Learn How to Win Material: Skewer Tactic
This middlegame puzzle comes from the Queen's Gambit Declined and shows how a tactical shot can turn a stable-looking position into a decisive material win. Black’s active pieces coordinate against White’s loose bishop and queen, creating a forcing sequence that wins material by exploiting tactical geometry. The key idea is not a mating attack, but a clean advantage-capturing combination based on piece activity, a skewer, and a vulnerable defender.
