Just play solid and tight in the 200NL game there. They're not smarter. Just the same bunch of retards you find in 100NL. You got real unlucky in all of those hands. But you did lose about as little as you could have.
The only guy I might keep an eye on is HamChoppedUp. He's the only name that I recognize as being decent, but still very basic. I'm sure you've run into him at the 100NL tables. All the regulars at 200NL are the same guys at 100NL. It's the same game.
