Does This opening exist?

I was wondering if this opening exists already because I loved the results I got with white!

I don't think it is exactly like that, but with a different move order that is basically a KIA(Kings Indian Attack). You should look up the KIA in the Book Openings section.

no, not really

4.g3 makes this the Glek system of the Four Knights Game. Look for games where Glek played this as White for a guide.

Dude, it's pretty much sicilian, mixed with zukentort, mixed with hungarian, and a KIA.

It does "exist," but unless your opponent plays into your ideas, I doubt it'll be perfectly effective EVERY time.

It's a four Knight's game in which you fianchettoed on the Kingside, not normally done, but not completely crazy either. 

Don't fall too much in love with this, as black doesn't have to allow it.
