d4

-0.26

The move 3.d4 by White is a classical response in the Sicilian Defense opening. By advancing the d-pawn, White aims to take control of the center, create some space for the queen and bishop and open the lines for future development. This move also puts pressure on Black's pawn on c5, which is now attacked twice, so Black must either defend it or capture the d-pawn. If Black captures with the pawn, White can recapture with the queen, further developing that piece while also opening up a potential skewer or discovered attack on Black's queen. In sum, the move d4 is a bold attempt by White to take control of the game's tempo and accelerate piece development.

cxd4

+0.38

The move 3...cxd4 by Black is a logical response to White's advance with d4. By capturing the central pawn, Black not only fights for control of the center but also frees up their position, allowing for easier piece development. This move also puts immediate pressure on White's queen, which must recapture the pawn or move away. If White recaptures with the queen, it could then be vulnerable to potential harassment by Black's minor pieces. Capturing with the knight would discourage Black's knight from developing to c6 but would also potentially block in White's bishop on c1. In sum, the move cxd4 opens up a number of possibilities for Black, both in terms of central control and creating opportunities for piece activity.

Qxd4

-0.19

In the Sicilian Defense: O'Kelly Variation, Normal System, Zagorovsky Line, the move 4.Qxd4 by White is a natural response to Black's capture with cxd4. By capturing the pawn with the queen, White both develops the queen and increases the pressure on Black's position. This move also threatens a potential discovered attack if Black decides to develop the knight to c6 or e6. However, placing the queen on d4 early can be a risky move, as the queen can be vulnerable to attack and potentially get trapped in the center. Black can take advantage of the queen's early development to create threats against it and gain a positional advantage. In sum, the move Qxd4 reflects White's willingness to take risks and attempt to maintain an aggressive position early in the game.

Pawn structure in the Sicilian Defense: O'Kelly Variation, Normal System, Zagorovsky Line
