Learn How to Win Material: Tactical Refutation
This middlegame puzzle is a classic example of tactical refutation: one side has active pieces, but a loose defender and exposed king-side structure make the position collapse under accurate play. The key idea is to notice when a defended-looking piece is actually overloaded or pinned by the geometry of the board. Once the defender is removed, the remaining pieces can fall quickly, turning a seemingly normal position into a winning material sequence.
