Learn How to Win Material: Crushing Fork
This middlegame puzzle from the Nimzo-Larsen Attack shows how a forcing check can expose a loose king and create a decisive tactical sequence. Black’s queen and rook coordinate aggressively against White’s king, while White’s pieces are awkwardly placed and one bishop is especially vulnerable. The key idea is to use king safety and piece activity together: when the enemy king is exposed, a forcing move can win material by dragging the king into a worse square and opening a direct capture on a hanging piece.
