Jean Marc Loustau: Variations in the actual play:
1… Rd7 2 Qxd7#
1… Rb3! 2 Re8# changed (and not 2 Qd7??)
Diagonal/Orthogonal correspondence, with 2 phases showing white anticritical moves on the same square (f8) and 2 other phases showing Bristol in threat and 1 variation (also D/O correspondence between the 2 checking attempts with white self-interferences).
This main thematic content is enhanced by a strategically linked 5th phase (1 Qf3?), 3 changed mates, and a correction play in the real play.
The matrix is of course already known, but the way it is exploited is new. (2022-05-03)
