Why study this opening?
Black answers 1.e4 with ...c5, controlling d4 from the flank instead of copying ...e5. Different pawn structures give the players different plans; a kingside attack is not automatic.

Plan for White
In the Open Sicilian, White plays d4 and recaptures with a knight after ...cxd4. Develop the remaining pieces and decide where your king belongs before starting a pawn attack. Other choices, including c3 or a quieter setup, lead to different structures.
Plan for Black
After the central exchange, Black has a semi-open c-file: Black’s c-pawn has disappeared, while White’s c-pawn remains. Develop the knights, choose the placement of the bishops and prepare central counterplay. Do not copy a queenside pawn advance if your king is exposed.
Common mistake
When Black plays ...e5 against a knight on d4, notice the attack before making another move. The pawn advance also changes control of d5; decide whether that square can become useful rather than treating every ...e5 as simply good or bad.

An Open Sicilian example
This is one legal example, not a forced sequence or a recommendation against every reply. N means knight, B bishop and O-O kingside castling; the notation below uses international English piece letters.
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be2 e5 7.Nb3 Be7 8.O-O O-O
This example reaches a Najdorf structure with ...a6. After 6...e5 attacks the knight, 7.Nb3 moves it away. Both sides then develop the kingside bishop and castle. The knight already on c3 supports e4. Black’s c-file and the d5-square are strategic questions for later play, not immediate winning threats.
Check your understanding
Whose c-file becomes semi-open after ...cxd4 and Nxd4?
Black’s: its c-pawn has been exchanged, but White still has a pawn on c2.
Why does White move the knight after 6...e5?
The pawn on e5 attacks the knight on d4. In this example Nb3 saves the knight and keeps the game going without a sacrifice.
