Black's pawn structure is solid and can support various pawn breaks, while White has more space and can choose between different plans. This opening is a good choice for players who enjoy a flexible and solid opening with chances for counterplay.

It is important for both sides to be familiar with the typical plans and ideas in this opening, as the middlegame can become quite sharp and double-edged. Knowledge of the key move sequences and an understanding of the resulting positions will be crucial for success in this opening.
