See the dealer's up-card first, then decide whether to double your bet.
Varies Wikipedia gives no figure. The removed 10s and even-money blackjack favour the house; the double attack wager, surrender at any time and liberal splitting give back part of it.
Double Attack Blackjack is an Atlantic City variant built on Spanish 21. It is dealt from eight 48-card Spanish decks — standard decks with the four 10s removed — and pays only even money on a blackjack.
Its signature rule gives the game its name: after seeing the dealer's up-card, you may double your initial wager before your hand is played. Weak dealer card showing? You can put more money on the table before a single decision.
The rest of the rules are liberal: you may double or surrender at any point in the hand, re-split non-Ace pairs up to four times, and double after splitting.
