Sicilian Defense Velimirovic Attack Puzzle (Rated 1675): Win Material — Trapped Piece Tactics

This middlegame puzzle is a classic example of a trapped piece tactic where active piece placement creates a decisive material gain. White has extra material and space, but Black can use a forcing bishop move to overload the queen and exploit the loose coordination on the queenside. The key idea is not a mating attack, but a tactical refutation that wins material by creating a fork-like sequence and forcing simplification on favorable terms.
