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.  


I'm not really sure that what you said is right-no offense. But it does make sense.

I have read many of the articles re ratings but none seem to addres the question of what percentile each raing falls into.


 A table would be more precise, but the info is essentially there in the rating graph:

 we had it that way to start i believe, and then changed it. no matter which way we do it somebody will like it the other way :) i like it the way it is because a rating is an approximation of your strength, and the most RECENT rating is the most accurate. it isn't about managing your rating - it's about having an accurate rating.

I'm not too sure what Mikee is saying here. If the inference is that chess is only for fun and practise, then they should play another game. Chess is a war game. There is no fun in war...only the enemy. We are not practising anything..we are analysing what our opponent is doing and trying to outmanoevre them. Perhaps the word "enjoyable" would be more apt than fun. Chess is a serious game to be enjoyed.

I have a real life chess rating, and it is way, way lower than the one here.  I have spoken to a few players, and they all report the same rating inflation.  There is a trick you can use if you want to inflate your rating further - never play anyone with a low rating -- you can loose big time, they can only gain --- ever noticed the not less than massive rating requests? - OK I suppose if you are that good, perhaps playing us mere mortals is a bit below them, but as far as I'm concerned it does not matter, it's a just a game --- or is it?????

 

Here's a link I think gives a fairer estimate ... http://www.chessmaniac.com/ELORating/ELO_Chess_Rating.shtml

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


My chess teacher has taught me a queens is worth 9

Rating is helpful for finding your apropriate match for the day. Whatever class you choose to play for that day.

Well, I instead have a complain. Since my first game, till now ( i have played 20 till now), I didnt get a single opponent over the rating of 2000. Because nobody wants to play. I have won all of my 20 games. with a 100% win record. Now some of my opponents are complaining, that i am using some sort of measures. This is disgusting. Well, I just demand that I should play with the player of my level. Then , may be, also if I win, atleast nobody can raise words against me.

My grading by the way was 1288 ( 344 points lower ). Anyway, because he thought i was an easy win, started doing things that he wouldn't have done against a stonger player, such as castling when he should of, etc...Anyway, he ended up losing, and then to top it off, started having a hissy fit strop by accusing me of messing with the clock during his move ( both on the flag ). Luckily everyone who'd finished was watching our game, and promply corrected him that nothing of the like occured.

i agree i played 4 cornwall mens this year against devon im not actually fide rated but im ecf'd at about 120 and i was playin a 150 he thought i was gonna be easy so he got into a dodgy nimzo indian as white and i fought and got a draw

this is a great and interesting post thread. i personally think that i am a good chess player yet i wont play people anymore because i feel too pressured with the psychology that is ratings. they are a paradox as you couldnt have chess without them as there would be no emphasis to win, but myself personally i dont think i can play chess with them. in chess the saying its the taking part that counts could not be less true, as winning is everything, therefore ratings are an integral part of the game.

That is so true, I once had to give up a knight and a rook to gain position for the mate that I got within the next couple of moves... I was proud of myself. lol   But I've been told to keep in mind that having two bishops is more powerful than one bishop and one knight and likewise two bishops are stronger than two knights.  I'm guessing because the two bishops can command both colors and this always isn't the case with two knights.  Any thoughts on this?  I think I'd personally rather have 2 bishops rather than two knights.
