How are ratings determined
How are the 'points' you lose or gain determined? There seems to be no rhyme or reason. A person I am playing received 256 points on his rating when he won a game he played with someone rated close to him.
When I've won against a player rated 300-400 above me, I get 13-16 points added to my ranking ????
I'm a 1200 player. I won against an 1840 player on time and got 13 points. I know winning on time is not the same as winning by checkmate or resignation, but still ??
Can anyone clarify this for me?
