Hauptplan:
1.Sc5+? …bxc5+, aber 1. …Kc3!
Also muss der weiße Springer das Feld b3 räumen, damit der weiße Th3 dort seinen Platz einnehmen kann. Aber wie soll das von statten gehen?

Lösung:
1.Dc8+! …Ka7
2.Dc6! …Kb8
3.Td8+! [AZE] …Ka7
4.Te8! [4.Te~?] …Ka6
5.Sc5+! …Ka7
6.Sd7! [4.S~?] …Ka6
7.Te3! …Ka7
8.Teb3 [Blockwechsel] …Ka6
9.Dc8+ …Ka7
10.Db8+ …Ka6
Und nun kann der Hauptplan endlich erfolgreich durchgeführt werden:
11.Sc5+! …bxc5# - Mustermatt

(MD1775)

Inhalt:
Neudeutsch-logisches Selbstmatt. Der Hauptplan scheitert daran, dass der weiße König über b3 flüchten kann. Nachdem der weiße Springer umgruppiert wurde und der weiße Td3 stattdessen das Feld b3 blockt, kann der Hauptplan erfolgreich durchgeführt werden. Außerdem AZE und zweimal weiße Auswahl (im vierten und sechsten Zuge). Mustermatt.
