Anti-Grunfeld System
1.c4 Nf6 2.Nc3 g6 3.e4 d6 4.d4 Bg7 5.Nf3 0-0 6.Be2
White builds a broad center against a kingside fianchetto and aims to avoid main Grunfeld theory. The structure gives White space, while Black counters with dynamic piece pressure.

Center vs piece pressure
Strategic Ideas
- Space advantage: White's center can control key squares and restrict Black.
- Counterstrike readiness: Black often targets the center with ...e5 and ...c5.
- Development race: White should castle and coordinate quickly.
- Piece placement: Knights and bishops should support central stability.
- Flexible transition: Structures can transpose to favorable King's Indian types.
Main Continuations
Mainline Counter
...e5 7.0-0 Nc6 8.d5 Ne7

Slow Build
...Nbd7 7.0-0 e5 8.Be3
Both sides improve pieces before committing to pawn breaks.
Typical Plans
For White
- Maintain space: Keep the center stable and expand on the kingside when ready.
- Piece routes: Nd2-c4 and Be3 are common improvement plans.
- Prepare breaks: f3/f4 can support controlled attacking play.
For Black
- Undermine center: Use ...c6, ...cxd5, or ...f5 ideas based on setup.
- Piece activity: Knights should seek c5 and e5 squares.
- Dynamic balance: Counterplay matters more than static solidity.
Common Mistakes
White: Overextending without support can make the center a tactical target.
Black: Passive setups allow White to consolidate and press long-term.
