That is, Hou Yifan leads Humpy Koneru by a point and a half, not the rest of the field at the final Women's Grand Prix event of the 2013-2014 cycle. Hou's countrywoman Ju Wenjun is the current leader of the tournament in Sharjah with 3.5/4, half a point ahead of Hou and three other players. But none of that matters for the world championship cycle, as only Hou Yifan and Humpy Koneru can win the overall Grand Prix. As long as Hou finishes ahead of her rival she wins the Grand Prix, and with a point and a half lead with seven rounds to go she's in good shape.
