I agree the whole line should be equal, but not this particular sideline with ...Bxd4?! Be interesting to see the analyisis of h4!? by Renet but White has so many other good moves here I dont think it matters too much. Playing Qa4 is not one of them I would have thought though, but I'll give that line a look. It just seems a bit awkward to me that plan of Qa4-a3
After 12.Bxg5 Qxg5 13.h4!? Qh5 it seems to me Whites simplest is 14.0-0 and follow up with f3 blocking the bishop out and the blockading Na4-c5. Black can grab a pawn but he ends up being dominated by the Knight: e.g. 14...Qg6 15.f3 Qxc2 16.Rf2 Qg6 17.Na4 My computer engine slightly prefers Black here but it has obviously never read Nimzowitsch - White will get a nice bind after Nc5 with domination as compensation for the pawn. All I know is in a real game playing against a human Black is going to have problems. Maybe I'm wrong but I think White has to be prepared to give a pawn here and there in this line if required. The Estrin game also looked very safe for White though with no sacrifices, I think only White can win those opposite coloured bishop positions even if the absolute correct result should be a draw
Renet merely says that after 12.Bxg5 Qxg5 13.h4!? Qh5 "Now the pawn on h4 looks a bit strange" and quotes the example game Arnold-Donev 1997 without comment.
It might be significant that the 5. e5 expert Okhotnik has reached the key position after move 11 twice; the first time he played 12 Bxg5 Qxg5 13 g3, but later he switched to the Estrin plan of 12.0-0-0 Ne6 13.Qa4 Bd7 14.Qa3. He won both games.
I was amused by this game, which shows what is, at first sight, a model counter-attacking plan for Black if White goes for the Qd2, 0-0-0 set-up:
Van Tonder,Ronnie - Kobese,Watu (2399) [C56]
RSA m Cape Town (5), 31.07.2002
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d4 exd4 5.e5 d5 6.Bb5 Ne4 7.Nxd4 Bc5 8.Be3 0-0 9.Bxc6 Bxd4 10.Qxd4 bxc6 11.Nc3 Ng5 12.0-0-0 Ne6 13.Qd2 Rb8 14.f4 f5 15.a3 Qe7 16.Rhg1 Ba6 17.g4?! Rxb2! 18.Kxb2 Rb8+ 0-1
Very neat you might think but in fact White could have fought on with 19 Nb5! after which things are far from clear (to me anyway

).
