Counting cards in blackjack is a method used by some gamblers to improve their chances of winning. It is not considered a cheating technique, but it can improve your chances of winning if you use it correctly.
To count cards in blackjack, you first need to know the value of the face cards (10, jack, queen, and king). After you have determined the value of the face cards, you can start counting. When the dealer shows a card, you then add that number to the value of the face cards that you already know. For example, if the dealer shows a 10 and an 8, you would add 1 (the value of the 10) and 2 (the value of the 8) to get 13.
This is how you would continue counting until either the dealer shows a 7 or an Ace (counting backwards from 10). At this point, you would stop counting and would simply play according to whatever hand your count gives you.
