Learn How to Deflect the Rook: Mate in 3
This middlegame puzzle is a classic example of deflection combined with a pin and a long-range mating net. The key idea is to force a defender away from its critical square so the final mating blow becomes unavoidable. In positions like this, the attacking side often uses checks to drag the king into a vulnerable line while another piece controls escape squares. The result is a forced sequence that looks simple only after you see the geometry.
