Blackjack Strategy When Playing a Hard 8 or Less
Hit: Always hit when you have a hard 8 or a hard hand total less than 8.
Why to hit on a hard 8
Because the objective is to get 21, the highest card you could hit would be an 11, which would not make you bust. Recall the most important blackjack strategy: there are more tens in play than any other card, therefore your chances of getting a ten is better than any other card so you are more likely to get an 18, which is decent if you have a hard 8, but not a powerful hand yet.
Keep in mind that a hard 6 is the worst possibly hard hand you can get in blackjack. The reason is if you hit and get a ten, you then have a 16. The dealer can stand on 17 so that is the worst combination. Also, if you try hitting again, you will likely bust with another ten and get a 26.
