1. Double Down on a Hard 11
Doubling your bet in situations that are to your advantage will keep the house edge as low as it can be – and it might just earn you a nifty sum in the process! When you hit a hard total of 11, double down against any dealer upcard unless it’s an ace. Additionally, if you have a hard 10, double down against any dealer upcard except an ace or 10-value card.
