Learn How to Trap a Piece: Scandinavian Defense
This middlegame puzzle from the Scandinavian Defense shows how a loose queen and overloaded defender can turn a normal-looking position into a tactical win. White’s pieces are active, but the key idea is that one piece is trapped and the back rank of the queen-side becomes vulnerable. When a piece is forced onto a bad square, tactical motifs like skewer, x-ray attack, and removal of the defender often decide the game quickly.
