Revision as of 15:16, 9 July 2009

Starting July 2009, this page features tournament results for all sanctioned tournaments.

The results are filed according to the month in which they were entered into the rating system: if a tournament is held late in a month, its results may be filed under the following month.

Detaled tournament results (known as cross-tables) are available here two formats, “older” and “newer”. The older format contains text only and is suitable for compact viewing on a low-bandwidth connection; the newer format with pictures and scores is suitable for faster connections. The results are also copied from this web site with a slight delay and made available on our partner web site cross-tables.com with more extensive statistics.

Recent results

Results before July 2009 are available courtesy of the NSA.

Newer cross-tables

The newer cross-tables feature the following information:

Rank
A player’s rank at the tournament, based on their wins, losses and spread. May be incorrect if a director has submitted bye-related data in a deprecated format.
Name
A player’s name as it appears in the ratings list.
W-L
A player’s record of wins and losses. Byes count as wins, forfeits as losses, and ties as half-win/half-losses.
Spread
The difference between the number of points a player scores and the number of points scored by all of the opponents.
Rating
A pair of columns with a player’s rating according to the rating system in effect for this tournament. If more than one pair of columns is given, this event was split-rated because of its length.
Old
A player’s pretournament rating.
Perf
A player’s performance rating, representing the player’s strength counting only this event.
New
A player’s post-tournament rating.
Rd. N
A player’s rating after the specified round.
+/−
The difference between the player’s pretournament and post-tournament ratings.
Round-by-Round Results
A player’s list of opponents, with photos where available (hover mouse over photo for name), one of WLTB (win, loss, tie or bye), opponent rank, player score and opponent score.

Older cross-tables

The older cross-tables feature the following information:

NAME
A player’s name as listed in the rating list
OLD RATING
A player’s rating before this tournament segment
NEW RATING
A player’s rating after this tournament segment
PERF RATING
A player’s performance rating during this tournament segment. I.e., the old rating that they would have had to have had for it to have remained unchanged as their new rating.
RESULTS
A player’s win-loss record, showing whether they had a win (W), tie (T), loss (L) or forfeit/bye (B), and the number of their opponent that round.
WINS
A player’s number of wins. Half wins may be displayed using a ‘+’ sign.
SPR
The number of points by which a player has outscored all of his or her opponents.

Tournaments longer than 16 rounds are rated in two approximately equal segments. Tournaments longer than 36 rounds are rated in three approximately equal segments. If the segments must be of unequal size, then earlier segments are assigned extra rounds. Older cross-tables have one segment per cross-table. Newer cross-tables have one tournament per cross-table, regardless of how many segments the tournament may have had.

Printing

Cross-tables are large and usually print better in landscape orientation, reduced to less than 100% of nominal size.
