A near miss! 😲

Humpy Koneru goes into tomorrow's final round of the #CairnsCup with a half-point lead, but Alexandra Kosteniuk, Ju Wenjun and Mariya Muzychuk are still in the hunt for 1st place!

Potentially a huge day in the #CairnsCup as Humpu Koneru is winning and Women's World Champion Ju Wenjun is currently in a lost position vs. 16-year-old Carissa Yip!
