A backward pawn is one that has fallen behind the pawns on its neighboring files and can’t advance safely, because the square in front of it is controlled by the enemy. Its friendly neighbor pawns have marched ahead and left it stranded, unable to catch up.
Two things make a backward pawn a headache. First, it usually sits on a half-open file — the enemy has no pawn there — so their rooks and queen can stack up and lean on it directly. Second, the square right in front of it is a permanent hole: since no friendly pawn can ever guard that square, the opponent parks a knight there and the pawn is frozen forever. It’s a weakness that just sits and waits to be attacked.
Why it matters
The backward pawn is the poster child for “static” weakness — it won’t run away, so the attacker can build up against it slowly and squeeze. The classic example is the backward d-pawn in many Sicilian lines: Black gains active piece play, but has to keep an eye on d6 and the gaping hole on d5. If you own a backward pawn, your job is to trade it off, push it forward at the right moment, or generate enough activity that the opponent never gets to collect it.

Backward d-pawns are a defining feature of the Sicilian Najdorf and Sicilian Sveshnikov. The pawn’s biggest gift to the enemy is the weak square in front of it, which becomes an outpost. It’s a sibling of the isolated pawn and often gets attacked down an open file. Browse the full chess glossary.
Mini-FAQ
How is a backward pawn different from an isolated pawn? An isolated pawn has no neighbors at all; a backward pawn still has neighbors — they’ve just advanced past it and can’t help it move.
Can a backward pawn ever be fixed? Sometimes — by pushing it forward when the square ahead is finally safe, or by trading it off. The trick is doing it before the opponent piles on.
