What is a fork in classical chess middlegames?

How do I spot a hanging piece in a chess puzzle?

A hanging piece is a piece that is undefended or only loosely defended and can be won tactically. Scan the board for pieces that are attacked more times than they are protected, especially after a forcing move. Hanging pieces often decide puzzles in just a few moves.

Why are checks so important in chess puzzles?

Checks are powerful because they limit the opponent’s choices and often reveal tactical weaknesses. A well-timed check can force a king into a bad square, expose a pinned piece, or create a discovered attack. In many puzzles, the best move starts with a check for that reason.

What does pin mean in chess tactics?

A pin happens when a piece cannot move without exposing a more valuable piece behind it, usually the king or queen. Pins are common in opening and middlegame tactics because pieces are still coordinating and the king may be vulnerable. Once a pin is created, it can become the basis for winning material.
