Sicilian Defense Wing Gambit Intermediate Puzzle (Rated 848): Win Material — Discovered Attack

This chess endgame puzzle shows how a single forcing idea can turn an equal-looking position into a decisive material win. The key motif is a discovered attack: one piece moves with tempo, uncovering a stronger line from a rook behind it. In practical classical chess, these tactics often appear when pieces are aligned on open files and an enemy piece is overloaded or pinned. Here, the tactic works because the opponent’s king and rook coordination cannot absorb the threat.
