Bishop's Opening Skewer in Chess

A Bishop's Opening Skewer is a tactical motif where a bishop on an active diagonal attacks one piece and forces it to move, revealing an attack on a more valuable piece behind it. In many Bishop’s Opening lines, this often starts with early bishop development (commonly Bb5 or Bc4) that creates a long diagonal toward the opponent’s king-side or center. The defining feature is the bishop’s line-up: front target pinned by the threat to the rear piece, producing a “skewer” rather than a simple pin.
