The whole point of the rating system is to match you with someone of roughly equal ability. If you do improve then you will be matched against better players, and should lose as often as you win.
The only way round this is to keep improving. If you can figure out how to do this, please let me know.
I enjoy chess but I don't like playing games where I can't actually win in the long run. I might be willing to actually study, but even if I do study I won't be able to win significantly more often because of the rating system. Is there a way around this?
