Plain-English Definition
The pawn structure tells you which pieces want the game to breathe and which pieces want it locked.
Why It Matters
It is a core scale for deciding trades, breaks, and piece improvement.
Common Signs in Games

- Pawn chains point toward the side to attack.
- Knights have stable squares in closed centers.
Common Mistakes

- Keeping a closed structure when your rooks need files.
- Playing pawn breaks before pieces are ready.
