Born to Nageswara Rao and Padmavathi, agriculturists from Prathipadu village near Guntur, Andhra Pradesh. The family had financial difficulties; a doctor once advised quitting chess at age 6 due to headaches. His maternal grandfather Ranga Rao was his first chess teacher and biggest influence, traveling unreserved on trains with the young Harikrishna to tournaments.
Grandfather Ranga Rao was a village chess enthusiast who recognized Harikrishna's talent when the boy solved a chess problem at age 5 that adults had missed. Grandfather became his first coach and dedicated supporter, despite family pressure to focus on studies. Parents were agriculturists with no chess background.
Harikrishna learned chess at age 4 from his grandfather in a village near Guntur, India. Despite financial hardships and a doctor's advice to quit at age 6, he won the World Under-10 Championship at 10 and became India's youngest grandmaster at 15 in 2001. His grandfather was his first coach and most dedicated supporter, traveling unreserved on trains to tournaments. The family were agriculturists with no chess background, making Harikrishna's rise largely self-driven with grandfather's mentorship. He later received formal training from G.K.
