Sicilian Defense Open Beginner Puzzle (Rated 851): Win a Fork — Decisive Material Gain

This puzzle shows a classic middlegame fork in the Sicilian Defense, where one active knight creates a forcing tactical sequence against multiple loose pieces. The key idea is not a mating attack, but a decisive material gain: a single check can also attack the queen and a trapped bishop, turning activity into concrete profit. In classical chess, these tactics often appear when development and piece coordination are uneven.
