Chess players must always consider their opening strategy to dominate their opponent from the first moves. When playing with White, the move e4 is a popular choice to create an open game and control the center squares.

By controlling the center, White can create tactical opportunities and threaten to attack Black's position from different angles. In sum, e4 is a critical move for creating a solid opening.

When playing with Black, the move e6 is a popular choice to control the d5 square and resist White's central pawn push. By controlling this square, Black can slow down White's pawn advance and prevent a strong pawn center. Additionally, e6 prepares the way for Black's light-squared bishop to develop and control the diagonal a2-g8. This move is a solid option and can lead to different variations depending on White's response. In sum, e6 is a crucial move to balance Black's position and prevent a strong White center.

Playing d4 is a classic approach by White to control the center and challenge Black's pawn on e6. This move creates a pawn chain with e4 and d4 pawns and attacks Black's center. White is also preparing to develop the queen's knight and apply more pressure on the d5 square. Moreover, this move allows White to gain space on the board and restrict Black's piece activity. However, playing d4 can also lead to tactical and positional complexity, as Black has different options to respond, such as exchanging on d4 or keeping the tension in the center.
