Now the Russian player comes with a  strong maneuver:
1. c2c4  1... e7e6  2. b1c3  2... d7d5  3. d2d4  3... g8f6  4. c4d5  4... e6d5  5. c1g5  5... c7c6  6. e2e3  6... h7h6  7. g5h4  7... f8e7  8. f1d3  8... f6e4  9. h4g3  9... e4g3  10. h2g3  10... b8d7  11. g1f3 Obvious and natural. 11... d7f6  12. d1c2  12... c8e6  13. e1c1 In a Carlsbad Pawn structure both  players castle long in order to avoid the kingside attack. 13... d8c7  14. c1b1  14... e8c8  15. c3a4 Goryachkina's position seems more pleasant as she  has clear spots to occupy with her knights. At the same time Ju's bishop  pair is idle, but should not be underestimated. 15... c8b8  16. a4c5  Without much hesitation, the world champion decided to get rid of both  white knights. After all, this is presumably one of the advantages of the  bishop pair. 16... e7c5  17. d4c5 In order to free an outpost for her second knight. 17... e6g4  18. d1c1  18... g4f3  19. g2f3  19... d5d4 This is what Ju's plan was all about. She is  trying to build a blockade on the dark squares. 20. e3e4  20... g7g5  21. c2d2 The problem is that the white pawns cannot be easily  stopped. Moreover, the pawn on h6 became an obvious weakness. 21... f6d7  22. f3f4  22... f7f6  23. h1h5 Now that the h6 pawn is practically lost. All Goryachkina needs  is to pile her major pieces against it. 23... g5f4  24. g3f4  24... d7f8  25. f4f5 Limits the knight.
