On the surface, a dealer hitting on a soft 17 does not sound like too bad of a house rule. In theory a dealer who has to hit on a soft 17 because the house rule makes me would be more likely to bust. But that is why it is a theory.

In reality the dealer is actually less likely to bust overall. The reason for this is that Ace. The Ace that is a friend to a blackjack player can also hurt when the dealer can hit on a soft 17. The dealer can reduce an Ace from 11 to 1 just as a blackjack player can. And because of that, the dealer has the chance to rebuild his hand to a stronger one.

For example, if the dealer has an Ace/6 he would have to hit. Let’s say that he hits and gets an 8. The Ace has to be reduced to 1, and he now has a hard 15, which he hits. If he receives anything less than a 7 he is still in the game. And there are more cards less than 7 than there are greater than.

It is because of the dealer’s increased chances of rebuilding his hand to be a stronger one that the house’s rule of a dealer hitting a soft 17 increases the house’s edge by 0.2%. That is a decent sized increase to the house’s edge. Which is why you should avoid any online blackjack games that allow the dealer to hit on a soft 17.

A good many players will play this hand as if it were a hard 17. And while a 17 has the potential to be a relatively strong blackjack hand, playing a soft hand like its hard counterpart is not always the most advantageous why to play it.

The Ace that makes a soft hand what it is creates a whole other way to play. This is why basic strategy has a different way to play soft hands.

But the first thing that you need to know is that a soft 17 is not the same as a hard 17. It gives you flexibility.

Let’s say that you have been dealt a soft 17. And we are going to assume, like a serious blackjack player should, that the dealer’s hole card is a 10—that is the worst case scenario. If the dealer’s up card is an 8, 9, 10 or Ace, you would normally be stuck if you had a hard 17. But a soft 17 allows you to switch to a more defensive strategy.

With the Ace’s ability to serve as a 1 or an 11, you can reduce a soft 17 to a hard 7 and hit. This is giving you another chance to build a stronger hand. You might be able to hit to a hard 18 or more, and give yourself a bit of a better leg to stand on. At any rate, it is better than simply playing a soft 17 like a hard 17.

In fact, hitting is what basic strategy advises. It also advises to take further advantage of a soft 17 by doubling down against a dealer’s up card of 3, 4, 5 or 6. That is when the dealer has the greatest chance of busting, and your strategy should put you in place to take advantage of it.
