Kings Indian Defense Semi Classical Variation Puzzle (Rated 1378): Win Material — Crushing Middlegame Tactics

This puzzle shows a classic middlegame tactical idea: use a forcing capture to drag a defender away from a key square, then exploit the resulting loose piece and open line. Black’s active pieces are coordinated, while White’s queenside structure contains a vulnerable target that can be hit immediately. The position rewards calculation over slow maneuvering, because the best continuation converts activity into a decisive material gain rather than a speculative attack.
