Learn How to Win Material: Tactical Fork
This middlegame puzzle comes from the Queen's Gambit Declined, where White has active pieces aimed at the black king and a loose defensive setup around the center. The key idea is to use a forcing attacking sequence that drags the king into the open and creates a fork on the next move. In positions like this, activity matters more than raw material: the bishop and knight work together to exploit king safety, weak squares, and hanging pieces.
