Hit or Stand

Dealer's Card is an Ace
This is one of the worstscenarios on the table. What you should consider in blackjack is that a card with a value of 10, which are 10, Jack, Queen, and King, is more likely to appear than any other single card value. In thiscase, the dealer has a blackjack roughly 4/13. Also, the dealer with an Ace has more chances of drawing cards without getting busted. Your approach is to aggressively play the game by trying to get agood hand like a 17 and above, as the dealer is likely to have a strong hand.
Dealer's Card is a 10, J, Q, or K
There is still a 1-in-13 chance that the dealer has a blackjack and a 4-in-13 chanceof a 20. So you need a strong hand to compete. An 11 gives you a good chance of making a 21 with a hit. But you are still in the risk of busting and you should hit 10 or less, hit 12-16, and stand at17+.
Dealer's Card is a 7, 8, or 9
In this scenario, there is a better chance of winning, as the dealer cannot make a blackjack. On the other hand, it's possible that the dealer will get a betterhand like a 17 and above, which is why we need a stronger hand to compete. Nevertheless, both 10 and 11 can give you a better chance of a winning 20 or 21. You will still need to risk busting and youshould hit 9 or less, hit 12-16, and stand at 17+.
Dealer's Card is a 4, 5 or 6
This is not good for the dealer because a bust is very likely to happen. The key is to not get a bust, and it's wise...
