Blackjack: questions and answers

Short answers to the questions people ask most about Blackjack. Everything else is in the full rules.

What is an ace worth in blackjack?
Eleven, unless that would take your hand over 21, in which case it counts one. It changes by itself as you draw. A hand where the ace still counts eleven is called soft, because the next card cannot bust it.
What does a blackjack pay?
An ace and a ten-value card as your first two cards pay three to two, so a bet of 10 wins 15. Every other winning hand is paid even money. Some tables pay six to five for a blackjack instead, and that one change costs a player more than most mistakes do.
When should you hit and when should you stand?
Always stand on 17 or more, and always hit on 11 or less. With 13 to 16, stand when the dealer shows a 2 to 6 and hit when they show 7 or higher. With 12, stand only against a 4, 5 or 6. The dealer's face-up card decides it, because a dealer showing a low card is the one most likely to bust.
Can you split any pair?
Any two cards of the same rank. You put up a second bet as large as the first and play the two cards as separate hands. Always split aces and eights, and never split tens or fives. An ace and a ten made after a split counts as 21, not as a blackjack.
When should you double down?
On 11 against any dealer card below an ace, and on 10 against anything up to a nine. Doubling doubles the bet and gives you exactly one more card, so it belongs to the moments when you are most likely to beat the dealer.
Should you take insurance?
No. Insurance is a side bet of half your stake that the dealer's hidden card is worth ten. It pays two to one, which would break even only if a third of the cards were tens — and fewer than a third of them are, so over time it loses.
What happens on a tie with the dealer?
It is a push: nobody wins and your bet comes back to you. The exception is a bust — go over 21 and you lose straight away, even if the dealer busts afterwards. That order of play is where the house edge comes from.
Does the dealer hit on soft 17?
It depends on the table, and the table says which. Some dealers stand on every 17; others draw to a soft 17, such as an ace and a six. Standing on soft 17 is slightly better for the player.
