After a much-needed rest day, the World No. 20 Indian, playing with white pieces, started the game wary off his opponent's attacking prowess.
However, he gradually started shifting gears and forced the Chinese Grandmaster to commit mistakes, and as soon as she did, Harikrishna capitalised on it.
"It was an equal game but I kept pushing and she gave me a chance to push G4 on the 38th move and thereafter the advantage was with me and I won the game," the 31-year-old from Guntur said after a long and gruelling game.
Harikrishna will be up against the top seed of the tournament, David Navara, for his seventh-round game.
Even though Navara is down the pecking order in the points tally, Harikrishna will be wary off his attacking prowess after the defeat in the final of the Rapid Tournament against him.
