The wQ has to be activated, but 1. Qa6? (threat 2. Ncd2#), Qh3? (threat 2. Nfd2#) fail to 1.. Bxf3!, Bxc4! when the planned mates would leave e5 unguarded. In the solution, with a capturing key guarding e5 again and threat 2. Nd6#, the threat mates from the tries reappear after the same black moves that refuted them in the tries - which is the paradoxical Dombrovskis theme. The N-mates display the Somov theme ("Black opens a white line (f1-d3) so that another white line (d1-d3) can be closed on the mating move.") In this problem the solver may indeed consider the tries first before hitting on the key. FIDE Album.
