Grünfeld Defense: what should White play?

In the classic starting position of the Grünfeld Defense (ECO D80), White's primary theoretical continuation is cxd5, which immediately challenges Black's central presence. Evaluated by engines at +0.31, this exchange enters the Exchange Variation and stands as the most popular choice, chosen in 47.8% of the nearly 7 million games recorded in the database.

Strategic Intent of cxd5

By playing cxd5, White resolves the tension in the center and seeks to construct a broad pawn center. In the main engine line cxd5 Nxd5 e4 Nxc3 bxc3 Bg7, White uses the central pawn majority to claim space while Black prepares to pressure the d4 and c3 pawns from the flank. Across 3.33M recorded games with this move, White achieves an overall score of 49.3%.

Flexible Alternatives with Nf3 and Bf4

Players preferring to delay central liquidation often select Nf3, which occurs in 31.1% of games (2.17M recorded) and holds an engine evaluation of +0.25 alongside a 50.6% White score. An illustrative continuation is Nf3 Bg7 cxd5 Nxd5 e4 Nxc3, transposing back to central structures. Another major path is Bf4, seen in 7.4% of games (515K recorded) with an evaluation of +0.25 and a 50.8% score, where play can proceed via Bf4 Bg7 e3 O-O cxd5 Nxd5.

Positional Outlets with the Bishop

White also frequently explores bishop developments on the queenside without committing to an early capture on d5. The aggressive outpost Bg5 appears in 13.6% of games (948K recorded) with a +0.16 evaluation, often leading into Bg5 Bg7 cxd5 Nxd5 e4 Nxc3 and yielding a 49.9% score for White. Meanwhile, the quieter development Bd2 is evaluated at +0.16 and points toward solid setups such as Bd2 c6 Nf3 Bg7 e3 O-O.
