Learn How to Win Material: Tactical Refutation
This middlegame puzzle comes from the Sicilian Defense, Alapin Variation, where active queen play and loose pieces create a tactical refutation. The key idea is to notice when a seemingly normal move actually wins material because the opponent’s king is exposed and a defender is overloaded. Here, the position rewards calculation over general principles: a forcing check opens the way to a major material gain, turning a stable-looking board into a decisive advantage.
