Queens Pawn Game Accelerated London System Clearance Puzzle (Rated 1305): Clear the File — Trapped Piece

This puzzle is a classic middlegame example of clearance and trapped-piece tactics. White’s heavy pieces are coordinated to exploit the queen’s awkward placement and the lack of safe squares around it. The key idea is not a direct attack on the king, but a forcing sequence that removes key defenders and opens a file for the rooks. In classical chess, these winning combinations often arise when one piece becomes overloaded and another is left without escape squares.
