Learn How to Win a Pawn Endgame: King Activity
This chess endgame shows how king activity can decide a seemingly simple pawn race. Even with extra pawns, the stronger side must use the king aggressively, because in classical chess the king becomes a fighting piece once the board is reduced. The key idea is to centralize, create a passed pawn, and force the defender into passive squares. Small tempo gains matter, and a single inaccuracy can flip the evaluation in a pawn endgame.
