Learn How to Win Material: Fork Tactic
This middlegame puzzle from the Nimzo-Indian Defense shows how a forcing check can create a fork-like tactical sequence and win material. White already has active pieces and pressure against Black’s queenside, while Black’s king is still uncastled and vulnerable. The key idea is to use tempo to expose loose pieces and force a defensive reply, then convert that initiative into a clean material gain. In classical chess, such tactics often arise when development and king safety outweigh static structure.
