so how to manage a okay opening stage? any tips? the opponents have around 900 elo skills. I tried to play the indian defences but they have two pawn moves...
serious trouble. help?

All e4 openings cut out? All crazy pawn sacrifices? All open wild tactcial games gone? What a sad game!
Fairly simple opening you could play is this.
Just remember if you spend two tempo's to get a pawn two squares forward they have to spend two tempo's to counter it with a pawn push of their own.
in my univ they play a different kind of chess which differs in that you can never move a pawn two squares.
