Russian Game Puzzle (Rated 1084): Win a Fork — Decisive Advantage

This middlegame puzzle shows how a single tactical shot can turn a strong attacking position into a decisive advantage. White’s active knight and rook coordinate against Black’s king and loose pieces, creating a forcing sequence that wins material and leaves Black’s position collapsing. The key idea is not a direct mating attack, but a tactical refutation based on king safety, piece activity, and a hanging major piece that cannot be defended cleanly.
