Deflection Beginner Puzzle (Rated 1170): Exploit Exposed King — Mate in 3

This middlegame puzzle is a classic exposed king tactic: once the king’s shelter is weakened, forcing checks can override material concerns. The key idea is to use direct threats to drive the king onto a vulnerable square, then coordinate queen and bishop pressure to create a mating net. Even when one side is materially behind, active pieces and open lines can turn the position into a decisive tactical refutation.
