(Beine). Dargestellte Themen: Miniatur-Oneliner, neutrale AUW mit Umwandlungswechsel aller drei nBB, im 2. und 3. Zug reziprok vertauscht, Mustermatt. EB: da ich kein Löseprogramm für Ultraschachzwang habe, mußte ich wohl oder über selbst ran. Klar war eigentlich von vornherein, daß nur eine neutrale Batterie mit einer Front-Dame erfolgreich sein konnte. Den genauen Ablauf zu finden, war dann doch recht mühsam. Die b)-Lösung ist dann mehr oder weniger nur ein Anhängsel, um die AUW zu komplettieren.

(A. Beine). Umwandlungs- und Mattwechsel. Etwas störend empfinde ich, dass zufällig noch eine zusätzliche sUmwandlung auftritt, was wie ein ungewollter Pinselstrich im Bild wirkt (EB). Mattbildbastelei, USZ verhindert hier nur Nebenlösungen, gefällt mir nicht (KHS). Zu beachten sind noch die beiden gegenläufigen wK-Rundläufe in den ersten drei Zügen.
