Top 3 online casinos with the largest number of slot machines

Blackjack is one of a few casino games where the player can determine his own fortune. This fact makes blackjack a very attractive game as the player can win if he knows how to do it. Throughout the history of blackjack a great number of systems have been invented with the aim of beating the casino. Here we will tell you about the most outstanding strategy.

Blackjack Basic Strategy

One of the main things any player must know before sitting at the table to play blackjack is the basic strategy. This strategy is based on the mathematics of blackjack and has been tested through computer simulations. If the player follows it correctly the house edge is reduced to the minimum. It is the best way to play every possible combination.

Basic strategy is usually given in charts and provides the player with a matrix that shows what to do —hit, stay, double, split, or surrender in any situation. The strategy indicates which decision increases the odds, removing any superstitions.

To get the benefits from the basic strategy, it must be used properly. The decisions are mathematically proven to be the best, and any deviation will decrease players’ winnings—even though, sometimes, a move contrary to the basic strategy works better.

Sequence is important. Based on odds and probabilities the strategy doesn’t guarantee that the player will win all hands. From time to time following the strategy can bring consistent losses, for example, if you stand on 13 against a dealer's 5 and lose three times one after the other, you may want to dismiss this strategy. But in the long run, the likelihood bears itself out: if you stand on 13 against a dealer's 5 a thousand times, more hands will be won than lost.

To reiterate, the basic strategy must be used correctly.

You should use the correct chart according to the number of decks in use. For example, if the chart below were used in a single deck game the house edge would be increased.
