From my experience with 400NL 6-max, I'm finding that floating is much more frequently done than at 200NL. I think the first two hands are clear examples of punishing floaters. The last two hands where I was minraised, I thought there was a good chance that they were weak, and decided to put the pressure back on them. G00t?
