World rapid champion Koneru Humpy and fellow Indian Dronavalli Harika settled for contrasting draws in the fourth round of the Cairns Cup chess tournament. Humpy was held to a 37-move draw by Kateryna Lagno of Russia in a Grunfeld Defence game while Harika could not force a win against American Irina Krish in a Paulsen Sicilian game on Monday. Humpy and Lagno shared the point in a quiet game while Harika and Krush battled it out for 44 moves before signing the peace treaty.
