Philidor Defense Steinitz Variation Puzzle (Rated 1497): Win a Fork — Decisive Material Gain

This opening puzzle shows a classic tactical refutation in the Philidor Defense: White uses active queen play to exploit an exposed black knight and the loose coordination around Black’s king. The key idea is not a flashy attack, but a forcing sequence that wins material by creating a fork and leaving the knight with no safe retreat. In the opening, even a small lead in development and king safety can outweigh a pawn deficit when the opponent’s pieces are overextended.
