Queens Pawn Game Discovered Attack Puzzle (Rated 936): Spot a Discovered Attack — Mate in 2

This middlegame puzzle is a classic example of a discovered attack turning into a forcing mating net. One piece’s movement opens a line for another attacker, and the exposed king has too few safe squares to survive the follow-up. The key idea is not just winning material, but using the opponent’s king safety weaknesses to create a direct checkmate threat. In positions like this, tactical refutation often comes from seeing how one capture or check changes the entire board.
