Chess rating system
This question gets asked a lot on ratings topics, but I haven't seen it answered....if it's been asked and answered 14 times on earlier pages of this thread, sorry:
when your ratings change, is it by the amount shown when you accepted the challenge? or are ratings fluctuations DURING the game taken into account too?
The game is rated when it ends. The anticipated rating change at the start of the game reflects current ratings, but these may and often do change during the course of the game.
Something similar takes place in OTB events. Pairings and expected gain/loss are generally based upon latest published ratings. If a player plays multiple events between rating updates (four times per year in FIDE; monthly for USCF players), these predictions will be off.
As an example, in a recent local tournament I was #2 seed based on published ratings, but when the event was rated, I was #3. One of my opponent's had gone up due to results in an intervening event between the rating publication and our event.
NO its because he'd beat the bejesus out of you on the chessboard! lol
You will know about how much you are rated once you
a) get your average opponent rating close to yours
b) get about and even number of wins and losses
example:
Rating
| Current: | 1629 |
| Highest: | 1714 (22 Dec 2008) |
| Avg. Opp.: | 1627 |
| Best Win: | 1922 (davishmcclurg) |
| Today's Rank: | #7076 of 54,646 (87.1%) |
Games
| Total: | 55 |
| Won: | 27 (49%) |
| Lost: | 24 (44%) |
| Drawn: |
4 (7%)

Anyone know the statistical distribution of ratings? I read that 400 points is a standard deviation in ratings, which the article claimed meant that between two players with a 400 pt difference, the higher rated player was 91.1% to win. I am wondering if ratings follow a normal distribution. if 1200 is average, that would mean that 95% of rated players are below 1984 (1.96x400). If this isn't how ratings work, could some stat savvy person inform me how ratings are distributed?
Yep, that's about right!
lastwarrior,
I have probably come to realize that after playing 250 games at long, I am exactly even, and my rating goes back and forth from 1210 - 1260. I guess that is a good estimate of my rating ability. However, my goal is that I can get eventually over 1300, which to me is an above average chess player, if you compare it with the population of all people who know how to play chess. And because I'm competitive I think I should always establish some sort of goal for myself.
congratulationes to chess.com , the sistem is very good thanks.
