Practice your best strategy. In theory, a Blackjack player will increase their bet when the card count is high and decrease it when it is low. 2 to 6 add one. 10 or face minus one.
General Rules for 3:2 Blackjack: Dealer will draw on soft 17 and stand on hard 17. Split any two cards of the same value for up to four hands maximum. Aces can only be split once and will be dealt one card only to each Ace. Doubling Down is allowed on any two cards except Split Aces and Blackjack. Splitting and Doubling Down will require an additional bet amount equal to the current bet. An Insurance Bet is half the current bet and pays 2 to 1.
