Boris Spassky's talents are underappreciated. I came across a position of his that I found truly deep. Even after seeing the solution, I was bewildered why it works.

 

Can you solve?

Blokh Combinational Motives: Diagram 727, Difficulty 8, White to Move 

 

 

Why does this work?
 
On first instincts, after 1. Qh7+ Kf8 White would like to follow up with Nce6. However, this square is guarded 4 times.
 
The idea behind 1. Bd3 is to remove a defender of e6
 
If 1. Bd3 Bxd3 2. Qh7+ Kf8 3. Nce6+ (now that e6 is not defended by the Bishop) fe 4. de. The f-file is open and the Bishop is pinned the Queen such that Rxd3 followed by Rf3+ is deadly
 
If 1. Bd3 Qxc5 2. Bxf5 gf. The f7 square is the target and White coordinates with tempo after 3. Qh7+ Kf8 4. Qh5 and Qxf7 can't be stopped
 
If 1. Bd3 Qxc5 2. Bxf5 Nxd5 3. Qh7+ Kf8 4. Be6! taking advantage of a royal fork at e6 and pressure at f7/g8
