Queens Indian Defense Discovered Attack Beginner Puzzle (Rated 1237): Spot Discovered Attack — Mate in 2

This middlegame puzzle is a classic discovered attack pattern that ends in a forced mate in 2. White’s advanced pawn creates a direct tactical threat by opening a line for the queen while also exposing the enemy king’s weaknesses. The key idea is that one move can serve two purposes: it checks the king and uncovers a stronger attack on a critical square near the king. In classical chess, these hidden line-opening tactics often decide the game immediately.
