Mr Blackjack explains the essential mathematics behind card counting and how it can help you win more at 21.
When combined with basic strategy, card counting in blackjack gives players a 1% edge. Some casinos beat card counters through various ploys to reduce this edge though, as we discuss later this season.
Card counting can be profitable if players combine it with other skills and games with advantageous conditions for them. When paired with basic strategy and blackjack deviations, card counting can help players capitalize on their advantage. Choosing blackjack games with liberal rules and ones where the dealers hand-shuffle the deck or play the whole shoe can also make card counting profitable.
The Hi-Lo system is the easiest system for new card counters to learn.
Card counters go to great lengths to hide their ability, but sometimes you can spot the signs. One indication is when a player increases their bet sizes towards the end of the shoe. Another sign is when a player increases their wagers when several low-value cards come out of the shoe.
Card counting systems vary in difficulty. Hi-Lo is the easiest to learn, but still requires a good memory and speedy calculations. Other counting systems, like Omega and Wong Halves, are more complex and difficult to master.
Counting cards is an essential skill for professional blackjack players. Combining counting with basic strategy and bet spreading helps them get an edge over the casino.
Dealers don’t need to count cards. The blackjack odds are already in the casino’s favor in the game, so dealers only have to worry about taking bets and dealing cards.
