I actually wrote in my profile that I don't care that much about ratings and that I would play anyone.
My approach is that I will try to select games of players close to me, but that I will accept a game from anyone, so I haven't yet used a filter to prohibit lower-rated players from accepting my offer of a game.
I don't particulary WANT to play lower rated players over higher rated players, but I also would like for players higher rated than me to be willing to play me, and if I expect the folks higher than me to pony up and play, I think I should pass the favor forward and let lower rated players play me.
And who knows? They may be on the way up, and I'm really just a small bump in the road on their way to the top!
there are a few players on uchess who make it up to 1300 + but are quite awful n i suspect they must do this... each to there own i guess.
i don't see anything wrong with playing big ratings gaps. i challenge player who are 200 pts + ahead of me every so often.... is good . n nice if they accept even if it is a massacre! also Qh5, or Qf3 is annoying it's not a patzer move i don't think ... can be a pain to deal with. i hate loosing to it.
also noticed it's easier to ' slip ' when u play someone whos not as good in rating ... think there is a psychology in chess where some people play at the strength needed to win.... not the strongest move... making slips more easy ... i've seen over n over people blunder with a peace up ...
