23. Re4. It is just the case to note that 23. b4! seems much stronger, as after 23. ... Bf6 24. b5 White’s passed Pawn would nail down Black’s weaknesses.

“Black’s pieces appear to be reliably protecting each other. Is that so?”.

Notes by GM Sergei Yuryevich Shipov for the daily bulletin (http://istanbul2012.tsf.org.tr/en/reviews/261-day-9-the-fall-of-the-giants.html):
The whole game Elmira was fighting as a lioness that protects her baby-lions. But the power left her after the time control.
41...Kh5?
Horrible blunder. Accurate move 41...Ra2! kept a big intrigue. Yifan would have to work a lot to win. In the analyses I did not at all find a way to win for White. Perhaps, because there is not. Black threatens the rook escapade to a1, and the exchange sac on c7 is far not that perspective as it may seem.
42.Rxc7! Qxc7 43.Qd1+! and on 43...Kh6 follows 44.Qc1+ winning the rook...nothing to do but resign.
