2021 Online Olympiad

 

The US Chess national team advanced to the final four of FIDE’s Online Olympiad 2021, defeating Kazakhstan 4-2 in blitz tiebreakers in a decisive quarterfinal match on Monday.  

The exciting playoff saw just one draw across 18 games, with the six-board American lineup both needing and receiving several clutch moments from each of its players to advance. Team USA was pushed into comeback mode after dropping the first of two 15+5 rapid sets to begin the match, but equalized in the second set by the slimmest of margins: a 3.5-2.5 score to force the 3+2 blitz tiebreaker. 

The U.S. squad now moves on to a semifinal on Tuesday at 11:30 a.m. eastern against India, co-winners of the 2020 digital global team event whose lineup includes former World Champion GM Viswanathan Anand. The winner will meet that of the other semifinal between Russia and China in the Olympiad finals on Wednesday

Team USA 2021 FIDE Online Olympiad

 

Advancing past a strong Kazakh national team was anything but certain for Team USA, which didn’t find itself firing on all cylinders until the final set of games on Monday. The frantic, anything-can-happen rapid time control revealed its sharp edge on two of the American top boards in the first round: Approaching a balanced endgame, the 2700-classically rated super-GM Jeffery Xiong inexplicably overlooked a simple attack on his rook, while time trouble caused the considerable advantage of Olympic veteran GM Irina Krush to slowly bleed into defeat as Black in this Rauzer Sicilian against World No. 14 woman GM Zhansaya Abdumalik.

GM Irina Krush in the 2021 Online Olympiad

GM Irina Krush rebounded after a tough opening loss to win her next two games over World No. 14 woman GM Zhansaya Abdumalik in the 2021 FIDE Online Olympiad.

 

But both Xiong and Krush were heavy lifting for the remaining match, rebounding to score a combined 4/4 in their second rapid and blitz tiebreaker games. Xiong smashed through the stigma of the Berlin set up by Kazakh GM Rinat Jumabayev, who had infamously bounced his American compatriot GM Fabiano Caruana in the third round of the FIDE World Cup last July, with this convincing mating attack in the second set of rapid games on Monday.

With wins from Xiong and Krush adding to the quarterfinal’s only draw by GM Ray Robson on the second board, IM Nazi Paikidze delivered the goods when Team USA needed it the most. Here the two-time U.S. Women’s champion Paikidze, swapped into the second-set lineup by American captain IM John Donaldson for IM Anna Zatonskih, turned around an uncomfortable opening as Black in a Kings Indian Attack after finding a killer outpost at 24. … Nc3.

The American squad finally looked whole again in the speedy 3+2 blitz tiebreakers, finally receiving contributions from its juniors. Both FM Thalia Cervantes and GM Awonder Liang had been the undeniable force behind Team USA’s arrival in the Online Olympiad playoff bracket, the squad’s top scorers through the divisional first stage with a 6.5/9 and 7.5/9 on the U20 boards -- though the two youngsters nearly ghosted against Kazakhstan on Monday, combining for 0/4 through both rapid sets.  

They both found their form at the right time, however, delivering convincing wins in the clutch during the blitz overtime. Cervantes broke through several-hundred rating points and the Kings Indian Defense of World No. 9 Junior Girl IM Bibisara Assaubayeva, while Liang finally figured out IM Ramazan Zhalmakhanov to finish this Chigorin with checkmate on the board.
