Open Sicilian[edit]

Time has come for Black to make an important strategic choice.

He may keep on developing his forces by playing 5...Nc6.
He can choose to strengthen his pawn structure and to reinforce his control of the center with 5...e6.
He can also start to take the control of the queen-side with 5...a6.
He may decide to put a deadly bishop in g7 and play 5...g6.

These are the four main variations. Another more aggressive option is 5...e5, less popular than the previous moves.
