Thanks a lot yeres30 and Cogwheel for the clear explanation what a triangle travel of the White king is.
What is "Triangulation"?
Hmm.. then how about this:

@aberki1234 Your mainline is wrong. 3. Kg2?? loses; 3. Kg4 draws.
After 4. Kf2 Kh5! and black wins by entering. 5. Kf3 Kh4; 5. Kg3 Kg5.

Good point I didn't see that. I knew Kg4 definitely drew, but I decided it was too simple. xD

Triangulation is a trick which is mostly used in end game position to get upper hand over the opponent and finally wins from the drawing position.Take a closer look into the following end game.
