"Da stimmt wieder etwas nicht: Die sZüge an sich sind eindeutig, nur ihre Folge läßt Umstellungen zu. Und die weißen? Nun ja, die o.a. S-Auswahl ist nicht das einzig Mögliche: auch auf c2 kann sich der wT opfern und der wS auf b1 und natürlich kann man 22. Lg2 ziehen und hat dann 0,5 Züge gespart!" (HHS) und darüberhinaus, gibt es auch BP, bei denen der Tg3 (statt Te3) UW-Figur ist. Also Nebenlösung (zum dritten!). Eine Korrekturversion kommt in der aktuellen Urdruckserie, so daß die Autorlösung zunächst zurückgehalten wird. 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.

"Sehr geschickt gebaut, obwohl man die Wiederholung der letzten vier Züge bedauern kann" (DB) "Zwei tolle Lösungen - mit jedem S einmal" (CP) "Ein reizender, allerdings leicht zu durchschauender Einfall! Leider ist eine gewisse Eintönigkeit nicht zu übersehen und der Sg hat keinen perfekt vollkommenen Rundlauf" (HHS) "Ein außerordentlicher/meisterlicher Fund" (GJ/FCh). "Bei aller Analogie mußte man doch noch exakt verfahren, um die SS-Rundreisen glücklich zu beenden!" (MS). Peter Wong reklamiert einen Vorgänger: PW, The Games and Puzzles Journal 1988/89: Weiß = PAS (16); Schwarz: Kd6, Ta8, Lc8, Lf6, Sb8, BBa7,b7,c7,d7,f,g7,h7 (12) KBP in 8 Zügen mit den Lösungen 1.

Dann verweist PW noch auf die Nr. 140 in 'Shortest Proof Games', die eine ähnliche Idee zeigt und nach der Ansicht von PW viel besser ist als 8131 und die oben zitierte Aufgabe. 3,3/II/14L.!
