Maybe it is just me, but after 20.Rh3 a5 Black's attack looks quite frigtening to me. I am not sure about 20.Ne2 a5 21.c3 a4 either.
My superficial analysis runs 20.h4 a5 21.h5 a4 22.Bxc4 (not hxg6 too soon) bxc4 23.Nd2 a3 24.b3 cxb3 25.cxb3 (with 22.hxg6 fxg6 included Black has 26...Rf8!?, which now is met with 26.f5) and no matter what computers say, I like White here.
It's been a while since I looked at it, but I remember not liking the idea of allowing Black to keep the h-file closed by playing ...g5. After 25...Ba6 26.Qf3, have you looked at
26...g5 (whiteatak shredder's 26...Bc5 also worries me a bit) 27.fxg5 Qxg5 or the immediate
24...g5 (iso 24...cxb3)? I'm not saying White is in danger in these lines, but I'm having trouble convincing myself that Black is suffering.
It's certainly possible that I may be underestimating Black's play in the 20.Rh3 line (I hope not!), but at least I have an idea of what White's trumps are and how I should proceed.
I'll try to get a better handle on 20.h4 and, if I can, I might be convinced to play it. Right now, however, the merits of the line just elude me. Forgive me if I'm just being obtuse - it's not deliberate.
