1. d4 Nf6 2. c4 g6 3. Nc3 d5

After 1. d4 Nf6 2. c4 g6 3. Nc3 d5, which variation of the Grunfeld Defense leads to the most solid and strategic position? If possible, I prefer a variation with possibilities for a minority attack. The Exchange Variation (4. cxd5) is too sharp and contains too much theory. If possible, there should not be loads of theory.

Maybe 4.e3 is an interesting idea against the Grünfeld. Usually, black answers with 4....Bg7, but it should be noted that black can transpose to the Slav defence with 4....c6.

After 4....Bg7, white has two interesting options: 5.Qb3 and 5.cxd5.

  • 5.Qb3 is probably the most popular continuation, attacking the pawn on d5. If black plays 5....dxc4, then white should be slightly better after 6.Bxc4. After 5....c6, a Slav defence-like position arises, which black players probably want to avoid. Therefore, 5....e6 is the most common response. Then, white can (temporarily) stop black from castling with the interesting move 6.Qa3!?, which has been played by several strong grandmaster like Nakamura (against Caruana), Ivanchuk and Dreev. After 6....Qe7?!, white obtains a clear advantage after 7.Qxe7+ Kxe7 8.b3.
  • The idea behind 5.cxd5 is to answer 5....Nxd5 6.Nxd5 Qxd5 with 7.Ne2 and 8.Nc3. This line has been played by several grandmasters, including Kramnik (in a rapid game against Svidler) and Andreikin.

Although my suggestion has some ideas and has been played by many grandmasters, it is far from the most principled continuation against the Grünfeld. Nevertheless, I believe it has some venom and could be a good try to surprise your opponents.

Bg5 on move 4 is a strategic move, prioritising a minority attack in some lines. The line 6.cxd5 with this plan is covered in Richard Palliser's Play 1.d4! Also 6.Bf4 is possible, see the game below played between Shogi legend Yoshiharu Habu and super GM Maxime Vachier-Lagrave (Annotations by Maxime Vachier-Lagrave).

  • I like the suggestion of Bg5, I wonder if it is better to play 4.Nf3 Bg7 5.Bg5 or 4.Bg5 immediately? What are the differences? – Maxwell86 Aug 16 '15 at 10:05
  • I don't think there is much of a difference. Black wants to play 4...Bg7 after either move. – magd Aug 16 '15 at 10:20
  • After 4.Bg5, 4....Ne4 is also a popular move. In this case, white cannot take on d5. Furthermove, after 4....Bg7, white can play 5.Bxf6. – Maxwell86 Aug 16 '15 at 10:37
