I know rip was thinking this but he left out the good old position raise w/ marginal hands. Nothing wrong w/ raising AJ, KJ, KQ and medium pocket pairs from middle to late position.

Online with non-observant opponents, you can camp out and play nothing but premium hands and often you will still get action. It seems that you need to find a new venue where people don't have a read on you or start to mix up your play a little.
