Learn How to Win Material: Discovered Attack
This puzzle shows a classic discovered attack in the middlegame of the Queen's Gambit Declined. White’s knight is tied to a tactical role, and moving it creates a direct line for another piece to strike a loose target. The key idea is that one tactical move can simultaneously give check, expose a pinned piece, and force the opponent into a defensive response. In positions like this, activity and coordination matter more than static material balance.
