How do I spot a fork in a middlegame chess puzzle?

What is an exposed king in classical chess?

An exposed king is one with weak pawn cover, limited escape squares, or pieces that cannot defend it well.

Even when material is down, active pieces can create decisive counterplay against an unsafe king.

Why are knight forks so strong in the middlegame?

Knight forks are strong because knights attack in an unusual pattern and are hard to block. In the middlegame, they often work best when the opponent’s king and a major piece are aligned on vulnerable squares. A well-placed knight can create a forcing sequence that wins material or breaks the king’s position.
