Attraction Advanced Puzzle (Rated 2199): Pin — Winning Tactic

A discovered attack becomes powerful when a pinned piece can move with purpose. Here, the knight appears restricted because Black’s queen pins it to the rook behind it, but that pin also creates a tactical relationship: moving the knight uncovers the rook’s attack on the queen. The key is to prepare the geometry with a quiet move, then use an intermezzo check to gain time before collecting material. This is a classic winning combination built on clearance and piece coordination.
