The logic is not as simple as one would think (which makes the problem all the more interesting). The Breton adverse condition allows White to remove any black P when capturing Pe5. So White sets up a threat by removing a guarding bP … no, that is true only for the solution! Rf5-e5 actually sets up two threats (Sf5#, Rxe4#), and the bP removals on b7 and f7 serve as dual-avoidance effects (Sushkov-theme style). The removal of Pf3 in the solution rules out both threats by dual-avoidance effects, but lets in a new threat by removal of a guard (so this is a form a threat correction, too).

The appearance of all three thematic mates in every phase works quite seamlessly. I’m especially impressed with how Sf5# and Rxe4# are produced in the solution.
