In the endgame, isolated pawns are a weakness in pawn structure because they cannot be defended by other pawns as with connected pawns. In the diagram, the white pawn on e4 and the black pawn on a7 are isolated. Isolated pawns are weak for two reasons. First, the pieces attacking them usually have more flexibility than those defending them.

The pawn (♙, ♟) is the most numerous and weakest piece in the game of chess.It may move one square directly forward, it may move two squares directly forward on its first move, and it may capture one square diagonally forward.
The backward pawn also prevents its owner's rooks and queen on the same file from attacking the piece placed on the hole. If the backward pawn is on a half-open file, the disadvantage is even greater, as the pawn can be attacked more easily by an opponent's rook or queen on the file. Pieces can become weak when they are devoted to protecting a ...
While Black's position is cramped, it is also relatively free of weaknesses. There is no obvious way for White to attack Black's pawn structure, but as outlined above, Black has several methods at their disposal for creating counterplay. Thus the Hedgehog has retained its popularity as a system of development in modern praxis.
A pawn storm, sometimes called a pawn avalanche, [1] is a chess tactic in which several pawns are moved in rapid succession toward the opponent's defenses. [2] A pawn storm usually involves adjacent pawns on the flank of the board, such as the queenside (a-, b-, and c- files ) or the kingside (f-, g-, and h-files).
