Every page is also served as markdown at its URL plus .md. A loose piece is a piece that no friendly piece or pawn protects. Loose pieces are the raw material of many tactics. A loose piece is a piece that no friendly piece or pawn protects, which makes it a target even when nothing attacks it yet and gives the opponent a chance for a double attack. Loose pieces are the raw material of many [tactics](https://georgelichess.com/glossary/tactic.md). The word describes the state of a piece, not a threat against it: it stands on a [square](https://georgelichess.com/glossary/square.md) that none of your other units covers. Today it may be perfectly safe, but one forcing move can turn it into a victim. The reason loose pieces matter is that a [double attack](https://georgelichess.com/glossary/double-attack.md) needs only one undefended target to work. A [knight](https://georgelichess.com/glossary/knight.md) check, a queen check or a pawn push that attacks two things at once wins material the moment one of them is unprotected. If both targets were defended, the fork would often cost the attacker a piece instead. The habit to build is a safety scan before and after each move. List your [undefended pieces](https://georgelichess.com/glossary/hanging-piece.md) and ask which enemy move would hit one of them with tempo. Then do the same for your opponent, since a loose rook or [bishop](https://georgelichess.com/glossary/bishop.md) on the other side is the signal to look for a check or a fork. You can fix a loose piece by guarding it, trading it, or moving it to a covered square. Pieces that have advanced deep into enemy territory, far from their own defenders, are frequent offenders. Nothing attacking a piece right now does not make it safe. Safety depends on the next forcing move too. ## Example position The rook on b7 has no defender. Nd6+ checks the king on e8 and attacks b7 at the same time, so after the king moves, Nxb7 wins the rook. Position (FEN): `4k3/1r3p2/8/8/4N3/8/8/6K1 w - - 0 1` Also worth reading is [Trapped piece](https://georgelichess.com/glossary/trapped-piece.md). A trapped piece cannot reach safety: every square it might retreat to is covered, blocked or ruinous, so once it is attacked the owner will lose it for little or nothing. Knowing "Loose piece" helps most once you can spot it in a real game.
