1.Sb2! (2.Sc4 matt) Ke5 2.Sfd3+ Kd6! 3.Sc4+ Kd5 4.Se3+ Kd6 5.Sb2! Ke5 6.Sbc4+ Kf4 7.Sd5 matt (4 P.). „Zweispringerspiel. Leider kein Mustermatt, was bei –wBf2 +sBg3 jedoch der Schlusspunkt wäre (gleiche Lösung C+)“ (VZ). „Die Reiterei bestimmt das Geschehen, wobei man genau hinschauen muss, um sich nicht zu vergaloppieren“ (HH). „Neckischer Tanz der wSS, witzig“ (BK).
Gunter Jordan: Der Kommentar von VZ ist falsch. Nach –wBf2, +sBg3 existiert genauso wenig ein Mustermatt, wie nach der Lösung der Diagrammposition. In dieser Matrix gibt es kein MM, da beide Springer im Mattbild e3 decken. (2022-06-13)

"wTb2/wTd4 können auf b8/d8 nicht selbst mattsetzen; erst ihr Ersetzen durch den jeweils anderen wT auf ihren Diagramm-Feldern ermöglicht diese Matts. Grund für diese Paradoxie: Das Opfer von sTb5/sTd5 ist der einzige Weg, diese Matt-Verhinderer auszuschalten." [Autor]
