Perpetual Check Puzzle (Rated 1500): Repeat Moves — Chess Endgame
This chess endgame is a classic task-repetition pattern where the side to move must use king activity and precise triangulation to hold the draw. With only kings and a passed pawn on the board, every tempo matters. The stronger side wants to advance the pawn and create zugzwang, while the defender must keep the king in front of the pawn and avoid being pushed away from key squares. The lesson is that in simplified positions, repetition can be the most practical defensive resource.
