White plays c4 after Black's d5 to further control the center of the board and attack Black's pawn on d5. c4 also clears the way for White's light-squared bishop to be developed and puts pressure on Black's position. By playing c4, White is gaining space and creating possibilities for their pieces to be optimally placed.

In the Queen's Gambit Accepted: Classical Defense, Russian Gambit, Black chooses to take White's pawn on c4 with their own pawn, dxc4, to lure White into playing the gambit. By accepting the gambit, Black temporarily sacrifices material in exchange for gaining the initiative. This move creates an imbalance in the game that allows Black to seize control of the center and develop their pieces quicker. Taking the pawn on c4 also opens up new diagonal lines for Black's light-squared bishop, which can prove useful in Black's future attacks. In essence, dxc4 is a bold move by Black that aims to exploit the weaknesses in White's position.

White plays e3 after Black captures their pawn on c4 with dxc4. This move solidifies White's control over the center and provides additional support for the d4 pawn. Moreover, e3 prepares for the development of White's light-squared bishop to e2, where it can be utilized effectively. The move also hinders Black's plan of pushing their pawn to e5 by placing additional pressure on the d5 pawn. The e3 pawn also frees up White's queen, which can now be positioned on a better square and serve a greater purpose in the game. Ultimately, e3 is a strategic move that strengthens White's position and provides a solid foundation for future developments.

After White's e3 move, Black develops their knight to f6 to pressure White's pawn on e4. Moreover, the knight on f6 controls the d5 square, which can help to hinder White's central control. Additionally, Nf6 prepares for Black's future bishop development to b4 or g4, where it can successfully target White's weak points.

Moreover, castling kingside sets the king on a safer square and hinders Black's plan of attacking White's king on the kingside. The move also frees up the knight on f1 to be developed to other more useful squares. Furthermore, castling kingside enables White to initiate additional attacks on the queenside or center of the board. Castling is a crucial move that is included in almost every opening and in this case, is an important move for White to stabilize their position and maintain balance in the game.
