It's what happens to your rating when you win, lose or draw. For example, if in your first example, you were to draw, you would gain 1 rating point. Or, if in your second example, you were to lose, you would lose 9 rating points.
Win,Draw,Lose details? What do they mean?
but how does this get factored in?
what helps decide that you lose 9 points instead of maybe 11?
what rating range has what win/draw/lose ratios?
Whenever I play Online chess, down in the bottom, in games details you see the time controls, the side you play as, and then the numbers.
win: +16, draw: +1, loss: -14 or
win: +20, draw: +6, loss: -9.
What do these numbers mean?
