slow down White's Queen side initiative which usually comes

{ The 2.Nc3 of the Closed Sicilian introduces a slower way of building up. Rather than breaking Black's grip on d4 with a quick d2-d4, White plays 2.Nc3 followed by fianchettoing the king bishop, sometimes with a slow attack on the kingside in mind.

Pros:

Avoids the heavy theory of the Open Sicilian
Leads to a slower, strategic type of play, undesirable for many Sicilian players
Cons:

Allows Black to develop his pieces comfortably
Gives Black a good plan of attack with ...b5
Leaves Black with good control of the d4 square } 1. e4 c5 ( 1... e6 ) 2. Nc3 { The 2.Nc3 of the Closed Sicilian introduces a slower way of building up.
