How does card counting help in Blackjack?
Considering that most casinos now use four or more decks of cards for a Blackjack game you’d have to be really sharp to be able to keep track of at least 208 cards. The only thing that card counting could do in such a case would be to give you an idea as to how many big or small cards are left in the shoe, which in turn could help you decide whether to take a hit or not. Just don’t get caught, casinos do not like card counters.
