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

What is a decisive material gain in classical chess?

A decisive material gain means a tactical sequence that wins enough material to give one side a clearly better position.

Why are checks so important in tactical chess puzzles?

How can I improve at advantage fork puzzles?

Train yourself to scan for loose pieces, exposed kings, and forcing moves before considering quiet moves.
