Hi all,
Today I played against a friend who was rated roughly 250 points higher than me. I quite swiftly won by checkmate, yet I was only awarded 17 points for the win. He, on the other hand, lost 100 points. Why do I get the same amount of points for winning against someone with a very similar rating to mine, but also when I play against someone with a much higher rating?
The two games in your archive for today show a 13 point rating change for the first game but none for the second, because it was an unrated game.
Ratings do not change in unrated games.
Your rating improved by only 13 in the first game while your friend's dropped by 100 because there are two components in ratings calculations now- the difference in ratings and a statististical judgement of how accurate the ratings are.
Your friend's rating changes more rapidly because he had only played 4 rated blitz games before playing you. His rating is considered very likely inaccurate so it changes a lot from game to game until it settles down.
Yours is more settled, so it changes by much less from game to game.
