Learn How to Deflection: Mate in 3
This middlegame puzzle comes from the French Defense and shows how a forcing tactical sequence can punish loose coordination around the king and back rank. White’s pieces are active, and the key idea is to use a forcing check to drag the king into a worse square, then exploit the overloaded defenders around the d-file. The position is a classic example of deflection combined with a discovered attack, where one tactical shot creates a direct path to mate.
