20 Aug 2018 - OSCO 2018-2019 Rule Changes

Any questions about these changes, the 2018-2019 tournament schedule or OSCO events can be directed to the OSCO board at admin@okschess.org.

Change in Tournament Registration Fees to Encourage Advance Entries and Timely Start Times

The OSCO board has approved changes to tournament fees for the 2018-2019 season. This is the first increase in entry fees since 2002. Tournament registration fees will be $20 per player REGISTERED IN ADVANCE for regular season events. Door registration will be $25 for the same events. The Grade Championship, Blitz Championship and State Championship fees will be $25 in advance and $30 on the day of the tournament. The higher door registration fee is due to persistently large numbers of last minute registrations and will assist OSCO in starting events on a timely basis.

To be considered an ADVANCED ENTRY, players must be registered online by 5:00 PM the Thursday before the tournament. In addition, a FIRM CUTOFF time of 8:30 AM will be enforced to ensure that tournaments can begin on a timely basis. Any player registering after 8:30 AM will receive a ½ point bye for the first round.

New Club Team Classification

The OSCO board has approved a new class of Club Team awards for the 2018-2019 season. The new Club Team rules leaves intact the legacy School Team definition and the competition and awards for those teams completely unchanged. Those teams not satisfying the school team definition must compete as a club team, if they comply with the definition below.

A “Club Team” will be defined as a group of players that regularly meet and practice together, with published meeting time and place available online to allow verification that the team members actually do meet. Club teams will include the same number of player scores as is used in the same event for school teams, due to pairing software limitations. At the beginning of the season, a player will have to choose whether to compete with a school team or club team for that season. Only one change will be allowed per school year. Players may not compete on a new team for the first time at the state championship. In order to maintain the integrity of the Club Team definition, players found to be participating in tournaments as a Club Team member but NOT meeting and practicing as part of the Club Team will be subject to a one game suspension of both the team and player on the first offense and for one calendar year for repeat offenses.

Any Club Teams forming must notify admin@okschess.org or the tournament director so they can be added to the online registration list of teams. Their team code will be prefaced by an * for visibility on the team standings.

A “School Team” is defined as a group of players that must have their primary enrollment in the same school. No combined schools are allowed. A school is defined as the same building or connected buildings under the same name. If homeschool players (none in any K-12 building most of the school day) are meeting and practicing together, this group may compete as a school team.

Team awards at non-championship events will be for individual sections 1-3 plus a combined team award for sections 4-6. Section 5 will have a 1.5 point adder for difficulty and one less round (see below). Premier will have a 2-point adder accounting for the higher difficulty.

New Player Awards

In addition to new awards for Club Teams, OSCO will be adding full season awards for the Most Improved Player in each section (per beginning of season age and CXR Best rating) and for the Most Improved Player in OSCO overall based upon CXR SEASONAL Rating increases during the 2018-2019 season. In addition, Upset Awards will be awarded for the player recording the largest upset based upon his/her rating versus opponent as follows: all sections at the Grade Championship, Open/Premier sections at the State Championship, the 700+ section at the Blitz Championship and the top 2 sections at all non-championship events.

Sections at Non-Championship Events

In order to better balance the size of the upper sections, Section 4 U900 is changing to U800 with U700 remaining as the ceiling for Sections 2-3. Section 5 will be U1100 and have an upset award due to the wide and difficult rating range. Premier is still Section 6 and the top-rated section with those having either CXR Peak or USCF regular current rating over 1099 required to be in that section. Sections 1-5 eligibility will now be based on CXR Best/Peak rating to eliminate sandbagging, or the Unofficial if no peak rating has been established. Section 5 will have the same number of rounds and time control as Premier. Players may play-up to a higher section based on any CXR Peak/unofficial or regular/quick USCF current/published rating within 100 points of the ceiling of the next lower rated section.

New Qualification and Tiebreaker Rules for Denker, Barber and NGIT Representatives

OSCO will select three individuals to represent the state of Oklahoma in the 2019 Denker Tournament of High School Champions, the 2019 Barber Tournament of K-8 Champions and the 2019 National Girls Invitational Tournament. Points will be awarded to players in the Premier Section (with the exception of the State Championship, where Barber contenders will participate in the 6-9 Open) at the following qualifying events:

September 15, 2018 –OSSM / Cleveland Elementary K-12 Open
October 13, 2018 – Tahlequah Sequoyah High School K-12 Open
December 8, 2018 – OKC Area Open
February 16, 2019 – Jenks High School K-12 Open
March 9, 2019 – Oklahoma Scholastic State Championship

The player with the highest total number of points, which is the sum of their TWO best OSCO regular season events (top 4 above) PLUS their final score at the state championship multiplied by two, will be the Oklahoma nominee. PARTICIPATION IN THE STATE CHAMPIONSHIP IS MANDATORY.

The player must meet all qualifications specified under the USCF rules for each tournament. If the Oklahoma primary nominee declines the opportunity to play, then the player with the next highest score will become the primary nominee. Female participants will have the option of playing for the Denker/Barber or NGIT nomination.

Updated standings for each event will be posted on the OSCO website prior to the next qualifying event. In the event of a point tie for eligible players, the following criteria will be used as a tiebreaker:

• 1st Tiebreaker: Head to Head Results at State Championship
• 2nd Tiebreaker: If no head to head match occurred at State Championship, the 2nd Tiebreaker will be head to head results at all 2018-2019 Qualifying Events
• 3rd Tiebreaker: If a tie still exists, a head to head match will be held at the April OSCO tournament. The tiebreaker will consist of 2 classical games (G/60, alternating colors).
• 4th Tiebreaker: The final tiebreaker will be an Armageddon match.
