Terms & FAQ

Rank - The current rank of the player in this event.

Number (Number) Number - The numbers under a player's name are their pre-tournament rating, current estimated rating based on their permformance in this event, and their USCF ID number.

½ Bye - The player requested a bye for a round before the tournament and received half a point for the round.

Forced Bye - There was an uneven amount of players for the round and one player was given a bye with a full point awarded. The forced by is typically given to the player with the lowest score/rating that has not received a forced bye in the tournament. The USCF rules for which player gets the forced by are rather specific and do not allow for much judgement on the part of the tournament organizer.

TBMM - In the Modified Mean system, players who tie with even scores have the highest and lowest scoring opponents' scores excluded. Players who tie with plus scores have their lowest rated opponents' score dropped. Players who tie with minus scores have their highest rated opponents' score dropped.

TBS - Solkoff, the same as modified mean but no opponents' scores are dropped.

TBC - To calculate this, sum the running score for each round. For example, if a player has (in order) a win, loss, win, draw, and a loss; his round-by-round score will be 1, 1, 2, 2½, 2½. The sum of these numbers is 9. This system places more weight on games won in the early rounds and the least weight on games won in the final rounds.

TBS - This sums the cumulative scores of the player's opponents.

P2 - If a contestant has a "P2", "P4", "P6", etc beside their initial USCF rating it means that their rating is only based on that many games. USCF ratings become more accurate with more games played.
