Queens Gambit Declined Normal Defense Skewer in Chess

A Queens Gambit Declined Normal Defense Skewer is a tactical motif in the QGD Normal Defense where one piece attacks another along a line and forces the target to move, revealing a stronger attack behind it. In practice, the defining feature is often a skewer created by a bishop or queen on a diagonal/file that lines up the opponent’s piece (commonly near the center or on the queenside) with a more valuable unit behind it. The result is usually material gain because the front piece cannot move without exposing the back piece to capture.
