Yukon tournament OSCO's biggest yet this season

Another memorable event at Independence Intermediate

The Yukon K-12 Open on January 8 was the second OSCO event hosted by Independence Intermediate School. As before, Keri Smith and her team of volunteers worked hard to make sure we could all enjoy an efficient, welcoming event. We're already looking forward to next year!


Longshots won surprise 1st-place victories in both top sections. Max Barnes scored an upset win over the heavily favored state champion in the Premier. And in the Reserve, Michael LaSala won all his matches despite being a first-time competitor in a field of seasoned veterans. Both players finished the day with perfect scores.

Tied with 3.0 out of 4 in Premier were Ryan Amburgy, Maxwell Xie, and Benjamin Li. Mason Teague scored 3.5 to finish second in the Reserve. Right behind him at 3.0 were Angelique Chen, Samuel Boudreau, Kaylee Gandhi, and Bowen Teague.

In Section 3 (U700), Alexander Kearns-Shook took first with a perfect 5.0, with Aayush Praveen and Thomas Zacharias tied for second with 4.0 points each.

The first-place trophy in Section 4 (U500) went to Grace Huang (5.0). Holley Brown, Cora Winters, Rana Kasireddy, and Alan Dodge scored 4.0 out of 5 to land in a four-way tie for second. Anurag Roy Choudhury and Nathan Reese tied for first in Section 1 (U300) with 4.5 points each, with Samuel Wang and Robert Jenkins finishing the day at 4.0.

128 players competed in five sections. Jerry Casteel was chief tournament director. Our next event will be the Casady Classic in Oklahoma City on March 5. We hope to see you there!
