Thanks for the quick answer.

We have played three games. The first two he won. So I lost points. Clear. But
then in the third, BTW I had a clear win in a brilliant game, what else did you
expect, I got a draw in the end. And then I told you what happened. You know I
went into my profile then his. And there I could see how I lost and then gotr
the 6 points for the draw. But he got 11 points. I don't know what it is but I
know what I have seen. But - I also saw other things I couldn't understand.
Perhaps this automatic is a bit lazy?
