Add here that once you get a big stack, and are past the first few orbits, you can shove damn near any hand. At least a few times, and it is amazing how many will muck purely to the aggression. Then sit low and wait 2 more orbits and do 3 or 4 hands again.
If you have prevailed, you will begin to realize the power of durrrr like play. It is not about the cards, it is about the actions.
