Learn How to Win Material: Fork Tactic
This puzzle comes from the Nimzowitsch Defense and shows how a forcing queen move can create a tactical fork while the enemy king is still vulnerable in the center. The key idea is not a mating attack, but a decisive material win: the checking move pulls the king into a less flexible square and leaves a major piece hanging. In practical classical chess, these short combinations often decide the middlegame by converting activity into material.
