Nimzowitsch Defense Declined Variation Skewer in Chess

In the Nimzowitsch Defense (Declined Variation), a “skewer” is a tactical motif where one piece attacks an enemy piece and forces it to move, revealing or exposing a more valuable target behind it. In this family, the defining feature is often that Black’s setup in the center/queenside creates a line (commonly along a file, rank, or diagonal) that can be used to drive a white piece away from its protection. The result is a skewer that wins material or at least forces a favorable exchange.
