Learn How to Win Material: Accelerated London System
This middlegame puzzle comes from the Accelerated London System and shows how a small tactical idea can swing the evaluation sharply. White’s advanced knight creates direct threats against the enemy queen and rook, but the real lesson is that active pieces can also be overextended. When a piece jumps deep into the position, always check whether it is protected, whether it can be captured, and whether the opponent has a forcing reply that wins material or neutralizes the attack.
