Der Autor heißt Gino F. v. Moellwitz. Das F. hinter Gino bezeichnet seinen zweiten Vornamen,
nämlich 'Forst'. Alle Stücke, die unter Nachnamen 'Forst' gespeichert sind, müssten demnach auf
v. Moellwitz umgearbeitet werden. Siehe dazu Anmerkungen zum 80. Geburtstag des v. Moellwitz von
Dr. W. Speckmann in der SCHWALBE Heft 71, Oktober 1981. (db)

Mario Richter: Interessant: Wenn ich eine PDB-Abfrage starte mit "A='Forst, Eugen'", erhalte ich nicht nur Probleme des Autors "Eugen Forst", sondern auch einige des Autors "Gino F. von Moellwitz" (z.B. P1393805).
Gibt es da ein undokumentiertes "hidden feature" in der PDB, das einen Link zwischen bürgerlichen Namen und Pseudonymen herstellt? (2021-09-18)

Mattwechselfleck
A.Buchanan: Actually sublime. Completely different motivation for the Flecks across the two twins. In a) the three thematic defences each capture a guard and cover a mating square for dual avoidance. In b) wQ itself selects a mating square to attack the unguarded square. The only tiny defect is that keys such as 1. Qh1? are impossible because they would solve both twins! Different starting squares for wQ can work in each case, but it's not worth doing it, because the slightness of the delta adds to the charm. Fun to spot why Bg2 can't start on h1. (2021-04-10)

Record holder for #2 pure Fleck theme: each threatened mate must be forced at least once, and there are no duals at all. The 13th variation seems to require #3 to show purely.

In dieser bauernlosen Aufgabe stehen Weiß einige Mehrfachdrohungen zur Verfügung. Welche ist die richtige - im Hinblick auf eine wichtige Verteidigungsressource?

Es wimmelt geradezu von möglichen Mattdrohungen und Verführungen. Deshalb also prüfen: Wie kann sich Schwarz verteidigen? Als entscheidend erweist sich eine Mehrfachdrohung.
