Chinese Dragon

Hey, what are your opinions on the Chinese Dragon? I couldn't find much information on this variation of the sicilian online. Basically all I could find was black my sacrifice the b pawn for open files for his rooks and queen. It would be much appreciated if some players of this opening could post some lines, thematic ideas, or approaches to this interesting variation of the yugoslav sicilian. Thanks a lot! 

Below, I will post the Chinese dragon line

There is an article available on line that gives a good intro. In ChessCafe by Gary Lane, here's the link: http://www.chesscafe.com/text/lane117.pdf

Thanks mnag! Personally, do you think it's useful to add to a dragon player's repertoire?

Yes, I have tried it a couple of times without success but also without a great deal of study. So any different wrinke you can toss at an opponent who already knows that you play a dragon would give him pause to think.

thanks for the link to the article. useful
