Sicilian Defense Mengarini Variation Puzzle (Rated 1133): Win Material — Pin Tactic

This middlegame puzzle is a classic example of a pin creating a decisive material win. One piece is tied to the king, which makes a seemingly active queen vulnerable to a tactical shot. The key idea is that the pinned queen cannot freely respond without exposing a more valuable target, so the defender becomes overloaded. In positions like this, the strongest move is often a forcing one that turns the pin into a direct win of material.
