GM Igor Smirnov has videos about the subject but i'm usually very suspicious about what he says/recommends.
books on sicilian ,prins var.
One option is to play 3...Nf6, when 4.f3 isn't possible yet. If they play 4.Nc3 then 4...cxd4 5.Nxd4 and you're back on track, but you need to have a plan for what you're going to do after 4.dxc5.
Is there any book on Sicilian, Prins variation (1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. f3) ?? every1 is playing 5.f3 so that they can play c4.i want to avoid that
