\"Very bad, but I couldn't find a move,\" said Wang as this  weakens the kingside too much. But what was Black's choice?
1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. g1f3  3... d7d5  4. g2g3 Giri's exceptional technique naturally leads him to the Catalan, an opening with which the Dutch GM achieves  excellent results, consistently. 4... f8e7  5. f1g2  5... e8g8  6. e1g1  6... d5c4  7. d1c2  7... a7a6  8. a2a4 The latest trend in the Catalan. 8... c8d7  9. c2c4  9... d7c6  10. c1f4  10... e7d6  11. b1c3 Since White's play is related to kingside expansion he does not  object to the opening of the g-file. 11... d6f4  12. g3f4  12... a6a5 Wang needs to fix some squares for his pieces on the queenside. 13. e2e3  13... b8a6  14. f3e5  14... c6g2  15. g1g2  15... c7c6  16. h2h3 Only this is a novelty. White prepares a shelter for his king on h2, and once that  the king is hidden he will not have to worry about the possible checks on  the long diagonal. 16... d8b6  17. c4e2  17... c6c5 Wang decided to solve all his problems once and  for all, but this seems a tad premature. 18. f1d1 Keeping the tension. 18... c5d4  19. d1d4  19... a8d8  20. d4d8 A moment of hesitation for Giri and the best  continuation! 20... b6d8 A sad necessity. 21. a1d1  21... d8a8 Black sometimes solves his problems with ambushes like this,  but here it does not work. 22. g2g1 It's interesting that the Dutchman  did not use the shelter. 22... a6b4  23. e2b5 White dominates. Ne5-c4 is a powerful threat, but the  infiltration of the rook along the d-file is equally scary for the Chinese GM. Therefore he blocks the open file: 23... b4d5  24. c3d5  24... f6d5 But  Giri finds an even better one. 25. d1c1  25... h7h6  26. b5d7  26... d5f6 Black's position is very unpleasant to play and no wonder Wang commits a mistake soon. 27. d7d6
