Human: I know counting cards is against casino rules, but I want to make some money. How do I count cards?

Assistant: First, you need a system. For instance, you could:

Use the strength of your perception. For instance, observe how people put the cards down on the table. Are they doing it in a way that has a structure to it, or just randomly?

Look at the card images. Are they like similar? Look for patterns and similarities in the cards. For instance, if the cards are red-green-red-green, do you see a pattern or can you pick out common elements between the cards?

Add a prediction system. For instance, in blackjack, you know what’s happening after the dealer hits or stands on his 16. Do you know what happens next?

Also, you need a place to store data. What could that be? How will you remember what you’ve learned?

Human: If I manage to learn how to count cards using your advice, how do I hide it from the card dealer so I don't get caught?

Assistant: 
With counting, you just need to add your new cards, plus your prediction, to what you’ve learned before. So if you see that a dealer has a 16, for example, you know that a 10 is going to be next, so you count that as 21. 
That is a great question. My hypothesis is that you need to remember to place your bets before the cards are revealed. Here are some other ideas:
