ColonelCrockett: I think I can say with confidence that there is absolutely nothing wrong with 2.Nc3 and if you ever want to try it with 3.g3 you should be able to find some good books. Spassky was a specialist in the Closed Sicilian and collected many scalps! The Grand-Prix Attack following 3.f4 is also well covered. As for the system with Bc4 and d3, you're right, I haven't seen much on it. Probably because, while somewhat popular at the club level, it is practically never seen in grandmaster games.
