Learn How to Win Material: Fork Tactic
This middlegame puzzle comes from the Semi-Slav Defense and shows how a forcing queen move can create a decisive material gain. The key idea is to exploit a pinned piece and the exposed king at the same time, turning a tactical threat into a fork-like win on the queenside. Even when the position looks balanced materially, active pieces and king safety can make one side vulnerable to a sharp tactical refutation.
