Slaying The 9. O-O-O Nxd5?! Dragon - According to Vigorito

Another nice correspondence game I just finished.  I followed David Vigorito's new book "The Sicilian Dragon" all the way to move 24, and used a tactical motiff he mentioned several moves further.  The win was quite certain by the time I left preparation.

I strongly recommend the book to all Dragon players. 

Here's the game, with a few of my personal notes.
