And again, one where challenger Humpy Koneru had the better chances, despite playing Black. Or maybe because of it, thanks to a very interesting novelty. Hou Yifan played the 5.Nc3 line against the Petroff, and after 5...Nxc3 6.dxc3 Be7 7.Be3 0-0 8.Qd2, Humpy uncorked the excellent 8...Qe8! After 9.0-0-0 Qa4 (the point!) Black's attacking possibilities at least as strong as White's, and just a few moves later the champion swapped queens and headed for a draw. There was some danger she wouldn't succeed, but after sweating it out to move 42 she saved her half point. 1-1.
