Here is the top line from the Chest solution tree:

 Bc7 Qxc8 gxf7+ Kh8 Be5   Qc5   Bb2    Nc7  Ba1    a4   Bb2    a3   Ba1    a2
Bb2    a1=B Bxa1   Nb5  Ke6+   Nc3  Bxc3+  Qe5+ Bxe5#

After 5.Ba1 black suffers zugzwang.
The complete solution tree is a bit long, but the above line should show
the basic idea.
