Pawn Structures – The Soul of Chess

"Pawns are the Soul of Chess" – Philidor

In chess, the pawn structure (or pawn skeleton) is the configuration of pawns on the chessboard. Since pawns are the least mobile pieces, this structure is relatively static and largely determines the strategic nature of the position.

Weaknesses such as isolated, doubled, or backward pawns are usually permanent. However, context is everything—sometimes a "weakness" like doubled pawns can offer dynamic compensation (open lines or control of key squares).
