cxd4 Puzzle (Rated 1500): Pin — Win Material
A pinned piece can appear protected, but its limited mobility often creates a tactical target. In this middlegame position, Black exploits the coordination of the opposing pieces and the pressure on an advanced knight. The key idea is to attack the pinned or overloaded defender with precise timing, forcing an exchange that leaves Black with a decisive material advantage. This is a winning combination based on piece activity, tactical pressure, and the vulnerability of a defender tied to another responsibility.
