1.g3 opening

I'm participating in a club tournament.
I have a match with a player with whom i have played a lot of games.
He always plays modern defense with black and 1.g3 with white.
I can beat him with white(not always) but i have a problem playing against 1.g3
He always plays the pawn moves like c4, f4 at correct time and delays the development of his g8 knight.
He often fianchettos his other bishop too.
I play Austrian attack with white and have good results with it.
Is there a way to play for advantage in the opening against double fianchetto with black?
My typical opening moves go
1.g3 d5 2.Bg2 e5 3.d6 c6 4.b3 Bd6 5.Bb2 Nd7 .........
Please write any suggestion you have against this double fianchetto

I have a general system with the black pieces vs most of the flank openings. I just play 1. ... d5 (1. ...Nf6 and 2. ... d5),Nf6, c6 (creating a wall of granite for the g2 bishop to bite on), Bf5, h6, e6, Nbd7, Be7, and 0-0. It is a very solid system that really doesn't have that much book. It is the London/New York System. Lasker used it to take down Reti when he was playing his opening in the 1924 New York Tournament. It is rock solid. Sometimes, black plays for e5 (Bd6 and Qe7), and sometimes, black plays on the queenside with a5 (and maybe b5). The reason I took this system up is because I used to always go all out for a refutation. When the smoke cleared the white side would escape, and I would have a position with a lot of holes in it. While I don't recommend this setup with white (because it is hard to really get an opening advantage with it), I can really recommend it as a nice equalizer for black. Even this is fine for black.

You reminded me. I had an old chess friend who played. 1.e4 e6 2.d4 d6 followed by both fianchettos, Nd7, and Nf6 (or Ne7). He remained flexible and played it from their. He got the idea from an old Soltis pamplet on 1. ... P-QN3. There it was called the MacLeod System. Spassky has used this setup at least a couple times. Anyway, it used to give me fits. Whenever I played e5, he played d5 and vice versa. I was really weak in those days, but I don't think he lost a game with it. It and the Dutch Leningrad were his only two defenses. 🙂

Thanks for the replies
The London system seems to be very solid.
I'm also thinking about fianchettoing my own f8 bishop with 1.g3 g6 2.Bg2 Bg7 and go into a kind of symmetrical grunfeld.
Have to think about which one to choose.
I will inform you how the game goes later.
Thank you very much for the suggestions.
