Confinement of King
How is BK confined now?
• Q, g2B, Kt define limits of BK movement: b4, b5, b6.

Which W piece can cover all 3 in one move?
• Q, by moving to a5.

How can a5 be guarded by some other piece?
• Bd2 (c1B has no effect presently)

Therefore,
1. Bd2...Kb6 (forced)
2. Qa5#

Note: the g2B & c1B could have been on h1 & h6, respectively.
