The behaviour of the dealer follows a simple pattern: The dealer draws cards until his total is greater than 16, unless he has a “soft 17”, that is, a total of 17 in which one of the cards is an Ace counting as 11 (e.g. an Ace and a 6). If the card drawn when the dealer has a “soft 17” takes the total above 21, the value of the Ace is changed to 1, and the total of the hand recalculated.
