How does a tie affects the rating?

Maybe it was discussed in a previous task, but I couldn't find it.
Suppose, that two players with different strength (rating) play against eachother. At the moment it seems that a tie doesn't affect the rating of both players. But normally it is hard enough to get a tie against a stronger player. So shouldn't be there a little bonus in rating for the weaker one?

You are correct, Klaus. A lower-rated player should indeed pick up a few rating points if he/she is able to tie his/her higher-rated opponent. This is logical. I do not know the exact formula used at this site, so I can't say for sure if that is being done here. From what you say it sounds as if it is not. I am a member of the United States Chess Federation and when we play rated chess games, the formula used by the USCF is as you suggest... the higher-rated player actually loses a few rating points and the lower-rated player picks up a few rating points if the lower-rated player ties. (The lower-rated player picks up even MORE points, of course, if the lower-rated player WINS.)

It does work that way here as well, at least it does in my 4 in a row games. After a game ended in a draw yesterday, I lost 7 ratings points while my opponent gained 7 ratings points.

Thanks for your replies. It's good to hear, that the rating calculation works for some games like I believe it should work.

But it doesn't work in my games, where I played a tie.
The last one was a game in a Dvonn tournament. Here is a part of the final message of the game. As you can see, the rating was not changed as expected.

Maybe the calculation depends on the difference between the player's rating or is depends on the kind of game.

The other tie was in a reversi tournament and again, the rating was not changed.

I don't want to get some rating points for these games, no. All I want to discuss is, how should it be handled in future.

My guess is that your ratings didn't change because there wasn't that much difference in your rating and your opponent's to begin with.
I was rated almost 200 points higher than my opponent.

If a rating is calculated out of only a few games, it doesn't change much (or nothing) either. I think the formula only works when there are two established ratings.
