Learn How to Win Material: Tactical Refutation
This middlegame puzzle comes from the King’s Indian Defense and shows how a seemingly active attacking move can backfire when the king’s shelter is already weakened. White’s queen is placed aggressively, but Black has resources that exploit the exposed king-side structure and the loose coordination of the attacking pieces. The key idea is tactical refutation: when a piece is overextended, forcing exchanges can turn an attack into a winning material sequence.
