While it is true that blackjack is a gambling game and that you stand a chance of losing money, blackjack is one of the casino games in which players have a decent shot at making some money playing. But there are do’s and do not’s when trying to turn a profit with blackjack, be it online blackjack or blackjack in a brick and mortar casino.
First of the do’s is to play with a blackjack strategy, preferably using basic strategy. Blackjack for real money is not a guessing game. Guessing or “intuitive” playing is a quick way to lose your bankroll. Also, when I say strategy I do not mean some pseudo strategy. Strategy for blackjack has to be based on math, on numbers, statistics and odds. That is what makes something as simple as basic strategy so effective.
Basic strategy is simple a chart with the best statistical play for every hand in blackjack against any of the dealer up cards. It is a simple way to play out every hand while being effective. Playing blackjack according to basic strategy can lower the house edge to 0.5%.
Now it is time for a do not. Do not ever (and I do mean not ever) take insurance. Or play in a blackjack variation with a side bet. Side bets are another way for the house to very quickly swipe your bankroll out from under you. Understand this: insurance and side bets do not have player favorable odds. That is why they should be avoided. Stick to standard blackjack games. And no insurance!
