Gameplay and Optimal Strategy

Dealer’s first card is first dealt up, at this point, before seeing own first card, player has an option to double his betsize – “Double Attack”. Take this option always when dealer shows 2-8. Do not take this option if dealer has 9-A.

Unlike in regular blackjack, buying insurance is sometimes favorable. Take insurance, if no face cards (J-K) are showing. For example, take insurance if you have 6,8 versus A, but not if you have Q,7 vs A.
