Players often are not aware that the rules of blackjack give them a built boost to their odds. Seriously, it really is there. But in order to turn your blackjack odds and actually benefit from this little boost you have to not be afraid to use it.
I am talking about doubling down. This popular blackjack term gives rise to visions of daring blackjack players doubling their wagers for a one-card shot at beating the dealer. And really that is all that a double down is—a player doubling the amount of their wager and only receiving one more card. This play is often treated as the blackjack equivalent to going all-in in a game of poker after a battle of raises. However, doubling down is not as daring as a poker all-in—mostly because you are not putting all of your money on the line. But doubling your wager just feels more daring.
But because doubling down gives you the opportunity to win twice as much as you normally would in a single round of blackjack, it increases your blackjack odds. In fact, of all the plays that you can make, doubling down is the one that can increase your odds the most.

The key is knowing when those opportunities are. And even that is not as hard as it sounds. All you need is a basic strategy chart. That chart will tell you when the best statistical times to double down are—usually with the hard hands 9, 10 and 11 against certain dealer up cards.
Making double downs at those opportune times is one of the best built in boosts a player has to their blackjack odds.
