How do I spot a pin tactic in a middlegame chess puzzle?

Look for a piece that cannot move because it would expose a more valuable piece behind it, usually the king or queen. Pins become especially strong when the pinned piece is also a key defender of another weakness. In middlegame puzzles, active rooks and queens often turn a pin into a winning tactical sequence.

Why are checks so important in tactical refutations?

In many winning combinations, a check improves piece coordination and exposes pinned or overloaded defenders. That is why forcing moves are usually the first thing to examine in a puzzle.
