Some 2200 USCF thinks he has found some refutations to the Dragon based on the 9. 0-0-0 variation. I don't play the opening so im not sure. Here is a link to his claims in a thread on some other forum. Does he seem correct?

Interestingly, he doesn't have anything to say about 10...Rb8 except that it 'misplaces the rook'. Clearly Carlsen had other ideas when he played this against Nisipeanu.

Magnus plays the dragon, inspite of Garri`s Najdorf influence, so it must be definitely playable.
  
The older, the better - over 2200 and still rising.

FYI, I believe the analysis referred to ("Rybka, as well as this GM") is by Dzindzichashvili in Sosonko’s Corner NIC Yearbook 91.

There is also a survey in NIC Yearbook 94 mentioned by bragesjo in an earlier thread.

The guy seems a little nutty. I read more of what he posted. He basically just turned on rbyka. He doesn't address either exf6 or Rb8. Since I started this thread I have spent a few hours researching these lines. I wouldn't mind playing the black side after exf6 or Rb8 honestly.

The main Varuation runs...

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 7. f3 Nc6 8. Qd2
O-O 9. O-O-O d5 10. Kb1 Nxd4 11. e5 Nf5 12. exf6 Bxf6 13. Nxd5 Qxd5 14. Qxd5
Nxe3 15. Qd2 Nxd1 16. Qxd1 Be6 17. Bb5! The idea is to exchange the white squared Bishops, leaving White with a winning position.

All the other side variations, having been shown as better for White.

17.Bb5! does look good for White to me but wasn't 12...exf6 still considered playable for black?  I know this has been analyzed a lot here on the forum.  Also what is White's refutation of the interesting 10...Rb8!? variation?
