The numbered cards (2-10) have a numerical value equal to the number printed on the card. Face cards are of the same value, which is 10. Aces can have the value of 1 or 10. The suit of the cars is not take n into account. The value of the ace seems to confuse some players under the "heat of the action". Player chooses the value for Aces himself. Value an Ace as 11 only if in this case your hand doesn’t go over 21.
