I have recently aquired the skill of counting (Hi/Lo) and have recently discovered indexes and how to use them (mainly studying illustrious 18) but I am confused about the idea of buying insurance at =>3. Am I supposed to do this every time no matter what my hand is or only when I have a decent hand? I tried this procedure the other night and lost both my insurance and my crappy hands over and over it seemed like. I know one night is no way to base anything off of, but it just seems odd to insure a cruddy hand against and Ace. Any info would be appreciated.
