Blackjack has some unique names for the hands that can be dealt. The first type of hand is the hard hand. This type of hand is basically any hand that doesn't have an Ace in it, or a hand in which the Ace is played so that it doesn't count as the typical 11 points.
Soft hands are then defined as hands that do contain an Ace card. A soft hand is more beneficial, of course, but has a separate way to be played when compared to playing a hard hand. Finally, a stiff hand is a hand that is on the verge of going over the 21 point mark. This means that they have the highest risk of going over, or busting.
If you are given a hard hand, it is best to assume that the dealer has a 10 point card. The reason why this is a safe bet is because there are three face cards in each deck, each of them worth 10 points. On top of that, you get the actual ten cards too.
Of course, the best way to increase your odds is to count cards. This strategy will help you be aware of what cards are left along with what card you may get if you take a hit. Regardless of what you do or how you play, make sure you are confident with your choice. Know how to play your hands so that you can adjust your style accordingly.
