You have an ace and a five and you decide to stay (not to take any more cards). If you have an ace and a deuce, that would be either three or thirteen. For example, if you get dealt an ace and a five, the dealer will announce: “six or sixteen”.
In blackjack, an ace is worth either 1 or 11 - the player gets to choose. The only exception would be if you were playing a blackjack side bet where if your first two cards and the dealer’s card are in order and have the same suit (a straight flush), you win. The value of the card is exactly the same. There is no suit order, and it doesn’t matter whether you are dealt, say, a queen of hearts or a queen of clubs. Imagine doing that if each picture card had a different value. This makes it easy for the blackjack dealer (and player) to add up the total score quickly. On the other hand, picture cards - jacks, queens, and kings - count as ten. In other words, in blackjack all number cards (deuce to ten) count as their index. In blackjack, a deuce has a value of two. So - is your score 3 or 13? And if you take a card, and the dealer gives you a ten, do you bust and lose? The dealer points at your two cards and says “three or thirteen”. You are playing blackjack and you are dealt an ace and a deuce.
