Modern Defense Three Pawns Attack Hanging Piece in Chess

In the Modern Defense Three Pawns Attack, Black often builds pressure with a pawn wedge that restricts White’s pieces and opens lines for tactics. The “hanging piece” part means a key White piece (commonly a central or pinned piece) becomes undefended or overworked, so it can be captured with tempo. A defining feature is the pawn structure and piece placement that let Black attack while White’s defenders are tied down.
