If a player’s first two cards are of the same denomination, such as two jacks or two sixes, they may choose to treat them as two separate hands when their turn comes around. The amount of the original bet then goes on one of the cards, and an equal amount must be placed as a bet on the other card. The player first plays the hand to their left by standing or hitting one or more times; only then is the hand to the right played.
The two hands are thus treated separately, and the dealer settles with each on its own merits. With a pair of aces, the player is given one card for each ace and may not draw again.
Also, if a ten-card is dealt to one of these aces, the payoff is equal to the bet (not one and one-half to one, as with a blackjack at any other time). After all the players have completed their hands or gone bust, the dealer reveals his or her down card. Depending on the cards in the dealer’s hand, the blackjack rules at the table will dictate whether the dealer will hit or stand. Each of the good and bad rule affects the basic strategy, some greater than others.
The effect for any one rule, say surrender, may also be slightly different for a double-deck game vs. a six-deck game. If you consult the tables in Chapter 3, I’ve summarized what the house edge is for different number of decks and mix of playing rules. Use this as a guide to determine which mix of rules is the most player favorable. One important aspect of blackjack is “hard” and “soft” hands. These concepts not only affect the rules of when the dealer must hit or stand, but also can also affect the player’s blackjack strategy. Be sure to check the casino rules for more information on hard and soft blackjack hands. https://www.messa.org/wp-content/plugins/wpphp/all_about_blackjack.html
