I couldn't find much sources on this opening.
I'm teaching my young students for them not to bother with opening theory in their early chess experience.
I push it as far as playing it black or white. Having this position no matter what (if the opponent is playing decent moves) with white:
[FEN ""] 1. g3 e5 2. Bg2 d5 3. d3 Nc6 4. Nf3 Nf6 5. O-O Be7 6. c4 Be6 7. Nc3 O-O 8. a3 a5 9. Rb1
Same goes for black (g6 etc ...).
The idea behind this is securing our king fast, and launching an attack on the queenside while strenghtening the diagonal of our bishop on the kingside.
Next we want to prepare b4. I don't really know what to do with my dark-squared bishop though.
If some of you could give me some good advice or insight on this opening (is it good? Bad? What are the plans?) that would be awesome.
