Queens Pawn Game London System Hanging Piece Chess Puzzles

In the queens pawn game London system, White usually develops the bishop to f4 early and builds a solid setup with d4, Nf3, and e3. A hanging piece in this structure is a piece that is undefended or only weakly defended, often appearing after Black challenges the center or misplaces a knight or bishop. The key idea is that the London’s calm development can suddenly punish a loose piece with a tactical shot.
