What is a discovered attack in chess?

A discovered attack happens when one piece moves away and reveals an attack from a piece behind it. It is especially powerful when the hidden piece attacks the king, queen, or another loose target. These tactics often win material because the opponent must respond to the newly revealed threat.

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

Look for aligned pieces on the same file, diagonal, or rank, especially when one of them can move with tempo. If your move creates a check or attacks an important piece, it may be a discovered attack. Also check whether the opponent’s queen or king is overloaded and unable to defend everything.

Why are pinned pieces important in tactical puzzles?

Pinned pieces have limited mobility, so they often cannot respond to threats or capture the attacking piece. That makes them ideal targets for discovered attacks and tactical refutations. When a pinned piece is also defending another key piece, the whole position can collapse quickly.

What should I calculate before playing a tactical move?

First, identify forcing replies: checks, captures, and threats. Then see whether your move opens an attack on the king or queen, and whether the opponent has any defensive resources. Good calculation often reveals that a quiet-looking move is actually the strongest tactical shot.
