Dealer Hole-Card and No-Hole-Card Rules
Compare blackjack dealer procedures, including peek and no-hole-card rules, and see how settlement details change strategy and expected value.
Peek game
When the dealer checks under an ace or ten before player decisions, doubles and splits are not exposed to a later discovered natural.
No-hole-card exposure
In some procedures the dealer receives the second card after player action. If all wagers lose to a later blackjack, strategy and edge differ materially.
Table check
Ask whether only the original wager loses or all split/double wagers lose. Labels such as European blackjack do not always answer the settlement question.
Why procedure belongs in the model
Peek games generally determine whether the dealer has blackjack before players add substantial action. In a no-hole-card procedure, doubles and splits may already be on the table when dealer blackjack is discovered. The loss treatment of that extra action is therefore mathematically important.
Questions for the table
Does the dealer take a hole card? If not, does dealer blackjack take every wager or only the original wager? Is the rule different when the dealer shows an ace versus a ten-value card?
Strategy consequence
Do not apply a chart labeled only by deck count and soft-17 rule when the hole-card procedure differs. Match procedure and loss treatment before using double or split decisions near the affected boundaries.
