How to counter the Sicilian Defense: O'Kelly Variation, Maróczy Bind, Geller Line

In general, it is crucial to maintain control over the center to have maximum chances to succeed. Playing precise moves with the aim to apply pressure on the d4 pawn and gain space on the board could help to neutralize Black's position.

Pawn structure in the Sicilian Defense: O'Kelly Variation, Maróczy Bind, Geller Line

Another critical point is that Black should be careful not to create pawn weaknesses, since this would expose their position to a potential attack.

In the Geller Line, after the moves 5...e5 and 6.Nc2 Ng8, Black's pawns can become overextended, and their position can appear cramped. However, this pawn structure allows Black to create critical pressure against White's center and break up their pawn chain.
