1. g1f3  1... g8f6  2. c2c4  2... c7c5  3. b1c3  3... d7d5  4. c4d5  4... f6d5  5. e2e3  5... e7e6  6. f1c4  6... f8e7 An achievement for Grischuk. He deprived his opponent of his  Gruenfeld bishop. 7. e1g1  7... e8g8  8. d1e2  8... b8c6  9. f1d1  9... b7b6  10. d2d4  10... d5c3  11. b2c3  11... d8c7  12. e3e4  12... f8d8 A position similar to the Queen's  Indian Defense came on the board. The plans remain the same as in the  Gruenfeld though: White would try to make use of his superior center and  more space to attack on the kingside, while Blackwould be looking for  counterplay on the opposite wing and eventual trades on the open files. 13. c1e3  13... c6a5  14. c4d3  14... c8b7  15. h2h4 Again, a very typical move against the  Gruenfeld where White is ready to hit the enemy fianchettoe with h4-h5.  But here too, it helps the attack as it prepares Nf3-g5. 15... b6b5  Vachier-Lagrave uses the first possibility to free himself. 16. d3b5  16... b7e4  17. d4c5  17... e4f3  18. e2f3  18... e7c5  19. e3f4 This additional possibility was not here had  Black had taken on c5 first.
