1. e2e4  1... e7e5  2. f1c4 The Bishop opening is often used to avoid the Petroff  Defense. 2... g8f6  3. d2d3  3... c7c6  4. g1f3  4... d7d5  5. c4b3  5... a7a5  6. a2a4  6... f8b4 One of the good continuations for Black. Ju deprives the  opponent's knight of the c3 square. 7. c2c3  7... b4d6  8. e1g1  8... e8g8  9. e4d5  9... c6d5  10. b1a3  10... b8d7  11. f1e1  11... h7h6 Now the Bc1 feels uncomfortable. 12. a3b5  12... d6b8  13. d3d4 Sooner or later White will have to fight for the center. 13... e5e4  14. f3d2  14... d7b6  15. f2f3 The point behind Tan's 13.d3-d4.  However, it turns out that Black's center is more stable than it seems. 15... f8e8  16. b3c2  16... c8d7 Super-calm and very good. 17. a1b1  17... e4f3  18. d2f3  18... f6e4  19. f3e5 Not happy with the outcome of the opening, Tan  decided to sacrifice a pawn. 19... b8e5  20. d4e5  20... d7b5 Subtle. 21. a4b5  21... e8e5  22. c1e3  22... e5e6  23. e3d4 The dark-squared white bishop is an excellent piece,  but Black's knights are great as well. Ju finds a way to bring them into  their optimal squares. All in all, the compensation for the pawn is  insufficient. 23... b6c4  24. c2d3  24... d8g5  25. b2b3  25... c4d6  26. b1b2  26... a8e8  27. b2e2  27... d6f5 Black's maneuvers were more usefuk than White's. She is  close to winning.
