Italian Game Two Knights Defense Fork Puzzle (Rated 837): Win Material — Discovered Check

This classical chess middlegame shows how a forcing check can expose a loose queen and turn active piece placement into a decisive material gain. The key idea is a discovered check: one piece moves with tempo, revealing an attack from another piece behind it. In this kind of position, the side to move must respond to the check first, and that often creates a tactical sequence where a hanging piece or overloaded defender becomes impossible to save.
