Learn How to Win Material: Tactical Refutation
This puzzle comes from the King's Indian Defense and shows a classic opening tactic where one active piece becomes overextended and can be won by a pawn. The key idea is tactical refutation: when an attacking piece is left on a vulnerable square, the defender can often capture it and force a favorable sequence. Here, king safety and piece coordination matter more than long-term strategy, because the position is already tactically unstable and White can turn the attack into a decisive material edge.
