Revision as of 17:47, 9 July 2009

Starting July 2009, this page features detailed tournament results (also known as cross-tables) 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.

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.

Each month’s results are available as text only for viewing on small screens or slow connections; or in a graphical format with player photos, for viewing on large screens or fast connections.

How to read the results

Segments

Long tournaments are split-rated in multiple segments as follows:

• Tournaments of 16 or fewer rounds are rated in a single segment.

• Tournaments of 17 through 35 rounds are rated in two approximately equal segments.

• Tournaments of 36 or more rounds are rated in three approximately equal segments.

If the segments must be of unequal size, then earlier segments are assigned extra rounds.

Text cross-tables have one listing per segment, followed by separate listing of final standings when applicable. Graphical cross-tables have one listing per tournament, with a pair of rating columns for each segment.

Graphical cross-tables

The graphical cross-tables feature the following information:

Rank

A player’s rank at the tournament, based on their wins, losses and spread. (This may not be equal to the official final placement, as it does not reflect certain adjustments).

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.

Text cross-tables

The text cross-tables feature the following information:

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.

Printing

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