Learn How to Win Material: Tactical Skewer
This middlegame puzzle comes from the French Defense and shows how active rook play can turn a small edge into a decisive material gain. White’s king is safe, but the queenside pieces are vulnerable and one long-range piece is exposed to a skewer. The key idea is to use forcing moves to attack a defended piece and the piece behind it at the same time, creating a winning combination rather than a direct mating attack.
