This is very good advice.
Tight passive, just rob them blind. They will only play back at you with nuts or near nuts.
When the tension builds and builds, hopefully you will find yourself with a monster hand, and they will make a huge mistake vs. you.
As Loafes said, loose passive, don't bluff. Just bet the ba-jeezes out of your made hands. They will pay you.
