"11 sDD-Züge - fantastisch" (TC) "Weltrekord" (BG) "nicht allzu schwer, aber raffiniert ausgeklügelt" (AG) "Schwierigkeit ist ja kein Wertkriterium und umso reizvoller ist dann das Suchen nach den (echt weiblichen!) verschlungenen Wegen, auf denen die D sich ihren Zeitgewinn erschleicht" (HHS) "eine respektable Leistung" (MS) 3,5/III/9L.

"nochmal fantastisch" (TC) "Weltrekord" (BG) "hier sind es sogar 13 Züge, die der sL benötigt um eine Tempo zu verlieren, wobei das weiße Spiel mit äußerster Präzision angelegt sein muß, um Zugumstellungen zu vermeiden" (MS) "wenn die Bändigung der D auch schwerer zu bewerkstelligen ist und entsprechend mehr Respekt verdient, so hat diese L-Darstellung doch mehr Finessen, eine interessanteres Spiel beider Parteien mit mehr Alternativen. Und dann gefällt mir 'optisch' die Db8, die sekundenlang suggeriert, sie könne den sS geschlagen haben und die zur Unzeit dorthin ziehen muß und alle Hoffnung auf Tempoverlustmanöver von sD und sT zunichte macht" (HHS) "Zwei Superstücke mit 11 D- bzw. 13 L-Tempozügen!" (CP) "Wäre es nicht redaktionell klüger gewesen, die beiden Stück nicht nebeneinander zu stellen?" (HHS) Die Überlegung brauchte ich aufgrund meiner mageren Retrovorräte nicht anzustellen ... 4/III-IV/8=L.

Gerd Wilts: Sensationell, dass dieser erste vierfache Pronkin gekocht wurde! Hoffentlich bleibt der zweite, exakt thematische (P1067975) korrekt. Man kann die vierfachen Pronkins übrigens leicht mit folgender Suche finden: K='Pronkin:[DTLSdtls][DTLSdtls][DTLSdtls][DTLSdtls]' (2009-04-20)

paul: The length record for a capture-free PG is now 40.5 moves by Th. le Gleuher (Phenix50/1997) (2019-07-16)
Mario Richter: The problem Paul was referring to is P0006623. So far it has resisted all my and rawbats' attempts to cook it, and I think that chances are high that it is indeed correct ... (2019-07-17)

Reto: There are in fact solutions in exactly 25.0 moves and Stelvio finds those. So the above comment is incorrect. (2023-06-12)

A very attractive game with long trajectories by the thematical Rooks. A problem without apparent promoted man on the diagram had to be among the Prizes!!"

Richter: Hans Gruber
Drei en passant-Schläge, keiner davon am Ende. Das Pronkin-Thema ist
eine feine Zugabe zu diesem Problem mit faszinierender
Stafettenstrategie. Der Autor betont das Fesselungsmatt; auch wenn
das kein sonderlich aufregender Punkt ist, ist das Mattbild doch für
eine Beweispartie ungewöhnlich elegant und damit eine feine Zugabe.
paul: The first 16 moves checked by Jacobi. (2019-11-05)
paul: And also tested the last 17 moves. (2019-11-05)
Henrik Juel: [Pc2] finishes its series of moves with 2.c5, so after 10... b6?, 11.cxb6 is illegal, because wPc5 is 'used'
10... b5+ 11.cxb6ep is legal, because the check cannot be answered by a 'fresh' man
Similar motivations for the black ep captures (2019-11-05)

paul: Last move of bR? (2015-03-04)
Henrik Juel: I had the same question, Paul.
One interpretation is that the game has proceeded normally, and only after Txd8+ does the circe condition kick in.
Another view (which I do not subscribe to) is that legality is inconsequential in problems with fairy conditions (2015-03-04)
Erich Bartel: Das kann jeder halten wie er will.
Ich halte bei Aufgaben mit Märchenelementen an meiner
Auffassung fest:
"Forderung ab Diagramm"
Die Legalitätsfrage ist m.E. nur dann sinnvoll, wenn sie
zum Inhalt der Aufgabe gehört. (2015-03-04)
Olli Heimo: This discussion has occured decades ago. Are there any legal positions with stipulation "Platszwächselcirce". We must assume that that fairy condinition begins with the diagram position unless the stipulation explicitely contains retroplay. About the legality of positions then I strongly suggest that if the position is illegal in normal chess, it should be legal with the given fairy condition. Olli. (2015-03-05)
