Young Grandmaster R Praggnanandhaa on Friday won both rapid games to eliminate second-seeded Hikaru Nakamura to enter the last 16 of the FIDE World Cup chess tournament here.
After the two classical games ended in draws, the 18-year-old Indian, who celebrated his birthday on Thursday, stunned the American GM in the tie-break games today.
Five-time world champion and Indian chess legend Viswanathan Anand hailed the young GM and said, "Praggnanandhaa does it! Eliminating one of the pre-tournament favourites Hikaru Nakamura to go through to the next round. A truly impressive performance by Prag!" Praggu, as he is known among fans, was joined in the last 16 by fellow teenager D Gukesh, who ousted Andrey Esipenko.
Praggnanandhaa will meet Hungarian GM Ferenc Berkes in the round of 16.
However, another Indian - Nihal Sarin- bowed out of the competition, losing both the tie-break games to Ian Nepomniachtchi in the fourth round.
Indian players Vidit Gujrathi and Arjun Erigaisi had already secured the last 16 berths.
In the women's section, D Harika advanced at the expense of Eline Roebers, winning the rapid tie-break.
However, the country's No.1 women's player Koneru Humpy was ousted by Bella Khotenashvili (Georgia) as she lost both the tie-break games after the two-match classical series had ended 1-1 with each player securing a win.
Harika is the only Indian player remaining in the women's event.
