Neo-Gruenfeld Defense, Original Defense

[Line 131 : 1. d4 Nf6 2. c4 g6 3. Nf3 Bg7 4. g3 c6]

After the usual 5. O-O d5, apart from the Delayed Exchange Variation (6. cxd5), covered in our Line 132, there are other options that are popular among the top level players.

Defending the c-pawn with 6. Qb3 is often followed by pressing on d5, with Nc3 and Ne5. The game frequently continues 6… O-O 7. O-O, and now both 7… dxc4 and 7… Qb6 lead to balanced positions, while 7… a5 is an interesting alternative.

White can leave the c-pawn unprotected by playing 6. O-O, where 6… dxc4 is a viable alternative to the more common 6… O-O. White regains the pawn after 6… dxc4 7. a4 O-O 8. Na3, but Black gets an active piece play.

Modern line 6. O-O O-O 7. Nbd2 leads to a quiet game, where White’s plan is the queenside fianchetto, while Black generally counters it with Bf5, a7-a5-a4 and Ne4.
