Queens Gambit Declined Cambridge Springs Defense Discovered Attack in Chess

The Queens Gambit Declined Cambridge Springs Defense Discovered Attack is a tactical motif where White uses a move like c4 or an exchange on d5 to open a line, revealing an attack on a more distant target. In this QGD structure, the defining feature is the tension around the d5 pawn and the pin/discovery potential created by the queenside pieces and central pawns. The “discovered” part happens when one piece’s move (often a pawn break or capture) suddenly exposes an attack that was previously blocked.
