Never worry about ratings, they're the kind of things that drag our potential down. In fact, I have only learned something or amazed myself playing against a stronger player. If you have to get a sticky note or something and cover the rating then do it. And never in your entire life think that if somebody's rating is lower that you try less or see an amazing response to your move but you still do the move because they won't see the response. I've for sure done this before when I offered a draw against a stronger play and they accept then they say I could've won, DON'T OFFER A DRAW JUST THINKING ABOUT RATING. I hope this little paragraph helped some people so have a nice day!
