Create a free account →The idea: give White the center, then attack it
After 3...d5, Black is inviting White to grab space with cxd5 and e4 — and then spending the rest of the game proving that big center is a target, not a strength. The fianchettoed bishop on g7 becomes a sniper on the long diagonal, pointing straight at the heart of White's structure. Stockfish rates the position +0.41 for White at depth 16, and the best continuation starts with Nf3 Bg7 cxd5 Nxd5 — Black recaptures with the knight, not the pawn, to keep the diagonal open.
What White will play against you
Across 1,725,216 games, four systems stand out:
- cxd5 (Exchange Variation) — the most played (493,012 games) but White's weakest try: just 44.7%. The Exchange gives Black exactly the structure the Grünfeld wants.
- Nf3 — flexible and second-most popular (410,546 games, White 47.8%), delaying the center commitment.
- Bg5 — pins the knight immediately (283,575 games, White 48.6%).
- e3 — the cautious approach (237,389 games, White 45.2%).
The pattern is striking: White's most natural aggressive tries score worse. Only Bg5 and Nf3 approach 48%.
How to play as Black
When White plays cxd5 (the most common), recapture with ...Nxd5 — not the pawn — to keep the g7 bishop's diagonal intact. The Stockfish PV from the diagram confirms this: Nf3 Bg7 cxd5 Nxd5. Against Nf3 or Bg5, first get your bishop to g7 and castle before entering the central fight. The key plan in almost every line: castle kingside, activate the rook on f8, then push ...c5 or ...e5 to crack White's center. The g7 bishop does its best work when the center is open.

If you're looking for a Black opening where the numbers confirm the theory, this is it.

Why does 3...d5 give up the center?
