In European Blackjack the dealer deals their first card face up, but doesn’t deal or consult their second card until after the player or players have played their hands. In the American version, the dealer deals a ‘hole card’ at the same time as their first, face-up card, and this is initially left face down before being turned over once players’ hands have been played.
The only exception to this is in the following situation. The player is offered the chance to take the insurance side bet if the dealer’s up card is an ace in both European Blackjack and under American rules. In the US form of the game, the dealer then peeks at their hole card, to see if they have blackjack.
If they do, the insurance bet is paid out and all other bets are lost, unless the player also has a natural blackjack, in which case their hand is a ‘push’ (a draw) and their stake is returned. The dealer doesn’t peek in European Blackjack and instead allows the players’ hands to play out to conclusion before checking for blackjack. (資料來源)
