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

Look for a piece that cannot move because a more valuable piece, usually the king or queen, stands behind it. An absolute pin involves the king and cannot legally be broken. In a middlegame, combine the pin with checks or attacks on another loose piece.

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

How can I win material when my opponent is ahead?

Tarrasch Defense Puzzle (Rated 1431): Pin — Win Material

This crushing middlegame puzzle highlights how a pin can turn king safety into a decisive material gain. A valuable defender is tied to the king, while active attacking pieces create a skewer and multiple overloaded threats. Even though Black has extra material, White’s initiative is more important: the exposed king and restricted pieces make the position tactically unstable. The key idea is to exploit the absolute pin before the opponent can untangle or save the attacked pieces.
