Yuri Bilokin: the idea is not new P1005163 (2022-08-06)
Jean Marc Loustau: ***
The matrix and the mates are indeed the same; but in this problem (P1100532) there is one more significant feature which is, in fact the main idea (which is not on the P1005163):
The 2 white thematic pieces can already play on the mate square in the diagram position: thus we have a kind of "peri-white Grimwhaw" (a 3 moves manoeuvre to reach the mate square which was already reachable).
Of course I did no know the P1005163 when I have composed this one... I would say "fortunately", because if I had knew it, probably I would not have worked on this matrix: my final result, in my opinion, is interesting enough with its new feature to deserve the publication. (2022-08-14)

A.Buchanan: Legality/illegality is orthogonal to fairy. Let us say here it is "not fairy". (2023-07-09)
Adrian Storisteanu: Add, say, "circe" under the diagram, and all is pretty cool. Even cooler, "chess960". (2023-07-10)
