Learn How to Win Material: Discovered Attack
This puzzle comes from the English Opening and shows a classic middlegame tactical refutation based on a discovered attack. White’s pieces are coordinated around the kingside and queenside at the same time, so one forcing move creates multiple threats. The key idea is that a checking capture can pull a defender away, opening lines for a bishop to attack a loose piece and a vulnerable rook-side target. In positions like this, tactical accuracy turns a small edge into decisive material gain.
