Curtains vs PoG

Note that for any move we consider here, we can interpose 30...hxg3 31.hxg3 if we desire. In some cases it might be preferable to exchange first, and in some cases not.

I was looking at 30...Qd5 31.Qxd5 Nxd5 32.Bxa7 Ra6 33.Re5

Yes good point regarding the interpose but for now there are lines where the pawn protects are king if we are driven to h7. If we exchange and he forces us to h7 he can continue an attack with Qh3+....

I think we still have the better of the position (possibly not by much?) so I'm not in favor of exchanging queens as that releases pressure.
At this point I favor the ideas with Nd5
