If a dealer hits a soft 17, you’ll need to double down in order to take advantage of this situation. Instead, look for a table where the dealer stands on all 17’s. If you want to maximize your profits in blackjack, you should avoid playing at tables that make the dealer hit soft 17. While this is not as bad for the dealer as it might sound, it does increase the house edge, which will ultimately cost you money over time. For example, some casinos require dealers to hit soft 17 (hands such as Ace and 6). Many blackjack players are oblivious to the fact that dealer rules can affect how you play a hand.
