WHY DO YOU GET SO MANY OR LOSE SO MANY RATING POINTS
Ok the one with your win against the 2000+ player I don't really know but it looks like he threw the game on purpose. It might have something to do with accuracy.
Honestly it might be a troll account he seems to play horribly and he lost like 15 games in a row and barely lost anything in terms of rating.
I specifically said I didn't know and it was just a guess. and you forget about the 2nd thing I said.
Ok I have no clue but he didn't play like a 2500+ player at all. You might just be overreacting to a single glitch in the system. There also might be a limit to how much you lose in a game, it'd be stupid if you just rose 200+ because you beat a grandmaster, and same goes for losing if you are a grandmaster.
You should NOT get 200 rating points for beating someone unless you have played less than 100 games.
If you beat a person 1000 points higher does not mean you are as good. It makes perfect sense to gain 16 points. It is basically double the difficulty to beat someone your rating
can you show that game?
