Learn How to Exploit a Pin: Crushing Defensive Move
This middlegame puzzle is about turning king safety and piece activity into a decisive tactical edge. White’s heavy pieces are coordinated against the enemy king, while Black’s material lead is undermined by loose coordination and a vulnerable queen-side setup. The key idea is to use a forcing defensive move that improves piece placement and creates a direct tactical threat. In positions like this, the best move often combines prophylaxis with an attack on a hanging piece.
