Modern Defense Neo Modern Defense Puzzle (Rated 1525): Trap a Piece — Decisive Material Gain

This middlegame puzzle shows a classic trapped piece idea: one side’s queen and rook coordination creates a tactical refutation against an undefended back-rank target. The position is not about slow maneuvering; it is about recognizing when a piece is overloaded and when a forcing sequence wins material immediately. In modern defense structures, active piece placement can quickly turn into a decisive advantage if the opponent’s king is still in the center and key defenders are loose.
