Learn How to Win with a Pin: Tactical Advantage
This middlegame puzzle is about using a forcing check to drag the enemy king and pieces into awkward coordination. Black’s active bishops create a direct tactical threat against the white king while also exploiting loose pieces and weak squares. The key idea is not just the check itself, but the follow-up: once the defender is forced into a passive square, another piece can jump in with tempo and increase the pressure. It is a classic example of tactical refutation in a sharp master vs master setting.
