Surely the hardest chess problem ever!!

Suppose that Black had the move, and promoted to a Queen. Then White could play Nxh4, and the Knight could not be captured. White can follow with Nhf3, and then Black could not achieve anything because his King is stuck (and therefore also the Pawn on h6) So White needs a waiting move with his King. If he plays 1.Kd6 g1=Q,2.Nxh4 Black saves his Queen with Qb6+ and then takes the Knight. The only move that does not provide such a resource is 1.Kc6 which therefore draws, since 1.. h3 can be answered with Ng3+. My computer actually gives this line but does not realize that the position is drawn, evaluating it at about -6.0 . It cannot understand the word never.
