A question

Black's h5 doesn't help, as white ignores it, and if black pushes to h4 creating
a protected passer on h4, the white bishop holds it back.  After h5, gxh5 gives
black an entry so white doesn't want to do that, but if he doesn't, can not
black play hxg4 and now black has a king-side entry square if white tries to
walk to the queen-side?  So I don't see how white is going to be able to leave
the kingside with the white g-pawn gone, as black can push its g-pawn, make
white sac the bishop for the first one, and then the second/third walk in.

IE this looks drawn to me, without computer analysis.

For example, you play Be4, I play h5.  Now what do you do to win?

I may be overlooking something simple, as I didn't spend a lot of time
looking, but it doesn't look promising to me...
