Philidor Defense Intermediate Puzzle (Rated 1154): Win a Kingside Attack — Tactical Refutation

This puzzle shows how a kingside attack can turn into a decisive tactical refutation when the enemy king is slightly exposed and key defenders are overloaded. White’s active rook and bishop create pressure, while the black queen is tied to important defensive duties. The winning idea uses a forcing sacrifice to open lines near the king and expose a hidden tactical resource. It is a classic middlegame pattern where activity and king safety outweigh simple material count.
