Chess rating system


I am fairly new to this but appreciate the help. When I lose a game, I drop around 10 points. When I win, I gain 5! haha. Doesn't seem fair. Can someone explain it to me please?

Points you lose or get depends on the rating of your opponent. When playing a stronger opponent, you lose less points if you lose and you gain more points if you win. Opposite when playing a weaker opponent.
Hi I was wondering how many classic rated ACF games you had to play before you acquire a classic ACF rating.
I love chess and sometimes I am surprise myself because I feel I'm playing good against strong players
but with my up & downs my rating easely change from 1600 t0 1300 but most of all I play for fun!

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.

is the rating on chess.com unofficial? how could we get official rating with certificate.
"Official rating with certificate" implies that you are talking about titles such as CM, NM, FM, IM, GM and so on.
In order to get an official title (that matters), one must play over the board tournaments in officially sanctioned events. If you live in the US, there are USCF events and some FIDE events. If you live in Mongolia, I believe your only real choice is FIDE. Other countries do have national ratings systems too tho.

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
A Queen is 9 points
Even the champions have bad times in their games and lose games. Learn from your mistakes and you will improve eventually.
I have learned success in things is never a smooth path, its got lots of ups and downs along the way.
