The opening is characterized by White's fianchetto of the light-squared bishop and the early central pawn exchange, leading to an asymmetrical pawn structure. White aims to regain the pawn on c4 and establish a strong pawn center with pawns on d4 and e4, while Black tries to challenge White's pawn structure and central control with moves like c5 and Nc6.

In this line, Black's light-squared bishop is often developed to e7, allowing for the possibility of castling kingside. White's knight on f3 and bishop on g2 work together to control the central squares, while Black's knight on f6 and pawn on e6 help to contest the center.

The opening can lead to various pawn structures, such as the hanging pawns, isolated queen's pawn, or symmetrical pawn structures, depending on how the game unfolds. Both sides have chances for active piece play and tactics, as well as strategic plans revolving around the pawn structure.

White often aims for a central break with e4 or d5, while Black looks for counterplay on the queenside or in the center. Proper understanding of the resulting pawn structures and piece coordination is crucial for both sides in this opening.

Overall, the opening offers a rich and complex middlegame with chances for both sides to outplay their opponent, making it a popular choice for players of all levels.
