1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. b1c3  3... f8b4 The Nimzo-Indian had always had solid  reputation. 4. d1c2  4... d7d5 But this is a surprise. So far Ju has always  played either: 5. a2a3  5... b4c3  6. c2c3  6... f6e4  7. c3c2  7... c7c5  8. d4c5  8... b8c6  9. g1f3  9... d8a5  10. c1d2  10... e4d2  11. c2d2  11... d5c4  12. d2a5  12... c6a5  13. e2e3  13... b7b5  14. c5b6  14... a7b6 A solid, sound  novelty. Black needs to hold in the last two games to triumph with the  title and Ju plays the opening very safe. 15. f3d2  15... b6b5  16. a3a4 Tan has to trade more pawns as otherwise there is a serious risk  that her bishop remains workless on the f1-a6 diagonal. 16... a5b7  17. a1a3  17... a8a4  18. a3a4  18... b5a4  19. f1c4  19... c8d7 The opening outcome is perfect for  Black. Ju's only weakness can be easily defended by both the knight and  the bishop, whereas the pawn on b2 does not look great at the moment. 20. d2e4  20... e8e7  21. e1e2  21... h8b8 Hitting the weakness on b2. 22. h1b1  22... d7c6  23. e4c3  23... b7c5 Black managed to arrange her pieces optimally and stands even slightly better. She can now search for weaknesses on the wing where she  is stronger--the kingside. 24. f2f3  24... f7f5  25. e2d2
