1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. b1c3  3... f8b4  4. e2e3  4... e8g8  5. g1f3  5... c7c5  6. f1d3  6... c5d4  7. e3d4  7... d7d5  8. c4d5 Now Aronian slightly surprised his opponent with a pawn capture: 8... e6d5 For complete happiness White needs to play both h2-h3 and  0-0. But with the arbiter around he has can chose only one of the two... 9. e1g1  9... c8g4 Here Ding thought that his position is slightly better, but  then he disliked the "unnatural" way that he played. 10. h2h3  10... g4h5  11. g2g4 White wants too much from the position! He not only weakens his kingside but also forces the trade of the opponent's weaker  bishop. 11... h5g6  12. c3e2  12... b8c6  13. c1g5  13... f8e8  14. d3g6  14... h7g6  15. a1c1  15... d8d7 Aronian is clearly better. He can use the  central light-squared outposts to plant pieces close to the opponent's  king as there is no light-squared bishop to cover them. Or Black may also  chose to put pressure on the isolated white pawn as his bishop can hit it.  16. g5f6  16... g7f6  17. d1d3  17... e8e4  18. e2g3  18... e4e7 A surprising retreat for the  first player. And a relief. 19. a2a3  19... b4d6  20. f1e1  20... e7e1  21. c1e1 "After the trade of the rooks my position is  still worse, but not as much."
