Philidor Defense Lopez Countergambit Fork Puzzle (Rated 858): Win a Fork — Decisive Material Gain

This middlegame puzzle shows how a single tactical shot can turn a strong position into a winning material advantage. The key idea is a forcing queen move that creates a check while also attacking an important piece, leaving the opponent with very limited defensive options. In classical chess, these combinations often arise when one side’s king is slightly exposed and a loose piece sits near the action, making a fork or capture with tempo especially powerful.
