Englund Gambit Complex Hartlaub Charlick Gambit Hanging Piece in Chess

In the Englund Gambit Complex (Hartlaub–Charlick Gambit), the “hanging piece” motif appears when a sacrificed pawn/initiative leaves a key unit en prise—often a minor piece or the queen-side defender—without immediate protection. The defining feature is that after the forcing sequence (typical Englund sacrifice ideas), the opponent can win material because the attacked piece cannot both defend itself and stop threats.
