Statistically, around 8.0% of the hands dealt to you will be situations on which you should double down on a hard hand.

If that doesn’t encourage you to learn everything about the double down strategies, nothing will. That statistic sounds especially nice since your wager is doubled. The strategy analysis feature of the Masque Blackjack game will show that the doubling down strategy provides a win rate of about six out of ten of the recommended double down hands! This is the mathematical rationale behind doubling down. But if hitting, as opposed to doubling down, can’t double your advantage against the house on a given situation it will pay you to win less often at twice the amount. You would even win more hands if you never doubled down. Wouldn’t it be nice if you could draw another card? Sure it would. Periodically, you will double down and draw a low card. As you will see in the split strategy tables, there are a few additional hand situations where splitting is recommended only when doubling down is allowed after splitting. Sometimes you split to win more, other times you split simply to lose less. You just learned 40% of the split strategy. On the other hand, if you split the fives your odds of ending up with two hands each totaling fifteen is very unattractive. If you don’t split, your odds are reasonably good that you will acquire a hand of twenty on the very next card drawn. There are more tens in the deck than any other card. Pressing your luck, by splitting in these situations, doesn’t make much sense. Two tens make twenty, already a good hand. If you split these, you have a healthy chance of bettering your hand. A pair of eights leaves you with a sixteen, a lousy hand by any measure. And the chances are extraordinarily good that you will end up with some other high hand value if your first card is an ace. Chances are greater than 30%, on the average, that you will end up with a strong 21. The ace is, however, the best card you can have as the first card of your hand. Ever wonder why? A soft twelve (a pair of aces) in itself isn’t anything to write home about.

The Split LogicĪlways split aces and eights, never split tens and fives. Consult the double down strategy tables if no entry is given. *SP* = split only when doubling down is allowed after splitting. Consult draw/stand strategy tables if no entry is given.
