Kings Indian Attack Spassky Variation Puzzle (Rated 1041): Win a Trapped Piece — Tactical Refutation

This middlegame puzzle is a classic trapped piece tactic: one active bishop can step onto a powerful square, forcing a trade that wins material and leaves the opponent’s queen exposed. The position rewards accurate calculation rather than slow maneuvering. White’s queen is active, but Black’s piece activity and tactical pressure create a forcing sequence that turns the extra piece into a liability. In classical chess, these decisive material-gain patterns often come from a quiet-looking move that changes the whole evaluation.
