GrüNfeld Defense Skewer in Chess

A Grünfeld Defense Skewer is a tactical motif where the Grünfeld player uses a line piece (often the queen or rook) to force a skewer: one piece is hit “in front,” and a more valuable piece behind it is attacked along the same line. In Grünfeld structures, this commonly appears after moves like ...c5 and ...Qa5+ (or related queen placements) that align the queen with a target on the a5–e1 diagonal or a file. The defining feature is the immediate alignment that turns a normal Grünfeld setup into a direct, forcing attack.
