Also, I'd be very interested in learning what the database says here.
I really need help learning this opening

I checked the largest database I have access to, the 6 GB GigaKing database the comes with Chess King, and there's not a single example of the position after 4 d3 being reached but, by transposition, one game -posted at the bottom of this message- reached your position if Black plays 4...d5 in your opening. Unfortunately, it a Black win, though it's played between two OTB high-rated players and it was a close-game right through the endgame. In the game below, White chose a Pawn Storm on the Queen Side even though both of Black's B's were pointing to that side and White didn't have a significant material advantage there. Still, White succeeded more than I expected he would, though Black held on and, at one point, went up a P.
As you say, your opening restricts Black's Knights, but it also restricts White's Knights from what is usually their best first-move positions. That doesn't mean it's a bad opening but it means you have to be creative about attacking moves, because if you are too defensive Black should equalize or better quickly: after 4 moves, all P-moves, only your Q and QB can do any threatening.
I've been studying openings recently, and I discovered something really novel and cool.
However, I need help learning the theory and ideas behind this opening. Also, I want to know is it good or not? And what openings would you compare it to?
There is a very special idea behind this opening as white - restrict black's knights. Notice how the center pawns do this. I've played some sample games against 2000+ players, and this works OK, but I still need work.
Can someone suggest to me theory and possibly some master games so I can learn this opening better and improve my play? Thank you.
