Playing blackjack with hands comprising an Ace is a particular case since we should not be carried away by the emotion.
Suppose our hand is A-2 or A-3, A-4 or A-5. What we should do is to observe the dealer’s card and if the value of this card is between 4 and 6, we should double (since there is a possibility of passing and losing). Otherwise, we should request another card and keep on betting. In the case you have an A-6, you should request another card unless the dealer has a 4, 5 or 6 in which case you should double your bet again.
With an A-7 you should play carefully: double between 3 and 6, stand with 2,7,8 or an Ace, you should request only with a 9 or 10. Pay the maximum attention to this hand since it may be confusing. Try to remember all these pieces of advice to be able to improve the intuition and the response in each hand.
