Learn How to Win Material: Trapped Piece
This puzzle comes from a Queen's Pawn Game middlegame where one active piece has stepped too far and can be punished by tactical pressure. The key idea is a trapped piece: when a piece is overloaded, pinned, or forced into a bad square, a forcing move can win material by removing its support. Here, the position is not about a mating attack, but about converting activity into a decisive material gain through accurate calculation and simplification.
