Even if they don’t know much else about casinos, a lot of people know that blackjack has the best odds in the casino. That is excluding poker, of course, since the player versus player format makes it impossible to determine your odds. Just because blackjack has good odds doesn’t mean you can jump in, not knowing what you’re doing, and expect to make money.
If you follow blackjack basic strategy, you can reduce the house edge to only 0.5%. That means that out of every $200 you wager on blackjack, you would have $199 returned to you in winnings, with the casino only keeping $1. That is the average, of course, with streaks making short term results higher or lower. That is following basic strategy, though. If you don’t follow any strategy, the odds will be considerably worse and may end up not being any better than your average slot machine.
That is why it is so important to learn blackjack basic strategy. There is no excuse for not learning it, because the strategy isn’t difficult and is easy to find. A quick search on Google.com for “blackjack basic strategy” should turn up a strategy chart that you can use to learn and memorize the right strategy. The strategy is based on the mathematical odds you have in each situation and in the long run each of the decisions it has you make will be the best move for you. If you do not have the strategy memorized and want to play, look at the chart while you play. There is nothing stopping you from doing that online and you can take as much time as you want. In fact, you can use a chart even at most brick and mortar casinos as long as you aren’t too slow because of it.
