I have been practicing basic strategy in BlackJack, and I have noticed that with every basic strategy chart I find that in terms of hard totals they all stop at 17. Why is this? And if I want to find my best course of action for a hard 18 (Jack, Queen King) and an 8, how would I figure this out? I'm sure there's something I'm certainly, missing, I'm just not sure what it is. Examples:
I am dealt a hard 18, King and 8. Blackjack basic strategy charts don't dictate how do this, why? and how do I figure this out?
I am dealt a hard 19, King and 9. Same questions as last time.
