I've just started to play Sicilian, and really like to get into the dragon. Just know studying Wards last book on it. I have also picked up some anti-sicilian books to cover up alternate white approaches to 1.....c5.

There is one variation in the classical line of the dragon thats not covered in the book from Ward, and goes like this:
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 Nc6 6. Be2 g6 7. g4!?

What's the name of this line, and can I find any books on it, anyone?

Thanks in advance
