Event table notes:
Although only total scores are given here, for many tournaments full crosstables are known and are used for rating calculation.
- Edo ratings: Historical chess ratings calculated by a 'simultaneous' method, roughly on the same scale as 'Elo' ratings.
- Rating deviations (uncertainties) are listed after the ratings in parentheses.
A rating estimate is likely to be accurate to within this many rating points
(or twice as many for 95% certainty), as compared to other player ratings across the entire historical period covered.
Rating differences within a given year are likely to be more accurate than the rating deviations suggest.
- Scores are based on games actually played over the board, and therefore do not include defaulted or forfeited games
but include draws sometimes not counted in the official score.
Regardless of the official scoring system, wins count as 1, draws as 0.5 and losses as 0.
- Games counts the games actually played over the board.
Not all of these are necessarily rated as some may be against unratable players.
- Class indicates the odds class of each player.
Players in the first class gave various odds to players in lower classes; second class players gave odds to players in still lower classes, etc.
Generally, the odds for a given player pairing were determined by the number of classes separating them, as specified below the table.
