+100 or if I enter a tournament theres no telling
Who do you play in chess?

I try and play +100 to +150.
As chessmaster102 says, in a tournament no telling.
Right now I have games about 80 or 90 below me to almost 500 above me.
I just play the standard things (-300/+300)
Playing stronger opponents is usually good, I think most people will try to play slightly stronger opponents (for example -150/+300 or -50/+200)
I myself struggle against lower rated players mostly, I'm 2100 otb and I hate playing 1600-1900's. I know I should be stronger in a lot of positions, but irl I get a lot of pretty simple positions, where my opponents good moves are obvious.
I have a teammate with 2200 and against higher rated opponents we actually perform about the same (against FM/IM/GM). Main difference is that he just destroys <2000 and I really struggle. He'd score 9/10 and I'd get 6,5/10.
So, that's my reason for playing in the standard range.

It's so annoying when people only want to play people rated higher than themselves. If we all did that that no one could play anyone! I play anyone (who's honest and has some good sportsmanship).
I play anyone who wants to play me. See my page, I have a game against someone 300 points below me. (One of my groups has a tournament that lower players challenge higher players.)
When I challenge, I try and challenge higher players, but I have never, to my knowledge, turned down a lower rated player unless I am at the limit of my games (I try and keep them under 15).
So just a question I was thinking about. For all of you guys who play live chess/online cess whatever you want to call it do you tend to play people with a nearish rating to yours (-50 +50) or do you play people a lot harder then you (+200 min) or a lot softer (-100). Just curious, I play a mixture and win and lose against all, but what can you do..
