Do some research and look up "Yugoslav Attack". That's all you need to know. Better for you to read a book like Chess Developments: The Sicilian Dragon, study, and understand it than for us to spoon feed you reams of lines with no explanation or in many cases, with all the fools on here, wrong information. Go to Amazon.com and pick up that book mentioned. Most other dragon books are written for black. The Chess Developments series is objective. I have the ones on the Najdorf and Grunfeld.

There is also a rather similar thread, on the same page...Not to mention others from more distant past.

I would try this first, not the Yugoslav Attack. The Yugoslav Attack is better, but this line becomes critical more quickly and most Dragon players don't know it.
Anyway, you will run into a lot of false information regarding this variation. Make sure to check all of it with an engine.
I just downloaded Arena, and was surprised when it began playing The Dragon against my 1. e4. I used to play the Dragon a lot, so I was familiar with the Yugoslav Attack, which tends to destroy the Dragon. However, my computer killed my Yugoslav playing this line, which I had never seen before:
Hey guys. I would be thankful to know about some lines against the dragon
