Polish Opening Symmetrical Variation Puzzle (Rated 1471): Win a Fork — Decisive Material Gain

This middlegame puzzle is built around a classic tactical fork: one advanced pawn creates a double attack on two valuable targets at once. White’s pieces are active, Black’s king is still in the center, and the position contains loose coordination that makes a tactical refutation possible. The key idea is not a slow maneuver but a forcing sequence that wins material by exploiting the enemy queen and knight being vulnerable to the same pawn thrust.
