Das Themaspiel hat logischen Charakter; der schwarze Turm/Läufer wird spezifisch auf ein Feld gelenkt, auf dem er geschlagen wird, um die andere schwarze Figur (durch Circe-Transport) zu verstellen (Treffpunkt reziprok, Orthogonal-Diagonal-Echo). Doch hat Schwarz in den anderen Verteidigungen Turm/Läufer schlägt Turm die Ausrede, daß er den weißen Turm als Block auf das erwünschte Mattfeld transportiert. Diese Verteidigung wird dadurch ausgeschaltet, daß Schwarz zuvor selbst das erwünschte Wiedergeburtsfeld betreten muß. Leider passiert dieser Inhalt erst nach dem zurechtstellenden Schlüssel.

Gefordert waren orthodoxe Zweizüger mit einer Verführung, die durch eine Drohung und zweu Widerlegungen hat. In der Lösung sollen diese Widerlegungen als Verteidigungen auftreten. Nach der einen Verteidigung folgt der Verführungs- Schlüüsel als Mattzug (Wladimirow-Effekt),
während bei der anderen Verteidigung die Verführugs-
Drohung durchschlägt. (Dombrowskis-Effekt)
Eine der beiden Einträge zeigt das Thema ohne eine Batterie in der Lösung. Saubere, interessante und elegante Aufgabe. (Preisrchter P. Einat) (2018-11-9)

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: Linienfreilegungen mit vertauschten Farben.
Die Mattfelder f2 und g5 sind von s. Bauern gedeckt, die aber der w. Läufer bequem aus dem Weg räumen könnte. Probe:
1. Lxg3+? - Kxe3 2. Lf4+ - Ke4, 3. Sf2+? - Lxf2! Oder :
1. Lxh6+ - Kxe5, 2. Lf4+ - Ke4, 3. Sg5+? - Txg5!
Auch S. verschafft sich neue Deckungen für die Mattfelder: 1. La2! (droht 2. Lg5+ - Kxe5, 3. Df4+ - Ke6, 4. Bc5#)
1 . - Tc5 ( verstellt die Linie a7-f2 und erlaubt):
2. Lxg3+- Kxe3,
3. Lf4+ - Ke4,
4. Sf2#.
Umgekehrt ist nach :
1. .... - Lc5, die Turmlinie in Richtung g5 unterbrochen,
2. Lxh6 - Kxe5,
3. Lf4+ - Ke4,
4. Sg5#.
