French Defense Classical Variation Skewer in Chess

In the French Defense Classical Variation, a “skewer” is a tactical motif where one piece is forced to move (or is pinned) so that a more valuable piece behind it is attacked along the same line. In this opening, the defining feature is the Classical structure and piece placement that often align a long-range piece (commonly the queen or bishop) with a target on a file or diagonal. The skewer typically arises after the position opens enough for a line to form, turning a seemingly solid setup into a direct tactical threat.
