Triangulation
In chess, Triangulation is a technique used to "lose a move" by making a triangular path with the King. With this maneuver, the King, instead of returning to the original square after two moves (going back and forth), returns to it after three moves. This technique is often employed in endgames to put the opponent in zugzwang, forcing them to make an unfavorable move.
In the diagram above, it's White's turn to move, but in order to make progress, White would love it to be Black's. White therefore triangulates with: 1.Ke5 Kc6 2.Kd4 Kd7 3.Kd5, and now the position is the same, but it's Black's turn to move, and White can penetrate the position and win.
