Learn How to Win Material: Pin Tactic
This middlegame puzzle shows a classic pin-based tactic in the Nimzo-Larsen Attack, Modern Variation. One piece is tied to a more valuable target, so a seemingly active position can collapse into a decisive material gain. The key idea is that the defender is overloaded: if it moves or is exchanged, the pinned piece becomes vulnerable and the position opens up. In practical play, these patterns often decide the game without any direct king attack.
