Pawn Endgames: Triangulation

The Pawn Endgames: Triangulation is a pawn endgame involving K+P vs K+P. Triangulation is a technique where one king maneuvers in a triangle to lose a tempo and put the opponent in zugzwang. Your king takes three moves to reach a square it could reach in one, effectively passing the move. This technique converts many positions that would otherwise be drawn. It appears simple but is one of the most missed winning techniques in club-level chess.

The key concept in the Pawn Endgames: Triangulation is: Losing a tempo with the king. Understanding this principle is more important than memorizing exact move sequences — once you grasp the underlying idea, you can navigate the position even when the move order varies slightly from the textbook line.

Pawn endgames are the most important endgame category for every chess player — they appear constantly in practical games and the principles (opposition, key squares, the rule of the square, triangulation) underlie almost every other endgame type. Mastering the Pawn Endgames: Triangulation gives you a foundation that pays off at every rating level.

Set up the K+P vs K+P position on a real or virtual board and play it out against an engine or a training partner. Once you can win or hold the position consistently from the textbook setup, try harder starting positions where you have to find the right plan from scratch.
