A pawn storm is a chess tactic in which several pawns are moved in rapid succession toward the opponent's defenses.[1] A pawn storm usually involves adjacent pawns on one side of the board, the queenside (a-, b-, and c-files) or the kingside (f-, g-, and h-files).
A pawn storm will often be directed toward the opponent's king after it has castled toward one side (e.g. Fischer–Larsen, 1958[2]). Successive advances of the pawns on that side might rapidly cramp and overwhelm the opponent's position.

A pawn storm might also be directed at queening a passed pawn; the diagram is taken from a game in which Tigran Petrosian was playing the black pieces against Bobby Fischer. Over the next fourteen moves, Petrosian storms his twin pawns down the a- and b- files, forcing Fischer's resignation.
