Learn How to Deflect the Defender: Mate in 3
This middlegame puzzle is a classic example of deflection: one defender is lured away from a critical square, and the king’s position collapses under a forcing sequence.

The key idea is to use a forcing check that drags the defender off its post, opening a path for a decisive follow-up and a long-range mating net.
