Queens Gambit Accepted Gunsberg Defense Discovered Attack in Chess

In the queens gambit accepted gunsberg defense, Black accepts the pawn and develops in a way that can leave a piece line vulnerable. A “discovered attack” happens when one move (often a pawn or piece shift) reveals an attack on a more valuable target behind it. The defining feature is a line-opening move that suddenly attacks the king, queen, or a major piece while the Gunsberg setup is still present.
