If the player's two-card total is nine, ten or eleven (in some casinos, only ten and eleven, and in some casinos soft 19 and 20 are included) and the player doubles, the player has the option of discarding the double-down card received and replacing it with top (unseen) card from the shoe.

Insurance when dealer has an open Ace is not allowed (depends on casino rules).

Dealer twenty two pushes against any active player hands (depends on casino rules).

The rules for the power blackjack game are based on the standard blackjack rules and involve common blackjack terms.

Interesting to note, Thomas Tullis at also used this table to come up with a strategy for playing blackjack online at Bovada.Power blackjack is a variant of the card gambling game blackjack, modified by certain doubling and splitting rules, called 'Power Double' and 'Power Split,' that are advantageous to the player, offset by the rule that, when the dealer makes a total of twenty two, any active player hands push rather than winning. Why would you consider doubling (2,Ten) vs 3? Well, sometimes in tournament play you’ll need to make unconventional plays to maximize your chance of advancing to the next round.

This chart shows that you can expect to win 36.0% of the time, push 4.9% of the time and lose 59.1% of the time. You could use this chart to see what would happen if you doubled down. Inside each data area of the table, the top line is the percentage chance you’ll win the double (in blue), the middle line is how often you’ll push (in black), and the bottom line is how often you will lose the double (in red).Īs an example of using the charts, say you’re holding (2,Ten) against a dealer upcard of 3. A combinatorial analysis process was used to calculate these numbers. The dealer is assumed to have already peeked under tens and aces and does not have blackjack. The figures quoted are for a 6 deck game where the dealer stands on all 17s. This chart shows exact percentages for how often each double-down hand in blackjack will win, push, or lose.
