MNb: "4.Be3 Bg7 5.Qd2 c6 6.Bh6 Bxh6 7.Qxh6 Qa5 and 8.Bd3 is too timid; 8.0-0-0 is the move, intending b5 9.e5! Safer is 8.o-o-o Be6, but I think White can maintain some advantage."
I didn't find anything worrying for Black in the following game (annotated by Zakharevich in Informator 86):
J.Geller-I.Zakharevich, St Petersburg 2002 1. e4 g6 2. d4 Bg7 3. Nc3 d6 4. Be3 Nf6 5. Qd2 c6 6. Bh6 Bxh6 7. Qxh6 Qa5 8. O-O-O b5 9. e5 dxe5 10. dxe5 Ng4 11. Qg7
Rf8 12. Ne4 Bf5 13. h3 Bxe4 14. hxg4 Nd7 15. e6 fxe6 16. Qd4 Bd5 17. a3 e5 18. Qe3 b4 19. f3 bxa3 20. Qxa3 Qxa3 1/2-1/2
But this is all very tricky and hasn't been much covered in books, so I can well imagine you could have something up your sleeve here...
I’ll respond to some of MNb’s analysis of 4 Be3 Bg7 5 Qd2 0-0 in notes to a game I played a few weeks ago – it wasn’t so well played, especially by me, but still might illustrate some ideas.

1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Be3 Bg7 5.Qd2 0–0 6.0–0–0 c6 7.f3
7.Kb1 b5 8.f3 Nbd7 9.e5?! was the above-mentioned Parligras-Jobava game. It soon turned nasty for White. Instead 9.h4 e5!? (MNb) along the lines of Ree-Donner, and also some games by Spartaco Sarno who plays this line brilliantly with Black, looks a very interesting idea; there is also 9...h5!? Black does need to resist better than in that Hall-Ghiacco game (9...Nb6?!).
7...b5 8.g4
Rushing with 8 Bh6 can get White into trouble as in Mola-Sarno (as MNb notes).
8.h4!? (MNb) has the subtle point of preventing Black's immediate counterplay with ...Qa5 and ...Be6, i.e. 8...Qa5 9.Kb1 Be6 10.Nd5 Qxd2 11.Nxe7+ Kh8 12.Bxd2 Re8 13.d5 and Black has big problems. With the pawn on g4 rather than h4, Black would have ...Nxe4! here (see below). In this position it seems insufficient.
However, 8 h4 also has a drawback: Black can hold up the kingside pawnstorm with 8...h5 (this must be played in conjunction with ...b5, not just ...Nbd7 and ...e5 as Lo Kim Lin played against MNb) e.g. 9.Kb1 Re8 10.Bg5 Qa5 11.a3 Nbd7 12.g4 Bao,Q (2376)-Sarno,S (2385)/Mallorca 2004/CBM 104 - a remarkable game by the way - and here one possibility is 12...b4 13.Na2 hxg4 with good play for Black. This was rather feeble play by White, who might try 9.Bh6 in accordance with MNb's game. But now Black's development displays its coiled spring: 9...b4 10.Nce2 Qa5 11.Kb1 Be6 12.Nc1 Nbd7 White no doubt has his birthright "plus equals" in this position, and I wouldn't fancy it against Topalov. But it looks totally playable to me (13 Nh3!? Nb6!?). I'd be curious to know the opinions of Sicilian Dragon players (and slayers).
8...Qa5 9.Kb1 Be6 10.a3?!
Here Thinius thought for a long time about 10.Nd5 but decided that the queen-exchange was no good to him. The tournament situation meant that he had to win this game, but I imagine in general 10 Nd5 is a difficult move for White to play having warmed up with Be3, f3 and 0–0–0... 10...Qxd2 and now 11.Nxe7+!? only appears once on my database, but could do with further investigation. (11.Nxf6+ Bxf6 12.Rxd2 Bc4!? as in Sveshnikov-Saricevic, is for sure a bit better for White, but I didn't mind going in for this. There has also been a nice game by Giaccio with 11...exf6 12.Rxd2 d5 which stakes Black's claim in the centre.) After 11 Nxe7+ a possible line is 11...Kh8 12.Bxd2 Re8 13.d5 Nxe4 14.Be1 Rxe7 15.dxe6 Nc5 16.exf7 d5 Again, perhaps some sort of edge for White, but does anyone have a different opinion on this line?
10.b3 b4 11.Na4 c5 12.g5 Nh5 13.dxc5 Nc6! is Yudasin-Anand (1991) - unclear at this stage but a vigorous win for Black. White's "Dragon-style" attack on the kingside has ground to an abrupt halt.
10...Qc7?!
Too tame. We both wondered about the line 10...b4 11.Na2!? Bxa2+ 12.Kxa2 c5 13.dxc5 Nc6 which I then kicked myself for not playing.
11.Bh6 a5?
A pawn "sacrifice". It was much better to take on h6 first (a surprisingly common theme in this line), so that the king doesn't get dragged to g7.
12.Bxg7 Kxg7 13.d5
Black is often pleased to see this move (producing a Sicilian structure at some cost of time to White), but here it is obviously strong.
13...Bd7
The problem is that 13...cxd5 14.g5 can't be met by ...b4 as usual because White takes on f6 with check.
14.g5 Nh5 15.dxc6 Nxc6 16.Bxb5 Rab8 17.a4 Rfc8 18.Nge2 Nb4 19.Bxd7 Qxd7 20.Nd4 Kg8 21.Ndb5 Qe6 22.Rhf1 Nf4! 23.Rf2 Qe5 24.h4 Rc4 and by now my compensation was beginning to feel plausible, though something horrible happened later (1-0).
5...0-0 is risky indeed. But in my opinion risky for both sides, not just Black. There remains much to explore in the above lines
Re JEH’s note on 4 Be3 c6 5 h3 Nbd7 6 f4 Qb6, Avrukh’s suggestion of 7 Qc1 (instead of 7 a3, Movsesian-Cekro) looks very good to me. 7…d5 8 e5 Nh5 9 Nge2 or 8…Ne4?! does look like computer chess, but what else does Black do? If the idea is 7…c5 8 Nf3, I think Black should have played the Dragon in the first place! 5…Qb6 6 Qc1 Nbd7 7 f4 might transpose. If Black wants to try an early queen move, 5…Qa5!? might be the way.
