King's Indian Attack Puzzle (Rated 1319): Win Material — Tactical Refutation
This puzzle shows a classic middlegame tactical refutation in the King’s Indian Attack. White’s advanced bishop and active pieces look impressive, but the position contains a loose piece and a vulnerable queen-side structure that can be exploited immediately. The key idea is to challenge the overextended piece, force a recapture, and then use the queen to win material. It is a clean example of how activity can be punished when one piece is left hanging.
