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
