I've known it as the Ultra-fianchetto.

Can't white defend the e pawn in other ways, or meet 4...Nf6 with 5. e5

Lately, I prefer 3.c4 followed by d4 to avoid 3.d4 cxd4 4.Nxd4 Nf6 Nc3 which blocks the c2 pawn. ***EDIT*** after 3.d4 cxd4 4.Nxd4 Nf6 5.e5? Qa5+ followed by Qxe5 wins a pawn. It is possible to play 5.f3 but it will lose a tempo if white intends f4 later. And of course, 5.Bd3?! doesn't seem good at all.

I also don't like 4.Qxd4 for the same reason.

Qd4 losing a tempo

I'd consider the Q recapture, unless I was steering towards a Maroczy Bind set-up. That is probably why a quick c4 (at move 3, say) has something to be said for it in this line.

Making use of black not playing 4...Nf6 first.

For mine, a toss-up between c4 and Nc3. If the coin landed on its edge then c4...  

6.Nc2 does come into consideration.

Nc2 allows Bxb2

Erm if white plays 6.Nc2 the bishop is still in c1 protecting b2

The alternatives, Nxc6 and Nf3, look playable, but unenticing. Can't say I go a bundle over Nc2, neither. This bishop development would be my likely choice.

That isn't really developing 'with tempo' unless White is planning something other than the move it induces.

I prefer 7...Ng4 8.Qxg4 Nxd4 9.Qd1 Ne6.

8.f3 is the other move, but I prefer the Be2 move myself...

But Black could play 9.Ng4 here. For that reason I might have preferred 9.f3.

although the exchange of his dark-squared bishop for a knight is one of the strategic objectives for Black in the accelerated Dragon.

I don't think white normally queenside castles in the maroczy bind. Also one black strategy black can use in this set up is to welcome the exchange of dark square bishops then relief upon the dark squares as good posts for his pieces

9...Ng4 was a good alternative.

Be2 now become weak bishop because all its move blocked by white pawns I prefer 0-0

White has a better position for grinding black down, castlings queen side is only inviting an unnecessary knife fight. The main problem is that whites played c4 already opening the queen side up a little, when black plays his thematic ...b5 he will already have something to bite at.

I don't like castling queenside if white played c4 especially with a black fianchetto bishop on g7, Instead I prefer O-O, Rac1, Rfd1.

I would have castled short, myself. But long castling is by no means fatal, and at least brings a rook more quickly to the semi-open file. I think, though, that I would have preferred the King's rook on d1, with the other on c1. So 11.Rc1 also came into consideration.
