Resignation points

When I resigned my points went up and when my opponent resigned mine went down.

Any ideas why

The game you ended today

Game 10615553

was won by you according to the history...

The rating chart shown in Thread 80000 shows the effect of a win or loss in each game. The number shown is halved whenever there is a provisional player in the game. You often get apparently-odd readings where two games finish at around the same time, but if you check your profile chart the sequence of finishes is shown.

Yes I won but my points went down. Thanks for checking..

Thanks,

He is provisional so maybe that is why.
