In my experience, a lot of beginners tend to do a Maroczy bind with 2.c4 which I don't think is particularly sound.
That's funny. One of these days you'll run into someone who knows how to play the Bind well and you'll change that assessment. The slow crush of a well executed Maroczy Bind is uniquely unsettling because you feel completely helpless. You see it coming but you can't do anything about it except watch and wait. I've played enough of those games that I think it's unwise for black to allow the Bind at all (without thorough preparation.)
I echo gonnosuke, invite the Maroczy Bind at your peril:
I love getting into this variation of the Sicilian
I should have started a thread where I have a great Bishop sacrifice on e6 for three pawns and the initiative. I then return a pawn to win a crushing amount of material, it's great! Check it out sometime.
Shameless self-plug aside, the Sicilian is a theoretical beast that I've treaded for far too long without a map.
