Learn How to Win with a Fork: Tactical Refutation
This puzzle shows a classic opening tactic where one active knight creates immediate threats against the king and a major piece. In the Queen's Gambit Declined, small imbalances in development and king safety can turn into a decisive material win when a piece is left undefended. The key idea is not a long attack, but a forcing tactical refutation that exploits loose coordination and an exposed king in the center.
