Learn How to Win a Pawn Endgame: Zugzwang
This chess endgame is a classic example of using king activity to create zugzwang. With the material balanced and both sides reduced to pawns and kings, the side to move can often be forced into a passive king move that concedes key squares. In positions like this, the strongest plan is usually to improve the king first, then use opposition and space to restrict the enemy king. Small tempo gains matter more than material count in classical chess endgames.
