Learn How to Win Material: Trapped Piece
This middlegame puzzle comes from the Polish Opening and shows how a tactical idea can turn a small edge into decisive material gain. White’s queen activity and bishop pressure create a vulnerable back rank of pieces, while Black’s heavy pieces are awkwardly placed. The key motif is a trapped piece: once the defender is forced away or overloaded, a major piece can be won cleanly. This is a classic example of tactical refutation rather than a mating attack.
