Isolated pawn

Concept, intermediate

Also called Isolani, IQP.

A pawn with no pawns of its own side on the files next to it, so no pawn can defend it.

An isolated pawn is a weakness in the endgame, because pieces must defend it. In the middlegame it can be a strength, giving open lines and outposts for an attack.
