Nimzo-Larsen Attack: Symmetrical Variation

A flexible and offbeat opening, it allows for various pawn structures and can lead to rich middlegame positions.

The opening is characterized by the fianchetto of both the light-squared bishops for White and Black, with the aim of controlling the central squares from the sides. It is a relatively rare and unorthodox opening, often employed by players who prefer to avoid mainstream opening theory and catch their opponents off guard. The opening can lead to a variety of pawn structures, ranging from symmetrical to highly imbalanced, depending on how both players choose to develop their pieces.

In the early stages of the game, both players have the option to transpose into other openings, such as the English Opening or the Queen's Indian Defense. This flexibility can be an advantage for the player who is more familiar with the resulting positions and plans. The opening can also lead to rich middlegame positions, with chances for both sides to create imbalances and exploit weaknesses in the opponent's camp.

While not as popular or theoretically explored as other openings, it has been employed by several strong grandmasters, including former World Champion Anatoly Karpov and Danish Grandmaster Bent Larsen, who lent his name to the opening. Players who enjoy unconventional and flexible positions may find this opening a suitable weapon in their repertoire.
