Learn How to Win Material: Discovered Attack
This middlegame puzzle is built around a discovered attack that also creates a forcing defensive move. One piece is already active on a strong diagonal, while the opponent’s king and heavy pieces are vulnerable to tactical pressure. The key idea is that a checking move can force the king into a specific square, allowing a rook to capture with tempo and keep the attack alive. It is a classic example of how activity and coordination can outweigh raw material in a sharp classical chess position.
