Pawn hook

A pawn hook is a pawn that another pawn can attack to create contact and open a file or diagonal. It is especially important in front of the king, where pawns form a protective shelter. Once one shelter pawn advances into reach of an enemy pawn, the attacker no longer has to strike an intact wall; there is a specific point to pull against.

The hook is not the break itself. The hook is the target or contact point, while the break is the pawn advance that attacks it. After exchanges, a file may open for a rook or a king defender may disappear. The same idea can dismantle a pawn chain elsewhere and cause a pawn-structure transformation.

Usage is not completely uniform. Some literature calls the exposed enemy pawn the hook, while some coaches apply the word to the pawn move that permits the later break. The shared idea is that a pawn advance creates a surface the opponent can exploit. A hook therefore often produces pawn tension, but it does not guarantee that opening lines is correct immediately.
