Resolved: Rating

Hi everybody, I'm trying to find an explanation about the rating, how do they work? I've foung some stuff about Glicko, ELO, etc.. but I'd like to understand them with easy examples.

I guess, time and rating from your opponent is important in the equation.

And another question is: if your opponent is losing clearly the game and he/she resigns, do I become the same rating as if I won him/her for example?

Thanks in advance for your answers.

Thanks Baldax.

Elo does not take into account previous play. "The winner of a contest between two players gains a certain number of points in his rating and the losing player loses the same amount." http://en.wikipedia.org/wiki/Elo_rating_system  It does NOT become more difficult to change a rating.

Chess.com uses Glicko. Glicko takes into account your, and your opponents, previous play using an RD. On this site you start with a high RD of 350. If you stop playing it returns to 350.

The more frequently you play, the lower your RD. It does become more difficult to change a rating. Your rating is considered more reliable and does not change much from game to game.

Your Blitz stats:

Your opponent's RD also comes into the equation. If he has a high RD his rating is considered unreliable so it does not affect your rating much. You can play all the unreliably rated players you want without "fear" of losing a lot of your rating.

There are no easy examples.  http://support.chess.com/Knowledgebase/Article/View/16/0/how-do-ratings-work

No rating system cares how a win is decided. It is sad indeed how often people ask about differences between resignation and checkmate.

Thanks TadDude !

Really not fair, I was winning some games and the adversaries just resign, so I didn't get the points for the expected victories .... not fair !

"It is sad indeed how often people ask about differences between resignation and checkmate." It is sad.. so sad indeed.
