Sicilian Defense Four Knights Variation Puzzle (Rated 932): Fork — Decisive Material Gain

This puzzle comes from the Sicilian Defense and shows how a forcing queen move can create a crushing tactical fork. The key idea is that the enemy king is exposed to check while an important piece is also under pressure, so the defender has to respond to the check first. That tempo often leaves the targeted piece hanging. In sharp classical chess positions, this kind of tactic can decide the game by winning material and simplifying into a clearly better endgame.
