Inhalt:
Meerane-Thema, Fünfte Form (Sauberer Reziprokwechsel-Meeraner): In einem Hilfsmatt mit zwei Lösungen führt Weiß den Schlüssel aus. Der Mattzug von Lösung I. wird zum Schlüsselzug von Lösung II. Der Schlüssel aus Lösung I. wird zum Mattzug in Lösung II.
Themafiguren: weißer König und weißer Bauer.
Hier findet die Thematik auf einem einzigen Themafeld statt (e8).
Zweimal Mustermatt.
Dieses Mal gibt es die Besonderheit, dass Weiß mit einer Bauernumwandlung arbeitet.
