As long as you keep an eye on b6 square there wont be any problem.
Sicilian Katalimov
Well, it's not bad for white, it allows him to control the center. It's just a more closed position were in this cases need more accurate development. I don't know how black should proceed, suddenly nothing makes sense.
Depence from who is playing white pieces! It's not accident that is not popular in the higher levels.
