The Discovered Attack: A Surprise Weapon

What is it?
An attack that is revealed when one piece moves out of the way of another. This creates two threats at once: one from the piece that moved, and one from the piece that was uncovered.
How to Identify
Look for a "battery" formation where a long-range piece (queen, rook, bishop) is aimed at a target but blocked by one of your own, less valuable pieces.
Why is it Important?
The double threat is often impossible to parry. The opponent must respond to one threat, allowing you to follow through with the other.

How to Set Up a Devastating Discovery

From Good to Great: Pro-Level Tips

Make the Discovery Deadly

The most powerful discoveries are ones where the moving piece also makes a major threat, like capturing a piece or threatening checkmate. The more threats you create, the harder it is for your opponent to defend.

The Discovered Check is King

A discovered check is the most powerful form of this tactic. When the uncovered piece checks the king, the opponent *must* deal with the check, giving the piece that moved a free turn to wreak havoc anywhere on the board.

A Move That Made History: The "Evergreen Game", Anderssen vs. Dufresne, 1852

The Evergreen Game is filled with brilliant tactics, and while it features many themes, the idea of discovered attacks is central. Moves like 19. Rad1! prepare a battery on the d-file. The final combination starting with 20. Rxe7+! unleashes a series of discovered checks and threats that lead to a forced mate. It's a beautiful illustration of how multiple discoveries can be chained together in a single, breathtaking combination.

Frequently Asked Questions

What is a discovered attack in chess?

A discovered attack is a chess tactic where moving one piece uncovers an attack from a long-range piece behind it. This creates two simultaneous threats that are often difficult for an opponent to handle.

What is a "battery" in chess?

A battery is a formation of two or more pieces that work together on the same line or diagonal to create a discovered attack. A common example is placing a knight in front of a rook or queen.

What makes a discovered check so dangerous?

A discovered check is extremely dangerous because the opponent is legally obligated to respond to the check from the uncovered piece. This gives the piece that moved a "free" turn to capture material or create another threat, completely unopposed.
