In the Italian Game: Evans Gambit, Bronstein Defense, white's first move 1.e4 aims to control the center of the board and gain space.

Additionally, e4 frees the way for white's light-squared bishop to be developed. In sum, this move is key to establishing a strong position in the opening and gaining an early advantage.

Black's move 1...e5 is a direct response to white's 1.e4 and aims to take control of the center themselves. By advancing their pawn, black creates symmetry in the position and prepares the way for their bishop and queen to be developed. Moreover, e5 frees up black's king's knight, which can be played to f6 to control the center from a different angle. This move is seen in many popular openings like the Ruy Lopez and the Sicilian Defense and is a classic way to challenge white's control of the board.

White's move 2.Nf3 aims to put pressure on black's e5 pawn and also develops a piece in the process. This move supports white's control of the center by attacking black's pawn and preventing the possibility of black playing d5 in response. Additionally, the knight on f3 can be used to support a future pawn advance to d4, further increasing white's control of the center. By quickly developing a piece, white establishes a strong presence in the opening and positions themselves for a strong game ahead.

White's move 5.c3 aims to attack black's bishop on b4, forcing it to retreat or be captured and allowing white to regain control of the center. This move also prepares to develop white's queen to d3 or e2 and possibly support a future pawn advance to d4, further establishing white's control of the central squares. Additionally, c3 protects white's pawn on d4 in case black later decides to strike in the center with d5. Moreover, by chasing black's bishop back, white gets the opportunity to reroute their own light-squared bishop to a more active square like d3 or e2.

By playing this move, white solidifies their control of the center and prepares the way for a more aggressive kingside attack.

Black's move 6...d6 aims to secure their position by protecting the bishop on c5 and blocking white's pawn advance to e5.
