Definition:
Three trys by different white pions fail on three different escapes of the black king from the corner.
In the solution, two completely different matt images: one on the edge, which ends with pattern matt, and one surprisingly in the middle of the board.
Kindergarten problem.
Rex-solus.
Miniature.
A.Buchanan: Two of the tries are bogus in that the sK move is forced. It’s like counting a random queen check as a try if Black’s only legal reply is to capture the queen (2020-11-06)

Dreimal Rundlauf der weißen Dame in der Miniatur.

Man könnte in der Ausgangsstellung auch den wLf8 nach h6 stellen, dann wäre die Aufgabe auch C+. Dann hätte man einen Nimm-und-Gib-Schlüssel, aber keine Verführung.
