Pawn wedge

A pawn wedge is a formation whose most advanced element penetrates enemy territory and divides or restricts the opposing structure. It may be one deeply advanced pawn supported from behind or a small pointed group. The term is used somewhat broadly, but the shared image is a wooden wedge driven between two parts of the position.

The wedge gains space and controls squares that enemy pieces would like to use. It may also stop opposing pawns from advancing together, support a piece near the king, or prepare a break. Its value does not require an immediate run toward promotion; sometimes its main job is to keep the opponent tied down and short of useful squares.

The advanced tip can become a target if its support disappears. The opponent often tries to blockade it, attack its base, or exchange the pawns that sustain it. It is therefore important to identify the pawn-chain base and decide whether the wedge should remain fixed or take part in a pawn-structure transformation.
