(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.

Gunter Jordan: 1. .. Dxh8 verhindert auch die Drohung, denn 2.Tf5+ Kd6 3.e8L+? Dxf8! oder 3. .. Ke6 4.Ld7+ Kxf7!

A.Buchanan: I completely agree Joost, but it clearly means something to Gunter who uses it from time to time, and I would like to understand him (2023-08-07)
