James Mason (Black) Puzzle: Use a Skewer — Tactics

A skewer is a line tactic in which a valuable piece is attacked while a less valuable target sits behind it. Here, White’s active queen creates exactly that geometry against Black’s unprotected queen and the knight behind it. The immediate capture wins the most valuable loose piece and transforms a material deficit into a decisive advantage. It is a clean example of why undefended pieces and aligned targets demand urgent tactical attention.
