Rockefeller III (“Rockefeller”) National Tournament of Elementary School State Champions, and the John T. Irwin (“Irwin”) National Senior Tournament of Champions, each invited state representatives to compete through six rounds of classical chess to declare this year’s top player. 

The 2021 Champions of State Champions are: 

Denker High School Champion: GM Awonder Liang, Wisconsin 

Haring National Girls Co-Champions: WCM Ruiyang Yan, Northern California; WCM Ambica Yellamraju,Texas

Barber Middle School Champion: CM Vyom Vidyarthi, Northern California

The first-place finishers in each of the scholastic events receive a $5,000 scholarship to a school of higher learning, and winners also receive invitations to the 2022 US Chess national championships for their category: Liang to the U.S. Junior Championship, Yan to the U.S. Junior Girls Championship, Vidyarthi to the U.S. Cadet Championship, and Khmelnitsky to the U.S. Senior Championship. 

Additionally, the state representatives in each category combined for team scores in a State versus State Championship – which was won clear by the Northern California squad, boasting three 2021 champions.

Played Tuesday morning, the sixth round for each Swiss event saw several decisive results on the top boards to produce its champions. In the Irwin, Kmelnitsky finally put an end to a strong tournament run by Missouri FM Doug Eckert in a queenless Ruy Lopez Exchange. Eckert held equality all the way into a minor-piece endgame, but went astray chasing an isolated pawn – while Kmelnitsky’s knight shielded a winning passer. 

On the Irwin’s second board, Texas IM Douglas Root defeated South Carolina IM Alex Matros and finished clear second at 5.0/6, while Eckert finished clear third. For complete Irwin standings, click here.

The final round of the Denker had two games to watch, as both Liang and Oregon FM Shunkai Peng entered with 4.5/5, though the two had already played to a draw in the third round. Liang was paired with Massachusetts IM Carissa Yip, who lost on the spot after picking the wrong defense to 37. Qc8! and a strong mating threat by White at the end of a closed Ruy Lopez. 

On the neighboring board, California FM Robert Shlyakhtenko, paired up from the fourth-place group to play Peng, successfully played spoiler by holding his half-point. For complete Denker standings, click here.

Texas WCM Ambica Yellamraju did everything she could in the end, including a sixth-round stoppage to the tournament run of WCM Ruiyang Yan, who had otherwise run away from the Haring field. Yan entered Tuesday a perfect 5/5, though Yellamraju at one point behind was given the opportunity to win on demand. She made the most of it, catching Yan early in an Open Catalan, and catching her at the finish line to earn the Haring co-Championship. Yellamraju got the better of a tactically rich middlegame then slowed down for a positional endgame, harassing Yan's rook with the bishop pair and ushering White's passer to the tournament win. Yellamraju and Yan both finished at 5.0/6, with Yan taking tiebreaks and the $5,000 scholarship prize. Yellamaraju earned the $3,000 scholarship.

CM Vyom Vidyarthi found an early edge and played to a two-pawn advantage – before nearly throwing it all away in an endgame with Delaware’s Terry Luo. White missed the threat on his backwards pawn at 36. … Rh3, instead pinning his hopes on creating an outside passer – which Luo was able to corral, finding equality again after 45 moves. But Luo misplayed the rook-and-pawn endgame, while Vidyarthi did not, successfully using the Lucena position to earn the Barber championship. Practice your endgames, kids!
