Sally: Gut gelungener Verstellungsrömer.
1. Ld3! (droht 2. Ba8S),
1. - Le2/Lf2,
2. Sg8/Sf7 - Lb4/Ld4,
3. Lxe4#.
Hier ist es jedoch wichtig; die Verteidigungszüge vor dem
Schlüssel genauer anzusehen, ob nicht etwa Satzspiele zum thematischen Inhalt gehören. Hier geht nach :
1. .. Le1/Lf2 in vertauschter Reihenfolge 2. Sf7/Sg8 .
Und erst die Kenntnis der Wechselthematik bringt den vollen Genuss der Aufgabe. Hier wird im Satz und spiel der s. Läufer h4, so gelenkt, dass im einen Fall Tc1, in der Lösung hingegen Ta4 verstellt wird. dies wird durch Verlagerung des Mattfeldes von e6 nach er erreicht.

Sally: Hier möchte der Autor, dass der Löser zwei Satzspielen Beachtung schenkt, bevor er die Lösung sucht :
1. - De6, 2. f4+ (A) exf4, 3. Th5;
1. - Dxf7,2. Se4+ (B) fxe4, 3. Dg1.
Durch 1. Da5! mit der Drohung :
2. Dd8+ - Lf6, 3. Dxf6#; oder 3. Th5#.
läßt sich die schwarze Dame tatsächlich nach e6 oder f7 locken
aber anstelle der Satzmatts kommt es jetzt zu ganz neuen Matts unter Nutzung der Habfesselung.
1. - De6 , 2. Se4+(B) fxe4, 3. f4#.
1. - Dxf7, 2. f4+ (A) exf4, 3. Se4#.
Die zweiten Zügen werden im Vergleich zum Satz reziprok vertauscht. Dafür kommen die zweiten Züge des Satzes in der Lösung als Mattzüge. Auch nicht von schlechten Eltern!
Einziger Einwand: Wie soll ein Löser die Satzspiele entdecken, wenn es auf das starke 1. - Lxh6 kein Satzmatt gibt. (2017-7-31)
