Learn How to Win Material: Trapped Piece
This puzzle comes from the Nimzo-Indian Defense, where Black uses active piece play to punish White’s loose king and awkward development. The key idea is a tactical queen invasion that creates immediate threats against the h1 rook and the kingside structure. In the opening, even a small lead in development can outweigh material, especially when one side’s pieces are passive and the king is still in the center. That is why this position is a classic example of a winning combination based on activity and a trapped piece.
