3 players, one crown: How can India's Vaishali win Women's Candidates at eleventh hour?

In the running for the title, there are three contenders: India’s Vaishali Rameshbabu, Kazakhstan's Bibisara Assaubayeva, and China’s Zhu Jiner. Vaishali and Bibisara currently lead with 7.5/13 points, followed by Jiner on 7/13. The math is simple yet somewhat disquieting. If Vaishali and Bibisara both win their final games, they head into a tie-break on Thursday.
