White to play and win (or not, perhaps)

Whilst I think the problem is cooked, it is nevertheless a good exercise. I think White's attack can be defeated. How?

Solution

White's first move is obvious, 1 Ngh5, but black isn't forced to capture- if he does, g6 comes, with ruinous opening of lines. But if black declines, my analysis to date shows that I think Black can just about defend – though the narrow drawing line is only obvious if you are made of silicon- the line isn't mine, but Houdini's. I think the drawing line is little short of miraculous.

I attach my analysis to date. I wouldn't be too surprised if further engine power changed the evaluation. The problem is Aagaardian, capable of extensive analysis.
