# how do you maximise the points you gain from winning

Just as the title suggests, how do you increase the points you gain from winning in the chess.com app. Just won a game by checkmate, and before winning I was 23 points ahead, but only gained 17 points to my rating. I believed I would win more points than 17. So how is it calculated?

The way the game ends (checkmate, stalemate, resignation, time forfeit, etc) doesn't affect the rating change.

The amount of pieces captured also makes no difference.

The rating formula takes into consideration 4 numbers:

3) A universal multiplier that the website or organization can adjust to increase or decrease gains and losses (for example you wouldn't want people to lose and gain less than 1 point, or as many as 100 per game).

4) A multiplier for each individual that the formula self adjusts based on the reliability of a player's rating. This is known as your RD. Reliability basically means how frequently you play. For example new players really will gain or lose 100s of points for a win or loss, but only because they're new. The more they play the more this multiplier shrinks until a player gains roughly 10 points for a win vs an equally rated opponent. If you stop playing for a whole year, for example, this multiplier would again be really high for you.

A quick and easy way to know what the approximate adjustment will be is with this kind of table.

Basically you take the percentage as a decimal (in the H or L column) and multiply by 20, and that's how much your rating is adjusted. The number 20 is roughly the universal multiplier I mention in the first post.

Rating diff is difference between the two player's ratings.
H is % of points the higher rated player is expected to win in a match (wins are 1 and draws are 0.5 notice if only 1 game is played, and you win it, you've won 100% of the possible points)
L is % of points the lower rated player is expected to win in that same match.

So for example lets say you beat someone rated 200 points higher than you. As the lower rated player you were expected to get 24% and you actually got 100%. The difference is 76% so you'll earn .76*20= ~15.2 rating points if your RD is low.

Lets say you draw someone rated 150 points lower than you. As the higher rated player you're expected to get 70% and you actually got 50%. The difference is -20% so your rating is adjusted -0.20*20= -4 points if your RD is low.

poodle_noodle do you know if that's calculated before the match begins (like in "live" games), or when the match ends?

Diamond members have a 2x rating point multiplier

I won a match and I earn zero point!

My rating is 1618 and opponent's rating was 385.

It was a team match.

But zero point, really?

Correct. If you vastly outrate your opponent you don't get any points for winning.

@Martin_Sthal, in a team match you don't have choice to choose opponent. So I was paired with this very low rated player. It should be a principle that a win should earn at least one point and a loss should deduct at least one point. There is some respect in winning.
