Just recently moved up to NL200. Taking one-pair hands too far?

[xcrack999]

I just moved up to NL200, and I have a feeling that I might be getting too aggressive and backing my stack too often with TPTK or overpairs. Does anyone who just made the transition from Party NL100 to NL200 know what I'm talking about? I'm finding that there are A LOT more LAGs at NL200 than NL100, a lot more people who will raise my continuation bets without anything good, and as a result, I think my playing style has changed. (even against unknowns, which I think might be a bad thing?) Anyway, onto the hand. Villain just sat down about 10 hands ago, so no reads. Comments?
