By establishing an early pawn presence in the center, White puts immediate pressure on Black, forcing them to respond and limiting their options. Furthermore, e4 allows White's bishop on f1 to be developed and the knight on g1 to be brought out. This move sets the stage for White to potentially launch a powerful attack on Black's position.

When Black plays e5 in response to e4 by White, they similarly aim to control the center and gain space for their own pieces. By advancing the pawn to e5, Black challenges White's central control, aiming to establish their own share of the board. Additionally, e5 opens up the position, allowing Black's pieces to emerge and exert pressure on the White position. This move is a standard response to White's opening move, enabling Black to fight for control of the board and develop their pieces actively.

When White plays Nf3 in response to Black's e5, they continue their development while maintaining pressure on Black's central pawn. The knight also has the added benefit of controlling key squares and potentially supporting an attack on Black's position.

Additionally, Nc6 allows Black to castle kingside and connect their rooks. This move is a flexible and sensible option for Black, with the potential for tactical possibilities down the road.

When White plays c3 in response to Black's Nc6, they aim to counteract any potential threat from Black's pawn on d5 while preparing to defend their pawn on d4. The move c3 also supports White's center and lays the groundwork for d4, opening up the option of a pawn break later on. Additionally, c3 frees up the queen's knight on b1 to be developed and supports the control of the d4 square.

The move f5 also prepares to develop Black's pieces, particularly the bishop on c8 and the knight on f6. Additionally, f5 can lead to pawn exchanges, potentially weakening White's pawn structure or opening up lines of attack for Black. However, the move also has downsides, such as exposing the e5 pawn to attacks and creating potential targets for White's pieces. In sum, f5 is a sharp and aggressive option for Black, creating complications and opportunities for tactical maneuvers.

The move d6 also allows Black's dark-squared bishop to be developed and supports the control of the central squares. Additionally, d6 can prepare for a pawn break with c5, putting pressure on White's central pawns. However, d6 also has downsides, such as potentially restricting Black's queen and bishop on the c8-h3 diagonal, and potentially rendering their knight on f6 stationary.
