Learn How to Exploit a Discovered Attack: Tactical Gain
This middlegame puzzle comes from the Queen's Gambit Declined, where White spots a tactical shot based on a discovered attack and kingside pressure. The key idea is that one piece can be sacrificed to open lines against the enemy king while also exposing a loose queen and overloaded defenders. In classical chess, these motifs often decide the game because they convert activity and king safety into direct material gain.
