What is a discovered attack in chess?

A discovered attack happens when a piece moves away from a line, revealing an attack by a rook, bishop, or queen behind it. The moving piece may create a second threat, making the tactic especially powerful.

How do I spot a discovered attack in a middlegame?

Look for a piece standing between a long-range attacker and an enemy target. Check whether that piece can move with check, capture, or another threat while opening the line behind it.

How does a bishop fork win material?

A bishop fork attacks two valuable targets at the same time, often a queen and rook. The opponent usually cannot save both pieces, so the fork produces a decisive material swing.

What should I calculate before playing a tactical move?

Start with forcing moves: checks, captures, and direct threats. Then examine the opponent’s checks, captures, and counterattacks before confirming that your intended combination is safe.

What is the difference between a pin and a discovered attack?

A pin restricts a piece because moving it would expose a more valuable piece behind it. A discovered attack is created when a piece moves and uncovers an attack from another piece; one move can involve both motifs.

Alberic O'kelly De Galway Puzzles Puzzle (Rated 2100): Attack — Win Material

The key idea combines a bishop fork, a discovered attack, and forcing checks to exploit Black’s exposed king and poor piece coordination. Accurate calculation turns a dangerous position into a decisive material gain.
