Reading how much spoonitnow and others give attention to table selection I have done the same thing. It makes a difference.

So if I'm at a table and a new player starts some funny stuff like playing back against me all the time just to be a bully, I leave. It's that easy. If I'm in the mood I'll nut camp and wait until I can smoke him just to take him down but that's rare because bullies tend to make you play a way you shouldn't just by the way they play against you.
