Player Strategy – Reading the table

Look up the players hand total along the left vertical edge and the dealer’s ‘up card’ along the top to see the decision the player will make.

  • For the player’s total a 10 and a 6 (16) are considered the same as a 6, 5, 3 and a 2 (16)
  • A7 means an Ace and card(s) totaling 7, eg an Ace and 7 or an Ace, 2 and 5
  • When a hand has an Ace and further cards totaling more than 10, the Ace must count as 1 and the total with the Ace as 1 is used. For example, an Ace, 6 and 8 is considered to be 15 (not A14)

Player has 10 and 6 (16), dealer has 7. Player action = HPlayer hits
Player has 10, 6 and 3 (19), dealer has 7. Player action = SPlayer stands
Player has Ace and 7 (A7), dealer has 7. Player action = H4Player stands as they have 2 cards
Player has Ace, 2, 3 and 2 (A7), dealer has 7. Player action = H4 – Player hits as they have 4 cards

Dealer Strategy

As with standard blackjack, the dealer will hit on all 16 or below and stand on all 17 or higher including ‘soft’ 17 (A6)
