Anderssen's Opening Skewer in Chess

Anderssen's Opening Skewer is a tactical motif where a piece attacks along a line and forces the opponent’s piece to move, revealing a more valuable target behind it. In the Anderssen’s Opening family, it often arises after early development and central pressure, when a bishop or rook gains an open file/diagonal and lines up the enemy piece with the king. The defining feature is the “skewer” alignment: the attacked piece is between the attacker and the king.
