There is no one definitive answer to this question, as everyone’s playing style and preferences will be different. However, in general it is generally recommended that you use a full deck of cards for blackjack.
One reason for this is that it increases the chances of hitting a blackjack. When playing with a full deck, the odds of getting a blackjack are approximately 1 in 21.
This means that if you play with a full deck, your chances of winning are significantly higher than if you only use card numbers.
Another reason to use a full deck is that it makes the game more exciting and challenging. When playing with a full deck, there is always the potential for more fun and excitement – as every card can be used to potentially win money.
This makes the game more engaging and enjoyable for both you and your opponent.
