Learn How to Win Material: Discovered Attack
This puzzle comes from the Bird Opening, specifically a From's Gambit structure where tactical alertness matters more than slow development. Black has a clear forcing idea based on a discovered attack: a pawn move opens a line for the rook while also creating immediate threats against White's king-side pieces. The position is a classic example of how one active move can turn space, piece activity, and king safety into a decisive material edge in the opening.
