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.
should c3 sicilian players not play austrian attack?

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
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?
