For all the Dragoneers,

I just thought you should know that the idea of 10.0-0-0 for white makes it quite easy to equalize with 10...Rc8. This was played twice in Masserey vs hoffman-1994 and again in 1996 in Dean vs. Rodriguez. Black won both matches. 

I do believe that an improvement could be found in Dean vs. Rodriguez 

1. e4 c5 2. Nf3 d6 3.d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6.Bg5!? Bg7 7. Bb5+ Bd7 8. Qe2 a6!(given by Ivanchuk in chess informant 65 I believe) 9.Bxd7 Nbxd7 10.0-0-0 Rc8! 11. f4 0-0 12. e5 dxe5 (here the game went 12...Rxc3 13.exf6 exf6 14. bxf6 Nxf6 15. bxc3 Qa5) 13. fxe5 Rxc3 with the same idea as the game but without the vunerablity of d6

I see the point:
with the Queen in e2 the Rook sacrifice on c3 is stronger! 
With 8...a6 Black can reach both a fast development of the Rook in c8 and the opening of the c column.

By the way in Taiko's line 
1.e4 c5 2.Nf3 d6 3.d4 cxd 4.Nxd4 Nf6 5.Nc3 g6 6.Bg5!? Bg7 7.Bb5+ Bd7 8.Qe2 a6! 9.Bxd7+ Nbxd7 

he omitted White's 10th move (000 or h4).

After 10.h4 h6 I believe Black is really better
After 10.000 h6 White can play, according to me, 11.Bxf6 Bxf6 12.f4 Rc8 13.Nd5!? trying to justify  the opening

I have met this move once, even though I don't play the dragon very often, and I can say it's very interesting. White can easily exchange black square bishop or built up an attack with Bh6, h4, h5 etc. In comparison with the Yugoslav, I felt through the game that even though it was an interesting game with both sides playing for a win, it was not as complex as the Yugoslav. I could even say that the plans were rather simple instead! With only one practical experience and very little research, I would say that this move is very playable, especially if you are an attacking player and you want to surprise your enemy, but if your enemy is a good defender then do not expect too much
