She threw the last game (in just five moves, which takes some skill in and of itself) to protest the fact that 7 of her 10 opponents had been female. I was kind of sympathetic to the organizer's statement that pairings are random, until he went Full Condescension:

But she's also the women's world champion and of course that brings responsibilities with it. Perhaps when she reflects she will think 'maybe I could have handled this in a slightly different way'.

I think we're listening to what she's saying about the pairings, I think that we're sympathetic to what she is saying about the pairings. I don't think that the pairings are wrong, I think that they’re a reason for concern from her perspective.

I hope that she will come back and play again and that these sort of, what I call bad days at the office, don't occur too frequently.

But I'm sorry for Yifan, because I think she has let herself down at little bit today.
