Thinking little more over the past year, there was also several articles about dragon.

New in Chess yearbook 91 has for example objective view about Chinese Dragon (while only mention a chesspub pawn sac (e5 instead of b5 in Bh6 line) in passing).

There was also an small article in a SOS book (11?) where Tiviakov proposed a new concept with Be6 and delaying castling, but I think white is better there.

There was also a DVD by Dzindzi called "Dragon in Yeapardy". Unfortunnaly local store never took this is so I have not seen it myself but it was a white repertoare with 9 0-0-0 yugoslav meeting d5 with Kb1 where the now fasionable line where black takes exf6 was considered as none serious option being dismissed after 10 seconds and 0 moves.

Also the book Chess Openings for Black Explained got updated with a 2nd edition but I dont play accelerated dragon so I have not looked what the updates are about.

2009 Dragon theory developments

I thought that we could summon up whats has been happening theorticelly over the past year
Here are some starting thoughts

New reference book for white : Opening for White according to Anand volume 11
New reference book for white : Dismantling the Sicilian

Conclusion: Both books recommends Bc4 Yugoslav and Bc4 yugoslav like but sometimes preferces different moves in different positions.
Black seems to have surived both books since Dragons are still played.

New reference book for black : The new Sicilian Dragon (first Dragadorf and Acclerated Dragadorf book)
New refernce disc for black : ABC of the Sicilian Dragon (Dragadorf disc)

Conclusion: Both are about Dragadorf but the wierd thing is that The new Sicilian Dragon did not give any refernces to the disc...
Also, I have not seens any major increase of Dragadorfs or Accelerated Dragadorfs.

************************************

Classical lines: Kamsky - Radjabov showed that Be2 0-0 Be3 Qd2 system allows black to equalice by playing d5

Yugoslav 9 0-0-0:

Experts vs Sicilian line: 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. O-O-O d5 10. exd5 Nxd5 11. Nxc6 bxc6 12. Bd4 *

Black seems to be fine in both Bjerring variation (Nxc3) as well as in Bxd4 Qxd4 Qb6 variation. Have not seen any high
level encouters in e5 line, unclear why.

The line
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. O-O-O d5 10. Kb1 Nxd4 11. e5 Nf5 12. exf6 exf6 13. Bc5 d4 *
Has been played by both Radjabov and Carlsen och seems to hold up well for black.

Yugoslav 9 Bc4
Karjakin-Shirov seems to be the most notable development over the past year.
Dominiquez-Smerdon could also bee an importent game as well as Vachier Lagrave-Kasimdzhanov.

Soltis defence still seems to be solid as ever, Chinese variation seems to bee in excellent shape as well.
