Hyderabad:Koneru Humpy is busy making tactical changes in her game style before she leaves for tournaments next month. The World Junior chess champion from India has set her eyes on getting a third GM norm. Back from her twin triumphs at Budapest and Belgrade, 14-year-old Humpy told NDTV that her immediate aim is to get a third GM norm and beat the long-standing record of Judith Polgar. That will also make Humpy the first Indian woman to achieve the men's GM title. "She (Polgar) became the youngest Grandmaster at the age of 15 years and five months. So I want to be a Grandmaster in less than 15 years, 5 months," Humpy said. Humpy is making changes in her game style to improve her attack. "I have to improve my middle game and end game positions. I have to improve my style and in the opening preparation, I feel that I should prepare some more new openings." "Previously, she used to play positional games. She concentrated on defending her games most of the time. But from the last two tournaments, she changed her strategy and she is going for attack," said Koneru Ashok, Humpy's father and coach. In December, Humpy will compete in the First Saturday GM tournament in Budapest and the Third Saturday GM tournament in Belgrade. A good showing will improve Humpy's current Elo rating of 2484.
