{This is but one of the crucial moments that might have led to a very different outcome in the tiebreaks by giving Harika Dronavalli a chance to turn it around. Black has an easy draw here by repetition. The times were low, but not dramatically so, and both had a few minutes left on their clocks from the initial 10+10 they started with.}
