A pawn up is no comfort if the game ends two moves later. A poisoned pawn is a pawn that can be captured, but whose capture lets the opponent punish the greedy player with a tactic that costs more than the pawn is worth. The pawn looks free, and that is exactly the trap. It may be undefended or lightly defended, yet taking it pulls a key piece away from its job. The punishment might be a mate, a trapped queen, or a loss of a larger piece. The habit that guards against it is asking one question before every [capture](https://georgelichess.com/glossary/capture.md): what changes if this piece leaves its [square](https://georgelichess.com/glossary/square.md)? A rook that guards the back rank, a queen that holds an escape route, or a [knight](https://georgelichess.com/glossary/knight.md) that blocks a line can all be dragged away by a tempting pawn. If the capture removes the last defender of something important, look for the [refutation](https://georgelichess.com/glossary/refutation.md) before moving. As the player offering the pawn, you need the follow-up to be forced. If the capture turns out to be safe after all, you have simply given away a pawn. Calculate the line to the end, including the replies that decline it. Takers usually go wrong by checking only whether the pawn is attacked, not what the capturing piece stops protecting. A pawn up is no comfort if the game ends two moves later. ## Example position Black's rook can take the pawn on a2, but Rxa2? allows Re8#. The rook was the only piece guarding the back rank, and the pawns on f7, g7 and h7 leave the king no flight square. Position (FEN): `r5k1/5ppp/8/8/8/8/P4PPP/4R1K1 b - - 0 1` A neighboring idea 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. A neighboring idea is [Hanging piece](https://georgelichess.com/glossary/hanging-piece.md). A hanging piece is a piece that is attacked by the opponent and has no defender, so it can be captured for free unless its owner moves it, defends it or makes a bigger threat.
