Excellent!
Endgame Study - A. Belyavsky, 1982.

Good one.I was not able to solve it correctly at first go, another interesting variation is where instead of Kg2, e2 is played and promotion to queen actually leads to mate. White has to promote to knight to stay in-game( still losing)

Yes indeed but the K promotion is really helpless.
White to play and win.
