Dutch Defense Nimzo Dutch Variation Puzzle (Rated 913): Win Material — Hanging Piece Tactic

This middlegame puzzle is a classic hanging piece tactic: one side has a loose piece on a powerful square, but the real point is that the position is tactically overloaded. When a defender is removed, the opponent’s coordination collapses and a major piece can become vulnerable on an open file. The winning idea is not slow maneuvering; it is a forcing sequence that converts activity into decisive material gain.
