How do I spot a pin in a middlegame?

Look for a piece that cannot move because something more valuable stands behind it, especially a king or queen. Trace the attacking line and check whether the pinned piece is also overloaded or vulnerable to capture.

What is the difference between a pin and a skewer in chess?

A pin restricts a lower-value piece because moving would expose a more valuable piece behind it. A skewer attacks the valuable piece first, forcing it to move and exposing the lower-value piece behind it.

How can I win material with a tactical refutation?

First identify the opponent’s immediate threat, then search for forcing captures that remove its main attacker. Check whether the enemy piece is trapped, undefended, or tied to another target by a pin or skewer.

From's Gambit Puzzle (Rated 943): Spot a Pin — Win Material

This middlegame puzzle highlights how a pin can transform a seemingly dangerous attack into a decisive material gain. White’s king is exposed, while several pieces are restricted by absolute and relative pins. The key idea is to recognize that an active enemy rook is vulnerable when it becomes aligned with another valuable piece. By exploiting this relationship, White can remove the most dangerous attacker and emerge with a significant material advantage.
