By occupying the center, White creates pressure on Black's position and restricts the movement of their pieces. This move sets the stage for an aggressive, attacking game plan.

In response to 1. d4, Black plays d5 to counter White's attempt to control the center. This move also helps to establish Black's own pawn on a strong central square and prepares for the activation of Black's pieces.

Moreover, the move creates a pawn on e4 which can act as a central wedge in Black's position, giving control over the d5 and f5 squares. However, by having a pawn on e4, Black also opens up the possibility of it coming under attack, forcing Black to devote resources to defending it. Despite this, dxe4 is a common move for Black to play in the Bogoljubov Defense and can lead to exciting and dynamic positions.
