Triangulation #2: A nice, slightly more difficult example
Triangulation is a tactic used in chess to put one's opponent in zugzwang. That is, it gets to the same position with the other player to move, when it is a disadvantage for that player to move, e.g. he has to give up a blockade and let the other player penetrate his position. Triangulation is also called losing a tempo or losing a move. (Triangulation (chess), wikipedia)

Now let us look to the same position, but now with White to move:
Though White's king was under fire and Black could use a stalemate combination and a Black rook has gone wild, White managed to swap the duty to move by moving his king in a triangle.

As icing on the cake the composer, Romanian economist Emilian Dobrescu, gave the problem a nice introduction:
