The Oklahoma Scholastic Chess Organization (OSCO) provides chess tournaments for K-12 students throughout Oklahoma. We are an all-volunteer 501 (c)(3) nonprofit. If you would like to volunteer, connect us with a potential tournament venue, or make a donation, contact us at board@oscochess.org.
Schedule
8:45 Doors open. There is no check-in; all registered players will be paired.
9:30 Round One for all sections will begin following announcements in the playing hall.
-
Subsequent rounds are paired back to back with a break for lunch.
-
Most sections have 5 rounds and players will be eligible to play in ALL rounds. This is not an elimination style event.
-
Awards ceremonies take place for each section after that section's final round is complete.
For late arrivals or last-minute cancellations, send a text to 707-685-7045. This helps us start on time and avoid pairing players with no-shows.
