With a 3.5/4 score and a win over the highest-rated scholastic player in the state, Elizabeth Braddy became the 2024 OSCO State Champion. Her win put her at the top of the races for two national invitational tournaments: the Denker and the Haring (for high school and girls state champions, respectively). As in past years when she has qualified for more than one event, Braddy chose to represent Oklahoma at the Haring. Our other national invitational representatives are Oscar Wang (Denker), Aayush Praveen (Rockefeller - elementary), and Lafayette Chen (Barber - middle school). 


The Oklahoma Scholastic Chess Championships were held on Saturday, April 13 at the University of Central Oklahoma in Edmond. Josie Braddy was chief tournament director and organizer. She was assisted by TDs Joe Veal, Frank Chen, Leo Xie, Fiby Li, and Joel Gargus, who ran the DGT broadcasts of the top boards in both the middle and high school championship sections. 

Results are here and you can view some of the top games from the event here. A list of winners is below.

A record-setting win and a stunning comeback

The Jenks K-12 Open, March 9 in Tulsa
by Joe Veal

Some scripts are better than Hollywood.  Two surprises at the Jenks K-12 Open, held at Jenks Middle School in Tulsa on March 9, made for a memorable event.

Eight-year-old Arya Roy Choudhury (the 6th seed of 21 players), a second grader from Edmond, became the youngest-ever player to win a regular-season OSCO Premier (1200+) event in our history, scoring 3.5 out of 4. It is unclear what the future will hold for Arya, but these days are quite bright indeed.

Section 4 (900-1199) at the same event presented another surprise. The 25th seed out of 25, Zion Wright stunned onlookers by tying with the 2nd seed Nazar Kanatov with a perfect 4.0 out of 4. Wright was awarded 1st place because Kanatov did not show up for blitz tiebreaks. Zion's USCF rating going into this event was an established 451, and this begins a tale.

Eight years ago, when Wright was a player I coached at Wilson Elementary, Oklahoma scholastic tournaments were rated by Chess Express Ratings (CXR), not US Chess*. Wright's CXR rating was around 800.  Since there were fewer opportunities in those days for Oklahoma youths to play in non-scholastic tournaments, Wright had very few US Chess-rated games and a barely established rating of 451. He was only permitted to play in Section 4 due to his online blitz rating. 

The event drew 219 players who competed in five sections. Section winners are below, and you can find the full results here.

*Except the Premier section, which at that time was for players 1100+ and was rated by both CXR and US Chess. OSCO stopped using CXR in 2020 and began rating all games through US Chess .


Arya Roy Choudhury (3.5/4)


Zion Wright & Nazar Kanatov (tie, 4.0/4)


Liam Bond (5.0/5)

4-6 U600

Andrew Shirley & Nico Perez (tie, 4.5/5)


K-3 U600

Erqing Wang (4.5/5)

OSCO player wins U1600 at Texas Winter Championship

Our congratulations to  Oklahoma player Anurag Roy Choudhury, who took first place in the U1600 division at the 2024 Texas Winter Championship.  Way to go, Anurag! 

The event was held Saturday, January 20 at the Texas Chess Center's location in Frisco. David Gaston was chief tournament director. 


with Joel Gargus

This position was reached on the top board at the Deer Creek K-12 Open. What's kind of cool to me is that this exact position is also studied in Dvoretsky's Endgame Manual, which is widely regarded as the most comprehensive endgame text ever written.

It's White to move. Can you find the winning idea? Fortunately for you, there is no time pressure as there was for White in the game. There is more than one defensive try for Black, so be sure to plan for that!

Joel Gargus is the director of the Oklahoma City Chess Club and a regular TD at OSCO events.

The Deer Creek K-12 Open

Saturday, January 6 in Edmond

The Deer Creek K-12 Open was held Saturday, January 6 at Deer Creek 4th & 5th Center in Edmond. 191 players competed in five sections. Stillwater 10th grader William Lin took first in Premier, landing himself at the top of the list of contenders for this year's Denker Tournament of High School Champions. As of this month, the leaders for the other invitational tournaments are Lafayette Chen (Barber), Arya Roy Choudhury (Rockefeller), and Elizabeth Braddy (Haring). Two tournaments remain in this year's scholastic series; our representatives will be named following this year's state championship. 

Other section winners were Kirthika Duggisetty (K-12 U1200), Tanner Woodson (K-12 U900, after a blitz tiebreak round with Rafael Perez), Benjamin Livingston (4th-6th U600, after a blitz tiebreak round with Vaibhav Thaduri), and Wyatt Morris (K-3rd U600). 

Crosstables are here. Some photos are below; more will be posted soon. Our next tournament is March 9 in Jenks. We hope to see everyone there!
