Learn How to Trap a Piece: Decisive Material Gain
This puzzle comes from the French Defense Advance Variation and shows a classic middlegame pattern: a trapped piece becomes vulnerable because its escape squares are cut off. White’s attack is built around king safety, pressure on the kingside, and a tactical sequence that forces Black into a losing decision. The key idea is not a flashy checkmate, but a decisive winning combination that exploits a pinned pawn structure and a badly placed rook.
