should c3 sicilian players not play austrian attack?

i play the c3 sicilian and the austrian attack but im facing this guy that start with g6, Bg7 and do waitingmoves. if i play Nc3 at some point he plays c5 and i cant use my c3 sicilian. on the other hand if i keep c3 available and do something like Nf3 instead he goes into pirc/modern stuff and since i played Nf3 i got no austrian attack. should i just abandon the austrian attack?

In this case I would look for waiting moves for white or go for f2f3 setups.

That can work fine against Pirc/Modern (Saemisch) as well as against Sicilian (English attack).

I like it very much myself. f2f3 is flexible and solid. It covers the e4 pawn, and it prevents a possible Ng4 or Bg4, and gives you the g4 push option. And you can still choose to play 0-0 or 0-0-0 after f2f3.

Here's an example of a game with f2f2, where I played an idea that I saw in a game from GM Timman years ago.

White plays Ng1-e2-c1-b3.

You can play 1.e4 g6 2.d4 Bg7 3.Nc3 c5 4.d5 and get a Benoni w/ the knight on c3 or you can try 4.dc Qa5 5.Bd2 Qxc5. I don't think Black should be allowed to capture on d4 in any case unless you simply want to play the dragon.

so ive been trying out some lines since last time. after trying 1.e4 g6 2.d4 Bg7 3.Nc3 c5 4.dxc5 which is also recommended above i always get an easy to play game where black struggles so i dont care anymore about this line, and i can keep both my c3 sicilian and austrian attack.

i found out 4...Qa5 needs a bit work but its worth it to make those sniperplayers as the 3...c5 players call themself feel they should have bought another openingbook
