In this video, we learn how to count cards in Blackjack. In blackjack, the cards 2-6 are counted as plus one. Seven through nine are counted as plus 0 and the rest are counted as plus zero. What this means, is if you have two cards, they can cancel each other out depending on what "plus" they are. The counts that are minus one will give the edge to the casino, not to you. You want the edge to be a plus, because this means there are higher cards that are in the deck. Simply look at the counts as you keep playing, then you can learn if you need to hit or fold.
