What is Triangulation in chess?
A king maneuver that loses a tempo to reach the same position with the opponent to move.
By tracing a triangular path, the attacking king returns to the same square but with the opponent now having to move - which puts them in zugzwang. Triangulation only works when the attacking king has more room to maneuver than the defending king.
