You can find out more about the rating system used here at:
http://support.chess.com/Knowledgebase/Article/View/16/0/how-do-ratings-work
chess.com uses the Glicko Rating system, a bit more complicated than a simple ELO system, as it also factors in frequency of play.
so it jumps up because basically every player new here starts at 1200 rating but they don't know for sure if my strength is really 1200.. so as i continue to finish games they will have more data to compare to and thus they will give a more accurate rating..
okey thanks alot.. it sure helps clarify things for me.. (plus i learned a thing or two for reading the article
)
just yesterday, i was still unrated player.. i won a game by checkmate and suddenly i have a rating of 1385.. then one of my opponent resigned and my rating jumped up from 1385 to 1477..
its a good thing that my rating reached this high but i'm just a little confused.. how is the rating calculated here?
thanks in advance for someone who could clarify..
