Learn How to Trap a Piece: Winning Material
This puzzle is about a trapped piece and a forcing sequence that turns a stable middlegame edge into a decisive material gain. White already has the better pawn structure, extra material, and more space, but the key idea is to use a pawn break to open lines and expose a piece that has no good squares. Once the defender is overloaded, the position simplifies in White’s favor and the trapped piece becomes impossible to save without losing material.
