[February 20, 2018] Updated Opening Line by GM Trajko Nedev:
Gruenfeld Defense, Russian Variation (Hungarian Variation)

[Line 149 : 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. Nf3 Bg7 5. Qb3 dxc4 6. Qxc4 O-O 7. e4 a6]

The Hungarian Variation (7… a6) is the most popular choice among the Grünfeld aficionados against the Russian Variation.

The main line goes 8. Be2 b5 9. Qb3 c5 10. dxc5, where our recommendation for advanced players is 10… Be6 11. Qc2 Nbd7 (which is often seen in top-level games), and for club level players 10… Bb7 11. O-O Nxe4 12. Nxe4 Bxe4.

White has several alternatives on 8th move, but 8. e5 b5 9. Qb3 Nfd7 demands the most serious attention. Here again, White has two interesting options: namely – 10. e6 and 10. h4.

The overall evaluation of Black’s position in this line is pretty much the same like in the remaining lines of the Grünfeld Defense – good, yet quite demanding.
