Despite the fact that not all online casinos will allow you to double on “any two” (blackjack standard rules allow to double when player has 9, 10 or 11), you should double every time you have the possibility to do so. Some casinos even allow making double after you split the cards; you also should take an advantage and just double.
OK, see how it works when you are in play.
You were dealt two cards, and you are given the possibility to make Double Down. To do this in right situation, check the following conditions:
- You have 10, and the dealer has 9;
- You have 11, and the dealer has 10;
- You do not have anything, and the dealer has 2, 3, 4, 5 or 6.
If one of these conditions is true – you must consider dealer is in the “weak” position and you more likely to win.
For those who just started to play blackjack: maybe you will be a bit confused and do not want to bet much, but keep in mind that it’s not right decision. All you have to do is follow the rules and do not forget about probabilities, which were calculated long time ago. Good luck!
