Chengdu: India’s Grand Master Harika Dronavalli had to endure a long and complicated game against World No.5 Anna Muzychuk of Ukraine to earn a critical draw and another half point in the Fide Women's Grand Prix chess tournament here on Friday. She is tied at number two with Ju Wenjun (China) and Stefanova Antoaneta (Bulgaria) at four points at the halfway stage. India's Koneru Humpy is leading the table with 4.5 points. Harika blundered on the twentieth move but got away with it as Anna too made a critical mistake immediately after. She quickly equalized the position and fought tooth and nail for 30 moves to ensure the draw. “Today’s game was very interesting. We both played a long theory and got into a very complicated position. I made one bad move but somehow managed to retrieve the situation," said Harika. Harika will take on Humpy on Saturday in what promises to be an exciting tussle.
