Vienna Game Trapped Piece Intermediate Puzzle (Rated 1222): Clear the Rook — Trapped Piece

This puzzle is a classic clearance and trapped piece pattern in the middlegame. The key idea is to remove a defender or blocker so a heavy piece can invade and win material. Here, the position features strong pressure on the king and a vulnerable back-rank-style setup around the enemy rook and queen. The winning idea is not a direct attack on the king, but a forcing sequence that exploits alignment, overload, and the lack of safe squares.
