The Sämisch Variation of the Nimzo-Indian arises after White plays 4.e3 followed by 5.a3, challenging Black's bishop on b4. By capturing on c3, Black doubles White's c-pawns but concedes the bishop pair. The characteristic feature of this line is White’s commitment to a solid, flexible pawn structure with an emphasis on controlling the center with pawns on d4 and c4, supported by e3 and c3.
From White’s perspective, this variation is generally positional and solid, aiming to maintain a strong center and leveraging the bishop pair later in the game. It is somewhat defensive early on but with long-term attacking potential. Black, on the other hand, takes on a more strategic and counterattacking stance, seeking to undermine White’s center and exploit the doubled c-pawns.
Regarding the center, both sides focus heavily on central control: White occupies the center with pawns on d4 and c4, while Black aims to challenge and pressure this center from a distance. Thus, this opening involves a significant battle for central dominance.
