Learn How to Win Material: Queen's Gambit Declined
This middlegame puzzle comes from the Queen's Gambit Declined, Exchange Variation, where king safety and piece activity matter more than simple material count. White appears to have a healthy position, but Black’s pieces are aimed at the kingside and one loose piece creates a tactical target. The key idea is to notice when a seemingly active attacking piece is actually overextended and can be removed by force, turning the attack into a winning material sequence.
