I was wondering what people suggest against the Petrosian System in the Gruenfeld. I'm "club strength" and am just starting to learn the Gruenfeld. I'm especially curious about this c5-b5-b4 system; do white players fear this one, or are they eager to see it?

The main line with Ne4 seems really complicated and has a lot of branches, and the engine is recommending all sorts of novelties for white along the way so I'm a bit scared to go for it. Is there a simpler system to play, besides the c6 line (which I don't think is very good)?
