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

What is a tactical refutation in classical chess?

A tactical refutation is a forcing sequence that proves an opponent's plan or move is inaccurate. Instead of slowly improving, you use checks, captures, or threats to win material or gain a decisive position. In classical chess, these ideas often come from piece activity and coordination.

How do pins help create winning combinations?

A pin restricts a piece from moving because doing so would expose a more valuable piece behind it. That limitation can make the pinned piece a target for forks, discovered attacks, or overloads. Strong players use pins to reduce the defender's options before striking.
