1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... a7a6  4. b5a4  4... g8f6  5. e1g1  5... f8e7  6. a4c6  6... d7c6  7. d2d3  7... e7d6  8. b1d2  8... c8e6 One of the most solid set-ups for Black in this line. You can call it aggressively-solid, as Black often intends to castle long and  start kingside expansion. 9. d2b3 A novelty which, in its turn,  intends a speedy attack against the enemy's queenside. 9... d8e7  10. b3a5  10... e8c8 Ding is not worried about White's attack. \"I  did not expect long castle. I should have, of course, it's a very  reasonable way of playing.\" (Giri) 11. d1e2 The queen side-steps the  X-raying of the enemy rook and the eventual discovered attacks. \"I am not sure if this is necessary.\" (Giri) 11... e6g4  12. c2c3  12... c6c5  13. a2a3 Now Ding finds a brilliant way to calm his opponent's  queenside ambitions. 13... c7c6 \"I was very surprised/confused/impressed (in this  particular order) with c7-c6\" (Giri) 14. b2b4  14... d6c7  15. a5b3 The pressure  against the c5 pawn is an illusion. White is hoping for a3-a4 and then  b4-b5. 15... f6d7 Now Ding stabilizes his queenside and launches a strong  kingside attack. 16. h2h3  16... g4h5  17. c1e3  17... f7f5 A very strong move. The pawn  is not as important as the open files and diagonals for the black pieces. 18. e3c5  18... e7f7  19. a1b1 \"and I think Black has all the trumps here\"  (Giri) 19... g7g5 \"A little overambitious.\" (Giri) 20. e4f5  20... g5g4 Only this is a mistake based on an oversight. 21. f3g5  21... f7f5  22. h3h4 \"He missed this thing. \"From here it was nice.  You might think it was sort of a straightforward game but it really  wasn't.\" (Giri) 22... b7b6 \"A small trap.\" (Giri) 23. g5e4 \"It's one of those cases where you feel like you have at  least practical compensation [for the piece] but at these days usually  when you feel you have practical compensation it's also objectively  winning somehow.\" (Giri) 23... b6c5  24. b4c5 \"It's so easy to play and my king is so much  safer.\" (Giri) 24... d7f6  25. e4d6  25... c7d6  26. c5d6  26... d8d6  27. d3d4 Again this move. Once that the queen gets  involved it is all over. 27... c6c5  28. b3c5  28... h8e8
