The move 2. c4 by White is known as the Queen's Gambit, a popular opening that aims to further consolidate White's central control. By pushing the pawn to c4, White releases their c1 bishop and puts pressure on Black's d5 pawn. If Black were to capture the pawn on c4, White would recapture with the bishop and further enhance their center control. Additionally, the pawn on c4 adds pressure against Black's center and can lead to tactical opportunities later in the game. In sum, this move helps White to gain space and control over the center of the board.

In the Slav Defense: Steiner Variation, the move 2...c6 is a common response by Black to White's Queen's Gambit.

In sum, this move solidifies Black's control over the central squares and prepares for future piece development. The Steiner Variation diverges from the main line of the Slav Defense, as Black's pawn on c6 can block the natural development of their bishop.

In sum, this move is a versatile option for White that adds more options and flexibility to their position.

By capturing White's pawn on c4 with their own pawn, Black creates a central pawn majority and gains more space on the board.

In sum, this move is a dynamic option for Black that sets the stage for further piece development and strategic play.

The move 5. a4 by White is a common response to Black's dxc4 in the Slav Defense.
