Bishop's Opening Boi Variation Puzzle (Rated 1019): Win Material — Tactical Refutation

This middlegame puzzle is a classic tactical refutation where activity beats material balance. White has extra material, but the king shelter is loose and key pieces are overloaded. Black’s best continuation uses a forcing check to drag the king into a vulnerable square, then a fork to win major material. The position is a strong example of how a single active knight can transform a slightly worse static position into a decisive advantage through forcing moves and piece coordination.
