Learn How to Win a Pawn Endgame: Zugzwang
This chess endgame is a classic example of how a small pawn detail can decide the whole position. Even with material close to equal, the side to move can be forced into a losing sequence because the king and pawns are tied to specific squares. The key idea is that a well-timed capture can transform the structure, create a passed pawn, and leave the opponent in zugzwang. In practical classical chess, these positions often look harmless until the tactical refutation appears.
