When to hold them, when to fold them.

Blackjack is a notoriously popular game with exciting odds. We devise some of the strategies you can use to give yourself an edge in the game.

There are typically 6 golden rules that outline when to hit, stand, split and double down.

  1. Stand on 12 against the dealer’s 6 or lower otherwise the player will hit
  2. Hit on 17 against the dealer’s 7 or higher
  3. Hit on soft 17 or less and stand on soft 18 or more
  4. Always split a pair of Aces or 8’s
  5. Split a pair of 7’s against the dealer’s 7 or less
  6. Double down on 10 or 11 if the card total is higher than the dealer’s up card

One of the most popular blackjack strategies used which indicates when to hit, stand, split or double down , leverages a simple statistical chart.

To use this, you simply need to find the row that corresponds to the value of your hand, then find the column that illustrates the dealers up card. For example, If the player is dealt a 10 and the dealers up card is a 7, the player would double down as shown in the diagram, note that this also respects our #6 golden rule. Another example is if the player has double 5’s, the player would double down unless the dealer has 10 or above.

Edward Thorp, a statistical genius, created a model to derive a simple strategy in blackjack, focusing on the ‘significance’ of each card and its value. His results were outlined in the image below. If two 5’s are removed from a player’s hand, the players advantage would rise by a whopping 1.69%. This model can be used in conjunction with the strategy table and golden rules to achieve a neat competitive edge.
