Learn How to Deflect: Decisive Material Gain
This middlegame puzzle is a classic example of deflection: one forcing move drags the king into an awkward square, then the follow-up wins material by exploiting the exposed king and loose pieces. In the Ruy Lopez Berlin Defense structure, Black’s queen and bishop coordinate against White’s king safety, while White’s pieces are overloaded and underdeveloped. The key idea is not a direct mate, but a tactical refutation that converts pressure into a decisive material gain.
