Jenks K-12 Open

A scholastic chess tournament for all K-12 players

The deadline to register for this event is Thursday, March 7!

Jenks Middle School
3019 E. 101st Street in Tulsa, Oklahoma


The Jenks K-12 Open
Saturday, March 9, 2024



Doors open. There is no check-in; all registered players will be paired.


Round One for all sections will begin following announcements in the playing hall. 

Subsequent rounds are paired ASAP with a break for lunch*. Awards ceremonies take place for each section ASAP after that section's final round is complete. 


*Lunch is usually after round 2 or 3, depending on how long the morning rounds are taking in your player's section. To avoid being later for the after-lunch round, parents are advised to keep players onsite rather than taking them out for lunch.

Spectator Policy

Spectators are not permitted in the playing hall while games are being played. Players must exit the playing hall after finishing their games and reporting their scores.

When the first round is paired, parents are encouraged to accompany their players as they find their boards and listen to morning announcements. You may remain for the first five minutes of the first round only to observe your player and take a photo. After the first five minutes, we will ask you to return to the waiting area.

Parents who wish to escort their players into the playing hall for rounds 2–5 may do so. But since there will be games in progress and we will thus need to keep the playing hall quiet, no talking while finding your child's board, please, and return to the waiting area immediately once they are seated.


Sets are provided for tournament games, but players are encouraged to bring their own for skittles (waiting area).


Clocks are provided in U1200 and Premier, but players with approved clocks may use them in all sections. If you have one, please bring it.  If you need a clock, please consider purchasing one of these tournament-suitable clocks from Wholesale Chess. A portion of each sale will be donated to OSCO. 

Scoresheets and pencils are provided. Notation is required in Premier and encouraged in all sections.
