What is an x-ray attack in chess?

An x-ray attack is pressure directed through one piece toward a more valuable piece, king, or key square behind it. If the front piece moves, is pinned, or becomes tactically vulnerable, the hidden target can be attacked or won.

How do I spot a pin in a middlegame?

Trace lines from each rook, bishop, and queen toward enemy pieces. A pin exists when moving the front piece would expose a more valuable target, especially the king in an absolute pin or a queen in a relative pin.

What is the difference between a skewer and a pin?

In a pin, the valuable piece is behind the less valuable front piece and cannot safely move. In a skewer, the valuable piece is attacked first and must move, allowing the attacker to win the piece behind it.

How can I avoid tactical refutations in chess?

Before committing to an active move, check whether your pieces are defended and whether any line attack connects them to your king or queen. Calculate the opponent's forcing captures and recaptures, then look for overloaded or pinned defenders.

What should I calculate first in a chess puzzle?

Start with forcing moves: checks, captures, and direct threats. After finding a candidate, identify every legal reply, especially captures that remove a defender or create a fork, skewer, or decisive material gain.
