Possible draw for white?!

I found this position in a tactic. Should be winning for black, but if you look closer... Can details show us a draw?

hmmm, maybe Qe5+, but I'm struggling to find anything after ....Ka8

King will escape on b7 probably...

Either draw by repetition or black would lose it.

I am not so sure because of interesting b&c pawns. What about 1.g6? Seems dangerous.

g6 is interesting!

edit: I posted before seeing IMphren's post

I haven't solved it, but 1.Qe5+ "almost" make it a draw. Need to improve 2 lines into a draw instead of loss (main line below and 8...Qb6)

Thanks for solving that mistery! 5.Nd4! is very impressive move.

pfren's line seems to be working to me. I agree it is beautiful.

But the best thing is, that engine can't see the draw until Nd4. I checked some variation later then, and came to the Nalimov with winning white. So early perpetual is the only chance I think.

This is quite cool. Though, I don't think Black has lost... yet.
