Grünfeld Defense: Exchange Variation
1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5
The Exchange Variation of the Gruenfeld is considered one of White's most critical attempts. Since the d5 pawn is not defended by another pawn, White is able to capture it and remove Black's central pawn, leaving White able to build a strong pawn center, which Black tries to pressure with pieces.
Pros:
- White builds a big center
- White might get attacking chances
Cons:
- It can be hard to maintain White's center
- Black will get active piece play
- Black can get counterplay on the queenside
