I've never been able to play well against Bc4 after 1. e4 c5 Nf3 Nc6 Bc4, or even on the second move 1. e4 c5 2. Bc4 (even though e6 is recommended to blunt the bishop). White can play a3 or not to preserve the bishop if d3 is played.
I assume this will eventually be covered in the anti-Sicilian course. What would be the right way for Black to play against it? Always found developing Black's light-squared bishop to then be a problem.
This is why Sicilian structures should be studied as a whole, there is tendency to only examine the particular Sicilian system we play as Black but that is a big mistake. Besides the Fianchetto Structures we have to learn the fundamentals of the Scheveningen Structures, Taimanov/Paulsen Structures, Sveshnikov Structure and by so doing when we get favorable versions of them we know exactly the best plans to adopt and the most effective places for our pieces.
