Giuoco Piano Puzzle (Rated 1392): Fork — Winning Endgame
This chess endgame demonstrates how forcing play can overcome a material deficit. Black has an extra pawn and active queen, but the queen is tied to a tactical alignment involving a vulnerable minor piece and pawn. White’s queen can exploit checks to displace the king, gain superior activity, and then win material. The key idea is a skewer: attack the king first, forcing it to move, and then collect the less valuable piece or pawn behind it.
