Verified foreign ratings may be used if reliable conversion is possible.
FIDE has updated all ratings. We convert the new FIDE ratings to USCF by the following formula
- USCF = FIDE + 50, if FIDE greater than 2200
- USCF = FIDE + (2300 – FIDE)/2, if FIDE between 2100 & 2200
- USCF = FIDE + (FIDE-1800)/3, if FIDE between 1800 & 2100
- USCF = FIDE if FIDE less than 1800
June FIDE ratings will be used for the Open section, official June US Chess ratings will be used for all other sections. Other ratings, including US Chess online ratings, may be used if higher. If your rating changes in the June supplement you will be moved up automatically or down on request. Players rated more than 100 points higher than the section limit during the last year may be moved to a higher section.
For a US player US Chess ratings are usually used even if the player has a FIDE rating. For foreign players the highest of US Chess, FIDE or other national ratings is used. The Chief Tournament Director may use whichever rating he believes most accurately reflects the player’s true strength.
