Closed Sicilian (Main line): 1.e4 c5 2.Nc3 Nc6 3.g3 g6 4.Bg2 Bg7 5.d3 d6
2.Nc3 is White's second most common move responding to 1.e4 c5. Black's options are similar to those for 2.Nf3, the most common being ...Nc6, along with ...e6 and ...d6, and less commonly ...a6 and ...g6. In all cases, White can then play 3.Nf3, as if White had played 2.Nf3 then 3.Nc3 (e.g. 2.Nf3 Nc6 3.Nc3, B30).
For the most part, other moves are the Closed Sicilian. Possible moves are 3.g3 and 3.f4 in general, also 3.Nge2, and less commonly 3.d3 and 3.Bc4. Some lines may transpose to the Open Sicilian, but there are many that do not.
Also of some interest is 3.Bb5 to ...Nc6.
A typical line is 2...Nc6 3.g3 (ECO code B24). Also 2...Nc6 3.f4 is the Closed Sicilian, Grand Prix Attack (part of B23).
White can also keep their options open with 3.Nge2. Andrew Soltis has dubbed that the "Chameleon System", since White maintains the option of playing a Closed Sicilian with 4.g3 or transposing to a standard Open Sicilian with 4.d4 cxd4 5.Nxd4. Two drawbacks are that (a) the Closed Sicilian lines with an early Nge2 are not very challenging for Black, and (b) if Black plays 2...Nc6 3.Nge2 g6, 4.d4 reaches an Accelerated Dragon where White has lost the option of playing c4, the Maróczy Bind, often considered White's best line.[45] In view of possible transpositions to the main Sicilian variations, Black's reply to 2.Nc3 will depend on what they play in the Open Sicilian. 2...Nc6 is the most common choice, but 2...e6 and 2...d6 are often played. The Main line of the Closed Sicilian is 2.Nc3 Nc6 3.g3 g6 4.Bg2 Bg7 5.d3 d6 (diagram), when White's main options are 6.Be3 followed by Qd2 and possibly 0-0-0, and 6.f4 followed by Nf3 and 0-0.
