Trapped Knight Puzzle (Rated 1139): Win Material — Trapped Piece

This middlegame puzzle is about recognizing a trapped piece and converting it into a decisive material gain. White’s attacking pieces are coordinated around the enemy king, and the key idea is that one active capture can force a sequence where the defender’s heavy piece becomes overloaded. In practical chess, these positions often look like a direct attack, but the real point is tactical refutation: win material first, then simplify into a favorable ending.
