A passed pawn is a pawn with a clear road to promotion — no enemy pawns on its own file, or on either neighboring file, standing between it and the last rank. Nothing but enemy pieces can stop it, and pieces get tired of chasing pawns.
That’s what makes a passed pawn such a big deal. Every pawn dreams of becoming a queen, and a passed pawn is the one with an actual shot at it. It forces the opponent to spend a piece blockading it, which drags their army off other jobs. As the old Nimzowitsch line goes, “a passed pawn is a criminal that must be kept under lock and key.” The further it advances, the more it ties the enemy in knots — and in the endgame, it often just walks in and promotes.
Why it matters
Passed pawns win endgames. A protected passed pawn (one guarded by a friendly pawn) is especially nasty because the enemy king can’t simply capture it. An outside passed pawn — one far from the main action — is a classic winning tool: it lures the enemy king away, then your king cleans up on the other wing. Whenever the board simplifies, the player with the healthier passer usually holds the trump card.

A passed pawn is often the flip side of a seventh-rank rook and the reason an isolated pawn can still be dangerous. More in the chess glossary.

What’s a protected passed pawn? A passed pawn defended by one of your own pawns — the enemy king can’t just grab it, which makes it extra hard to stop.
Is a passed pawn only useful in endgames? It’s strongest there, but even in the middlegame a far-advanced passer can cramp the opponent and tie down their pieces.
