Learn How to Win Material: Tactical Refutation
This Ruy Lopez puzzle shows a classic opening tactic where king safety and piece activity outweigh raw material. White has overextended a bishop deep in enemy territory, but the position is unstable because that piece is not adequately supported and the black king can respond directly. The key idea is to recognize when a seemingly active attacking piece is actually hanging and can be eliminated, turning the attack into a winning material sequence for the defender.
