The pro Blackjack gamers you see on TV racking up the millions did not get there by accident or through luck. They reached the top of the mountain by climbing it, one step at a time. You too, can get to that level by adhering to the same principles that guided the best players in the world.
The first and most important trait you need to recognize is that winning Blackjack begins and ends with how much knowledge you bring to the table. Don't let the seemingly casual attitude of the pros fool you; every move they make is based on precise calculations.
A winning Blackjack strategy does not consist of trying to get to 21 or praying you don't bust when you draw with a 16; it is much more complex than that. You need to know the differences between hard and soft hands, splitting, re splitting, doubling down, whether or not to take the insurance bet, etc. All of these must be learned because they will all come into play when you are in a casino.
Another factor that will affect the performance of your Blackjack strategy is your reliance on luck. Not just luck per se, but also hunches, intuition and gut feel. Let it be made clear right now: the game is beatable precisely because the mathematical odds and probabilities have shown it to be so. To benefit, you must play according to this criteria.
One reason why people don't like to use odds and probabilities in Blackjack is that it entails a lot of work. Until another method comes up, that is the way it is going to be: winning big payouts require work and effort. You won't be able to memorize all the moves immediately, but provided you practice, you will learn them.
Once you've learned the basic Blackjack strategy, you need to stick to it no matter what. It can be very difficult; if you've won six hands in a row, you might be tempted to draw with a hard 17 because the casino dealer might be holding a 20. Don't. You know the odds aren't in your favor, so ignore that "I'm on a roll and will win" feeling.
Dreams of winning big money in Blackjack need not remain a fantasy. It can, and has come true for those people dedicated enough to spend hours playing the game. If you show that kind of commitment, you'll be a winner too.
