Indian Grandmaster Pentala Harikrishna has held world no. 6 Shakhriyar Mamedyarov of Azerbaijan to a thrilling draw in the third-round clash of the Geneva FIDE Grand Prix. The world no. 22 Indian, playing with white pieces, attacked from the onset and found himself in a winning position but a slight miscalculation saw him surrender the advantage to the second seeded Azerbaijan player. Harikrishna is tied second with two points, courtesy a win and two consecutive draws. The 31-year-old from Guntur will take on another Azerbaijani Grandmaster and table topper Teimour Radjabov in his fourth round encounter later tonight.
