About the Single Deck Card counting strategy

The card counting is an important strategy in blackjack that yields the best results when used for the single deck version of blackjack. However, the basic principle for single deck blackjack card counting is similar to that for the multi-deck blackjack. This means that the number of high and low-value cards will always be the same.

Choosing a card counting system also requires some adjustments as in many cases, the first two cards you are dealt face down. So, One ideal system for single-deck card counting is the Hi-Op I system in which cards valued 3,4,5,6 count as +1, cards 2,7,8,9, A count as 0, and cards 10, J, Q, K count as -1.  

Therefore, the beginning is usually tough, especially if you are accustomed to other shoe games. However, you need to add or subtract the value of all the visible cards that are dealt on the table. Like this, you’ll have to continue establishing a running count. And this will help you size your bet. However, the troublesome part is the initial face-down cards of other players.  

There can be instances where the counting may become hectic, like when the dealer gets a blackjack and all the players spread their hands face-up. Here your speed and accuracy will be tested as you’ll have to count all the visible cards before the beginning of the next round. And this is something that requires a lot of practice.
