Open Sicilian edit

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

They may keep on developing their forces by playing 5...Nc6.
They can choose to strengthen their pawn structure and to reinforce their control of the center with 5...e6.
They can also start to take the control of the queen-side with 5...a6.
They 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.
