Learn How to Win Material: Hanging Piece
This Grunfeld Defense puzzle shows how a single hanging piece can collapse a position even in the opening. White appears active, with development and space, but one loose knight creates a tactical target that Black can exploit immediately. The key idea is that opening advantages are only real if your pieces are defended and your king is safe. When a piece is undefended, tactical motifs like forks, pins, and discovered attacks often override static factors.
