It’s not recommended for novice nor professional players to count cards at casinos. You will get into lots of trouble for doing so.
Counting cards is a system that give you knowing of probability whether or not the next card is a high card or a low card. It’s illegal in all casinos.
In the Midwest of United States, most casinos have their own enforcement that the police cannot touch, because it’s property of Native Americans. So I don’t recommend counting cards at all. This is just probability learning.
There are many basic blackjack card counting system. Personally, I like the Hi-Lo system. It’s simple and fun to learn.
Keep the running count — You can round the running count (Example: from 19 to 20)Approximate the number of decks remaining (watch the decks in a card tray -> determine the decks in the shoe) — You can round the decks remaining ( Example: from 4? up to 5)Divide the running count by the number of decks remaining -> the True CountSubtract 1 from the True Count to determine how many units to betMultiply the Number of Units to bet by the Betting UnitPlay 2 hands and bet that amount per handIf the count result is less than 0, bet as basic blackjack little as you can without drawing too much attention to your bet. Sit out if you can get away with it.Low cards: 2,3,4,5,6 are good when removed — positive count (+1)High cards: 10,J,Q,K,A are bad when removed — negative count (-1)Middle cards: 7,8,9 are neutral so they are worth 0
It’s better when counting at the beginning of the shoe.
Always carry a deck with youRun through the entire deck in your basic blackjack hand while keeping the count, it should come out to zeroDeal cards on the table while keeping the countHave a partner deal to you while trying to play and countTry to play and say and count while the dealer says the card face valuesCOUNT DOWN AND PLAY 3 SHOES IN A ROW WHILE ONLY MAKING 3 COUNTING ERRORS OR LESS WHILE YOUR PARTNER TRIES TO DISTRACT YOUThe Back-Spotter
The Back-Spotter can count cards without even being seated at the blackjack table. When the count gets hot — meaning the house is at a statistical disadvantage — this player will signal for the team’s bettors to swoop in.The Spotter
Acts like a high roller or drunk, making large bets based on the signal from the SpotterThe Spotter counts cards while playing at the table. Casinos screen for counters by watching for dramatic rises or drops in bets — a sure sign that a deck has gone hot or cold. A Spotter avoids detection by resolutely sticking to the minimum bet on each hand. When it’s time to start betting big to take advantage of a favorable deck, he tips off his teammates(True Count is about 3)The Gorilla
The Gorilla doesn’t count at all: He just bets big, all the time. Typically, he adopts the pose of a drunken millionaire who has green to burn. The Spotters ensure the Gorilla’s luck by steering him to tables where he’s got greater than even odds of winning against the house.The Big Player
The Big Player appears to be a type well known to the casinos: the high-rolling recreational gambler who’s content to slowly bleed his money away through hours of competent play. In reality, he’s a Spotter with a Gorilla’s bankroll. He’s not only counting cards, he’s tracking the shuffle for the high cards that rob the house of its advantage. A BP always plays a good deck, so he never has to lower his bets by much.
Pit boss and casino watchers are professionally trained to spot cheaters, and they take any means necessary to ensure that the player knows they are serious.

Always pay attention to the surroundings. Know when to take your win and leave, if you are (even if you are not) counting cards:
The pit boss looks at you and begins scribbling notesThe pit boss starts talking to youThe pit boss intructs the dealer to shuffle up -> Leave quietlyThe pit boss glares at you and then gets on the phone -> LeaveThe pit boss asks you to stop playing blackjack or to leave -> Don’t argue, just leave
