American junior stars GM Awonder Liang and IM Christopher Yoo finished 7th and 8th place respectively in the first event of the $100,000 Julius Baer Challengers Chess Tour, a new series of next-generation junior tournaments organized by the World Champion’s Play Magnus Group.
The Judit Polgar Challenge, named for the strongest female of all-time who also duals as mentor and commentator for the Challengers Tour, was a four-day online event beginning April 8 showcasing 20 of the world’s top emerging players aged 14-24. Featuring both males and females from 12 different countries, the junior all-play-all format saw five games per day using a rapid 10+5 time control.
India’s 15-year-old phenom Rameshbabu Praggnanandhaa ran away with the event, losing just twice and tallying 14 wins across 19 games; his 15.5 score was clear first by 1.5 points over four players in second place. Praggnanandha pocketed a $3,000 prize for his efforts, but perhaps more importantly secured a seat in the next event of the $1.5 million Champions Chess Tour, where he’ll face off against the likes of World Champion Magnus Carlsen, US Chess Champion Wesley So and Hikaru Nakamura.
The Americans’ 7-8 finish qualifies as more than just a strong appearance. The Polgar event was the first of four Challengers tournaments scheduled for 2021, and the top-8 performing players through those four events will be invited to a finale fifth knockout tournament with a $60,000 purse. In between, the junior players are scheduled to receive world-class training from coaching teams led by Polgar and her Challengers Tour co-host, former World Champion Vladmir Kramnik.
Liang, who celebrated his 18th birthday on the second day of the Polgar Challenge, tallied 11 wins with 5 losses and finished clear seventh with a 12.5/19 score. The 14-year-old Yoo finished a half point behind, winning nine games and dropping four. Liang won the matchup between them, on a pivotal third day for both players.
It was the youngster Yoo who was the early talk of the tournament, scoring 8/10 and remaining the only unbeaten player after two days of play. He closed that second day with three straight wins, including this game against China GM Lei Tingjie, which Yoo annotates.

Yoo entered the third day just a half-game off the leader Praggnanandhaa’s pace, with a chance to leapfrog the Indian in their round 11 game. There he suffered his first loss of the tournament, however, setting an ominous mood for the day that saw him drop another game to Liang and tally just a 2/5 score, which included a forfeit win.
And while Yoo was slowing down, Liang was heating up. Beginning in round 7 on his birthday, Liang put together an impressive 9.5/10 run which included a perfect Day 3 with five wins, and the lone draw coming with the black pieces against Praggnanandhaa. The streak pushed him within a point of the leader, though scoring just a half point in his final three games settled Liang in seventh place.
Yoo looked balanced again in his final day and was even able to play the role of spoiler, with an upset over Germany’s Vincent Keymer that knocked him from second to sixth place in the 19th and final round. Yoo annotates.

Also appearing in the Challengers Tour is US Chess Junior Girls Champion IM Carissa Yip, though she took some lumps against the studded international field in the Polgar Challenge, scoring just 4/19 with three wins and finishing 18th. She was able to deliver a major strike in the battle of the sexes, however, convincingly thumping Indian GM Dommaraju Gukesh, who finished third place.
The trio of American juniors will appear in the next Challengers Tour event, the Boris Gelfand Challenge, scheduled for June 10-13. Praggnanandhaa will play in the next Champions Tour event beginning April 24. For more information, visit the official Challengers Tour and Champions Tour pages.
