Now this is wrong. It only pushes the white pieces to better  squares.
1. g1f3  1... d7d5  2. b2b3 Behind in the score Ju decided that her chances would be  better if she avoids the main theoretical lines full of forcing lines. 2... c7c5  3. e2e3  3... a7a6  4. c1b2  4... b8c6  5. d2d4  5... g8f6  6. b1d2  6... c5d4  7. e3d4  7... g7g6  8. a2a3  8... f8g7  9. f1d3  9... f6h5 A good novelty which  enables central play by the second player. 10. g2g3  10... e8g8  11. f3e5  11... c6e5  12. d4e5  12... d5d4  13. f2f4  13... f7f6 Here White manages to consolidate. 14. d1e2  14... f6e5  15. f4e5  15... g7h6  16. e1c1  16... h6e3  17. h1f1  17... c8h3  18. f1f8  18... d8f8 All of this was pretty forced  and with her next prophylactic move Ju moves her king away from the  dangerous diagonal. 19. c1b1  19... b7b5  20. d2f1 Now Goryachkina finds a brave resource. 20... e3g1 For a moment, it seems as the white pieces are stuck, but the world  champion can be amazingly resourceful as well. 21. a3a4 The most  discussed move of the game. And maybe the match. In fact yesterday, when I played my for my Belgium team a very strong GM said he could not believe  his eyes when he saw the move. Neither did his wife who is a world-class  player as well. 21... b5a4  22. b3a4 This is even more weird. Ju completely strips her  king from the pawn cover. Could anyone expect this? A closer look at the  position though reveals that there are some serious advantages behind  White's idea. First and foremost, the light-squared bishop gets an amazing diagonal to work on. 22... f8c8  23. d3c4  23... g8h8 Goryachkina wants to have the g7 square  available for her knight. 24. e5e6  24... h5f6  25. d1d4 This is why the Chinese GM opened the road for her light-squared bishop. She needs the second one there too and the price of  an exchanges seems fair to her. 25... g1d4  26. b2d4  26... c8b7  27. b1a2  27... a8d8  28. d4b2
