Stop playing immediately. Immediately! DO NOT SET FOOT IN A CASINO! Am I absolutely clear enough? Don't play any more blackjack, because you don't know what you're doing.

Now, do you know perfect basic strategy? Can you tell me, without thinking, when to split 9's, and when to soft double against a 4?
Secondly, do you understand the concept of true counts in hi-lo?
Thirdly, what is the minimum bet you are using, and what is the maximum, and when do you bet the maximum?
