What is the current theoretical state for the Chinese Dragon? I use this line a lot, as it tends to lead to interesting games, and I was wondering whether any advances in theory have been made here.

[FEN ""]
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 7. f3 O-O 8. Qd2 Nc6 9. Bc4 Bd7 10. O-O-O Rb8


Wikipedia
When black plays the Dragon, recently, the top players tend to choose 9.0-0-0 and 9.g4, instead of 9.Bc4. For example, Topalov-Lu Shanglei, Wei Yi-Lu Shanglei, Caruana-Nakamura and Karjakin-Nakamura.

According to the Game Database of ChessTempo, after 9.Bc4 Bd7 10.0-0-0, 10....Rc8 is the most popular choice. A couple of months ago, two books about the Dragon have been published, written by GM Jones. In Volume 1 he recommends 10....Rc8 and a couple of days ago, he used this move to beat GM Yu Yangyi.

However, according to the Game Database of ChessTempo, 10....Rb8 scores close to 50% with a performance of 2410, for players with an average rating of 2407. This indicates that 10....Rb8 is a good alternative for 10....Rc8.

White usually continues with 11.Bb3. After 11....Na5 12.Bh6 Bxh6 13.Qxh6 b5 14.g4, white does seem to be slightly better. Recent games of strong players are: Mamedov-Can, Ledger-Jones, Saric-Cvitan, Demchenko-Kanter and Georgiadis-Cvitan.
The same position can arise after 12.g4 b5 13.Bh6 Bxh6 14.Qxh6.
