Cards 2 to 10 are valued according to their number. All face cards (Jack, Queen and King) as well as Tens have the value of ten. The value of Aces can be either 1 or 11. The suit of cards doesn’t matter in Blackjack. The value of the ace seems to confuse some players under the "heat of the action". Player chooses the value for Aces himself. You can count the ace as eleven until a count of eleven will put your hand over twenty-one, then you can count the ace as one.
