  • Players may not play up more than 100 points. (If you want to play up, add 100 points to your rating to see which section you qualify for). A player may use either their live (unpublished) rating or published rating to qualify for a higher section. If a player uses their live rating to qualify, the tournament director may also use their live rating for pairing purposes. A player may use their FIDE rating to qualify for the Premier section.
  • Unrated and provisionally-rated players policy: Unrated players may play in the Under 1400 section. To play in a higher section, unrated players must obtain special permission from the tournament director. Players with foreign ratings, FIDE ratings, and provisional US Chess ratings are not considered unrated. The tournament director may use US Chess ratings (published or unpublished) from other categories (quick, blitz, online, online quick, online blitz, or correspondence). The tournament director has the option of assigning a player a rating. In cases where a player has a provisional rating, the tournament director has discretion in determining which section(s) that player may be eligible for. The tournament director has the option to use a provisionally-rated player's live rating (regardless of whether it is higher or lower than the player's official rating) for pairings purposes and section eligibility.
  • Under 1400 section special pairings rules: The Under 1400 section will feature Monrad Swiss pairings. Monrad pairings are a variation of Swiss pairings that reduces mismatches. Monrad pairings can be beneficial in sections with wide rating ranges (such as the Under 1400 section), because players are often paired against closely rated opponents under this system.
