If you want to make money playing blackjack, then you absolutely must take advantage of advantageous situations. When it comes to the game of blackjack, the most advantageous situations you will find are opportunities to double down. When the house edge is reduced, you must attack. When you’re hitting your double downs, you will have a chance at making a killing at the blackjack table.
The most common rule is to always double down with 11 unless the dealer is showing an ace. Some blackjack players disagree with this strategy, but we feel it’s better to attack than to play timid. If you’re going to go for a monster session, then why not go for it all?
One basic strategy that is never debated is to always double down on 10 or 11 when the dealer is showing a 4, 5 or 6. Some players will even double down when the dealer is showing a 3 or a 2. Whether you should take that approach or not will have a lot to do your risk tolerance.
Here is a double down chart that you can refer to for future reference:
2 = Bust Percentage 35%
3 = 37%
4 = 40%
5 = 42%
6 = 42%
7 = 26%
8 = 24%
9 = 23%
10 = 23%
Ace = 17%
These might not seem like great odds, but keep in mind that you can also win the hand without the dealer busting.
