Blackmar Diemer Gambit Declined Weinsbach Defense Skewer in Chess

The Blackmar Diemer Gambit Declined Weinsbach Defense Skewer is a tactical motif arising after the Blackmar-Diemer Gambit is declined and the Weinsbach Defense structure is reached. A skewer occurs when a piece attacks an enemy piece that is lined up behind it, forcing the front target to move and exposing the back target to capture. In this line, the defining feature is the skewer threat created by the attacker’s alignment against the opponent’s more valuable piece (often the king or a major piece) after the gambit is declined.
