I used to play Blackjack in the casinos, I tend to stay away from it now. One thing I learned was that you need to play the way you are comfortable. If you are play strict basic strategy,there is nothing anyone can say to you. However there are some who will tell you that you are playing wrong in certain situations. These are usually the people who double and split everything. Play your game, and don't listen to the morons with the massive bankrolls.
