Learn How to Win Material: Fork Tactic
This middlegame puzzle comes from the Vienna Game and shows a classic fork-based winning combination. White’s advanced knight looks active, but it is actually overextended and vulnerable to a tactical refutation. Black’s queen can create a forcing check that drives the king and opens the way to win the loose knight. The key idea is that active-looking pieces can become targets when they are not supported and when the king is still exposed.
