Learn How to Win Material: Trapped Piece
This middlegame puzzle comes from the Philidor Defense and shows how a single loose piece can decide the game. White’s active pieces create pressure, but Black can turn the tables by exploiting an undefended bishop and the coordination around c4 and a3. The key idea is not a flashy attack, but a clean tactical sequence that wins material by forcing exchanges and exposing a trapped piece. It is a classic example of how piece activity and hanging-piece tactics can outweigh general positional concerns.
