How do I spot a discovered attack in a chess puzzle?

Look for a move that moves one piece out of the way and reveals an attack from a stronger piece behind it. Checks, captures, and threats that open a line are the most common triggers. If the opponent’s king or queen is lined up with one of your pieces, a discovered attack may be available.

What is the main idea in a Grob Opening tactical puzzle?

How do I recognize a collinear tactic in classical chess?

What is a tactical refutation in chess?
