1. g1f3  1... d7d5  2. g2g3  2... g8f6  3. f1g2  3... c7c5  4. e1g1  4... e7e6  5. c2c4  5... d5d4  6. e2e3  6... b8c6  7. e3d4  7... c5d4  8. d2d3 This position can arise from many different move orders. Here Black has a wide choice: he can develop the bishop on e7, d6, c5, or he can play the prophylactic 8...h6 first, preventing plans with Bg5 or Ng5 by White. 8... f8d6 Ding chooses the most popular move. 9. b1d2 [%c_effect d2;square;d2;type;Interesting;persistent;true] As is usually the case, Carlsen has his own views on openings. He is a creator, not a follower. 9... e8g8  10. f3g5 [%c_effect g5;square;g5;type;Interesting;persistent;true] A typical move in this pawn structure. The knight can go to e4, and White opens the path for the advance of the f-pawn, gaining space on the kingside. 10... d6e7 Anticipating the knight's jump to e4. 11. f2f4 This is one of the ideas of White's previous move. 11... a8b8 A novelty. Ding wants to counterattack on the queenside with Qc7 and b7-b5. 12. d1e2  12... d8c7  13. g3g4 Carlsen shows he is in an aggressive mood. 13... b7b5  14. b2b3 A good choice, simply protecting the c4-pawn.
