Philidor Defense Lopez Countergambit Beginner Puzzle (Rated 1379): Use a Discovered Attack — Tactical Refutation

This puzzle comes from the Philidor Defense and shows a classic middlegame tactical refutation. White’s attack is built around king safety: a well-placed knight creates pressure, and the opponent’s last move leaves key pieces and pawns vulnerable. The idea is not a flashy mating net, but a forcing sequence that wins material by opening lines and exposing an undefended piece. In classical chess, these moments often decide the game before the endgame begins.
