French Defense Trapped Piece Puzzle (Rated 956): Trap a Piece — Crushing Middlegame Puzzle

This puzzle is a classic trapped piece idea in the middlegame, where active coordination matters more than raw material. Black’s pieces work together to restrict White’s queen-side and central defenders, turning a normal-looking position into a decisive tactical bind. The key is that one piece becomes overloaded and then loses its best squares, allowing Black to win material with tempo. In classical chess, these are the positions where quiet pressure becomes a forcing sequence.
