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

What is a zwischenzug in chess?

A zwischenzug, or intermezzo, is an unexpected forcing move played before an obvious recapture or response. Usually it is a check, capture, or threat that improves the outcome of the sequence.

How can a skewer win material in classical chess?

A skewer attacks a valuable piece first, forcing it to move and exposing a less valuable piece behind it. Checks are especially effective because the opponent must answer immediately, often allowing the attacker to win material afterward.

What is the best defensive move when my king is under attack?

How do I recognize a trapped piece in a chess puzzle?
