How the deal works
In a peek game, the dealer takes two cards, one face down. If the up card is an ace or a 10-value card, the dealer checks underneath for blackjack before anyone acts. If it is there, the hand ends and you lose only your first bet.
In a no hole card game, the dealer takes just one card. Players act first, doubling and splitting as they wish. Then the dealer draws. If the second card gives the dealer blackjack, all bets on the table lose, including any money you added by doubling or splitting.
Some games use OBO, short for original bets only. Under OBO, the dealer takes only your first bet when it has blackjack and returns the extra double or split money. Many Australian games and some online games use this.
Strategy changes without OBO (6 decks)
| Hand | Dealer shows | Peek game | No hole card |
|---|---|---|---|
| Hard 11 | 10 | Double | Hit |
| Hard 11 | Ace | Double or hit | Hit |
| Pair of 8s | 10 | Split | Hit or surrender |
| Pair of 8s | Ace | Split | Hit or surrender |
| Pair of aces | Ace | Split | Hit |
Based on published no hole card charts; check your exact rules.
Why the strategy shifts
With a 10 up, the dealer has blackjack about 1 time in 13. With an ace up it is about 31% in a 6-deck game. Under no hole card rules, doubling or splitting into those cards risks extra money that a blackjack would take.
So you add money less often against a 10 or an ace. A hard 11 against a 10 is still a strong hand, but the chance of losing double to a dealer blackjack tips the choice to hitting. Splitting 8s against a 10 or ace becomes a hit or a surrender if offered.
Against dealer 2 through 9 nothing changes, because the dealer cannot make blackjack from those up cards.

Where you meet it
Most land casinos in Europe and the UK use no hole card rules. In the US, almost all shoe and pitch games peek. Some licensed online and live dealer games in US states follow European rules, so the rules screen is the place to check.
Double exposure, Spanish 21 and other variants may use their own peek rules. Always read the table placard before you play.

Questions before and after you play
A 90-second guide cannot cover every table moment. Tap a group, then a question — answers are short paragraphs, not one-liners.
01Basics
What is no hole card blackjack?
A version where the dealer takes one card at the start and draws the second only after all players act, so it cannot check for blackjack early.
How much does the rule cost?
Without OBO, about 0.11% for a player using the right strategy. With OBO the cost is close to zero.
What does OBO mean?
Original bets only. If the dealer has blackjack, you lose only your first bet and get double and split money back.
02Strategy
Should I double 11 against a 10?
In a no hole card game without OBO, most charts say hit, because a dealer blackjack would take both units.
Should I split 8s against an ace?
Without OBO, most charts say hit or surrender, since a blackjack would take both split bets.
Does anything change against a 6?
No. A dealer 6 cannot make blackjack, so strategy against 2 through 9 stays the same.
03Where
Do US casinos use no hole card?
Rarely. Almost all US tables peek for blackjack. Some online and live dealer games use European rules.
How do I know if a table peeks?
Read the placard or rules screen. Watch whether the dealer takes a face-down card at the start.
Is no hole card used in Australia?
Many Australian casinos use no hole card rules with original bets only, so extra bets are returned on a dealer blackjack.
