When you “double up” in blackjack, you are essentially betting the same amount again. This is done by placing two equal bets, either on the first or second card of the next hand.
Some people believe that doubling up is a bad strategy because the odds of getting a natural (aces, 2s, 3s, 4s and 5s) are already very good. By doubling up, you are increasing your chances of getting a poor hand, such as an ace or two.
Others believe that doubling up can be a good strategy if you are playing with someone who is very aggressive and tends to bet big. By betting two times the amount of your original bet, you will likely be able to get the player in front of you to fold more often.
The bottom line is that whether or not to double up in blackjack is a personal decision. If you are comfortable with the odds and want to take more risks, then doubling up may be a good strategy for you.
If you are more conservative and want to minimize your risks, then it may not be the best idea to double up.
