Pawn Endgame Puzzle (Rated 1540): Win a Pawn Endgame — King Activity
This chess endgame is a classic lesson in king activity and pawn structure. Even with equal material, the side with the more active king and the healthier pawn majority can force a decisive result. The key idea is to create a passed pawn, use it as a decoy, and keep the enemy king tied down. In pawn endgames, tempo matters enormously, so forcing checks and pawn advances often decide the game before the opponent can organize counterplay.
