People not knowing how to play is the reason the casinos make so much money on BJ. I have been playing for 35 years and believe what the experts post about the potential house advantgage being reduced to about 0.2% for those who play correctly. I know that sitting at $5 tables or less and betting conservatively for hours on end I can visit Las Veggas for 3 or 4 days and be plus or minus $200 every trip. I know that the cocktail waitress gets more business than that from me. That said, there are a lot of players who have no clue or just decide to sit at one of those 6:5 tables.
