    Why then did I go down from 1200 (to 1361) when I beat someone who has a rating above 1200 (1089)?? Admittedly don't have time to read the article... but hoping someone knows how this works anyway!


    The higher your rating the better. This isn't golf or anything. The grandmasters have ratings of like 2500.

    turtle, the general points system followed is as follows:

    pawn - 1pt.

    knight/bishop - 3pts.

    rook - 5pts.

    queen - 10pts.

    of course points are not everything... the position of your piece also matters.. for example you might not mind losing a bishop or rook to save a pawn on the 7th row.. and points dont have any bearing on the game result.. it is just a basic framework to help beginners understand the value of different pieces


    actually queens are worth 9pts.

    everyone starts at 1200. then as you play you get a new rating. it is all based on the Glicko ratings system :) check it out - it's a fun read!

    Rating is a measure of how accurate and timely you are during any match but the truth remains that nobody is unbeaten! Therefore, none should be underrated or overrated. Its a time !

    OK I have played several opponents now who have lost major pieces early on then just not played again so it appears they lost on time rather than as a result of their own mistakes.  Does this have any bearing on either mine or their ratings.  Seems a bit of a whimps option to me - if I screw up (and I do) I try to play it out to the bitter end.  It is still possible to get a stalemate isn't it?

    The ratings system is probably the best metric that has been developed to accurately measure a player's skill.  That being said, your rating shouldn't matter as much as striving to play a better game.  A lot of players protect their ratings like gold, and at most levels of play, it really shouldn't matter (ie. drawing a game you could have won to protect your rating) what your rating is.  Develop your game, and the rating will take care of itself.  At the end of the day, it's just a number.

    I was looking at the list of players and came across a player with a rating of 2264 from 11 games. 

     

    From the Archive list of games, the player started at 1709. That's  quite an amazing gigantic leap of 555 rating points in just 11 games.

    Well I love chess.com, but I have to critizice one thing that has to do with ratings. The rating adjustment adjusts itself to the actual rating when you end the game, I believe it should be adjusted according to the rating players had when the game began.

     

    You might wonder why?, well let's say I have 1200 rating and start a game against a 1500 player, while this game lasts I lose 5 games and decrease my rating to 900. Then I win against the 1500 guy and increase to 1300. That seems somehow unfair to me because the 1500 guy didn't expect to lose 400 rating points against a 1200.  This also works the other way around, that is if the 1200 guy increases to 1600 and then wins his fisrt game against the 1500, then he will only gain a few points, when he should win more for having faced a much higher rank opponent at first.

     The second thing is that many people, because of this, resign early from games they believe might lose, so that their rating decreases and then win another game against higher rated opponents and increase their ratings excessively. 

     

    I hope you understand my points, please get back to tell me what you think.

    On the 'Let's Play' page, it says 'Rating - Show rating adjustment' and then shows plus, minus and draw numbers.    How are these arrived at, please?

    dbalanza2, there was a discussion of this a while back on this thread:

    http://www.chess.com/forum/view/general/fast-rating-switch

     

    The upshot is that computing the rating change with the most up to date rating leads to the most accurate ratings.
