How do I spot a skewer in a middlegame?

Look for two valuable targets aligned on the same rank, file, diagonal, or move sequence. If attacking the front piece forces it away, the piece behind it may become vulnerable. Always check whether the skewer also reveals a discovered attack.

What is a discovered attack in chess?

A discovered attack occurs when one piece moves away and uncovers an attack by a rook, bishop, or queen. The moving piece may create a second threat, making the tactic especially powerful. Check lines behind knights and pawns before assuming they are safe.

How can I avoid a hanging piece in classical chess?

Before making a move, identify every attacker and defender of your pieces. Recalculate after the move, because moving one piece may open a file or diagonal against another. Knights deep in the opponent’s position deserve particular attention.

Why is material more important than space in a chess puzzle?

Space helps your pieces, but it does not compensate for losing material without sufficient activity. When a tactical opportunity wins a piece or creates a lasting advantage, it usually outweighs a temporary space advantage. Compare concrete gains with positional benefits.

What should I check before choosing a candidate move?

Use the forcing-move order: checks, captures, and direct threats. For each candidate, calculate the opponent’s strongest reply and look for tactical resources such as pins, skewers, forks, and discovered attacks. Only then compare quieter moves.
