White plays c4 in response to Nf6 to gain even more control over the center and further develop their pieces. This move also prepares the way for white's queen's bishop to come out and for the queen to control the c-file. By advancing the pawn to c4, white restricts the movement of black's knight on b8, which can no longer go to its most natural square c6. Additionally, c4 supports white's d4-pawn and puts pressure on black's position, forcing them to be precise in their responses.
