The Oregon Chess Federation, Oregon’s primary U.S. Chess Federation affiliate, hosts the Oregon Junior Closed Championship each year. The top six junior players in the state are invited to participate in a 5-round round robin event at the end of the year, with the winning player invited to the Oregon Closed Championship in early 2017 (as long as they meet certain rating requirements). For more information, see the OCF bylaws here.
Historically, the six invitations to the Junior Closed are extended to (1) chess players under the age of 19 as of the date of the tournament, (2) who have played at least 15 USCF rated games over the last year (so 10/01/2016 to 10/01/2017), and (3) are based on the highest post-tournament rating during that period, averaged with the player’s October 2017 rating (as published in the USCF October).
This year the tournament will be triple rated: NW Scholastic – US Chess and FIDE.
I will email the invitations after October 1st.
