Moves: 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. Nf3 Bg7 5. e3 O-O 6. cxd5 Nxd5

Description: This variation of the Grünfeld Defense features White playing 5.e3, a more solid and restrained approach than the more common 5.Qb3 or 5.cxd5 early on. By playing 6.cxd5, White exchanges pawns in the center, challenging Black’s stronghold on d5 and aiming to reduce Black’s central counterplay. Black recaptures with the knight, maintaining active piece play and pressure on the center.

Characteristic: The move 5.e3 supports White’s central pawns and prepares for natural development of the light-squared bishop, often aiming for a solid but flexible setup. The exchange on d5 clarifies the central tension early, signaling a balanced but dynamic middlegame.

Attacking or Defensive: For White, this line is generally more positional and solid rather than outright attacking, focusing on controlling the center and careful development. Black, meanwhile, plays actively, seeking counterplay by pressuring White’s center and using piece activity. Thus, White adopts a somewhat defensive stance aiming for central control, while Black looks for active counterattacks.

Center Control: Yes, this opening directly contests the center. White’s 6.cxd5 challenges Black’s central pawn on d5, and Black’s knight recapture keeps the center dynamic. Control and contest over the central squares is the main theme of this variation.
