Chess rating system

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!

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!

basically:
everyone starts out with a rating and a variable that determines how accurate your rating is. if you haven't played any games, then that variable is HUGE and allows your rating to swing more aggressively. but if you have played 1,000 games all very recently, then you have a low variable, so your rating will move more slowly. also, your opponent's variable matters. if they have a very loose variable, your rating will move less than if they have a tight variable.

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

Oh yes it does! How well you play includes how well you manage your time. Time is as much part of Chess as it is in other games. In football you could score the greatest goal in history, but if the referee blows time before it goes in it doesn't count. Similarly in Chess if you don't get your moves in within the time, you lose, and correctly so.
I could be wrong, but I assume she's talking about blitz games. There are lots of people who are great blitz players but terrible in long games, and vice versa.
In playing my first game on Chess.com, I received a rating of 1200, before I played. Why, and how was that arrived at?
