What is it?
A missed battery is when you could have lined up two of your pieces on the same line to concentrate pressure on an enemy weak point — often in front of their king — but didn’t seize the chance.
How it happens
The battery is built by doubling your rooks on an open file, or placing queen and bishop on a diagonal towards the enemy castle. You miss it by playing isolated moves instead of coordinating your heavy pieces on one target.
How to avoid it
When a file opens or a diagonal aims at the enemy king, think about stacking your pieces on it before your opponent. The front piece threatens a breakthrough, the second recaptures: often decisive.
The concept in the glossary
Battery
A battery in chess is a setup in which two pieces of the same color are aligned on the same line — a [file](/en/glossary/file), [rank](/en/glossary/rank), or [diagonal](/en/glossary/diagonal) — so that the rear piece reinforces and amplifies the power of the front piece. The most common forms are: two rooks stacked on an open file, a [rook](/en/glossary/rook) and a [queen](/en/glossary/queen) aligned on a file or rank (in either order), and a [bishop](/en/glossary/bishop) paired with a queen on a diagonal. Knights, which do not [move](/en/glossary/move) in straight lines, cannot be part of a battery. The more powerful piece is often placed behind the leading piece for support, but the order may vary depending on the tactic at hand. In practice, building a battery requires first opening or controlling the relevant line. A well-placed battery can simultaneously threaten multiple squares and force the opponent into passive defence.

Frequently asked
- Which battery is strongest?
- It depends on the target: queen and rook on an open file facing the king, or queen and bishop on the long diagonal, are the sharpest because they allow a sacrifice followed by recapture.
- How do I set up a battery?
- Open or take control of the line, place the support piece first (often a rook), then bring the front piece in front — ready to strike the weak point.
