1. h7! thr. (2. De5+! Kxe5 3. h8D+ Ke6 4. Dh6+! Ke5
5. Te7+ Le6#)
1. - Lb2
2. b7! Lxd4 → interim celar-up (3. - Ke5)

4. d5+(!) Ke5
5. Tf5+ Lxf5#
6. Ke7??/Kf7??

Exceptional quiet and zweckrein replacement of white queen against "stronger" white pawn. Thematic temptation,
full-length threat, including theme Phoenix, pleasant finale.
