Indian Defense Discovered Attack Puzzle (Rated 1002): Spot a Discovered Attack — Mate in 2

This middlegame puzzle is a classic example of a discovered attack turning into a forcing mating net. White’s active pieces coordinate against the black king, and the key idea is to use a forcing check that opens lines for the queen. The position also shows how king safety can outweigh material: even when one side is materially ahead, an exposed king can be vulnerable to a short tactical finish. Recognizing the hidden line behind the first check is the whole point.
