What is a good website to learn how to card count for Blackjack?

You don't need a website to learn how to do that. Take a deck of cards and get a book from the book store about counting cards. If you want some advice, learning how to count cards takes a lot of practise. If you think you are going to beat the casinos, then think again. The funny thing is that the people that wrote those books, wrote the book. The are not earing a living beating casinos. The reason why that is, is because you really can't beat the casinos. They control the game. No casino is going to let a person come in and beat them. They have whole departments called "loss control" that prevents counters from taking large sums of money. You probably could win small sums of money, but then again is it worth the time? If you start winning they will be taking your picture and you will be featured in every casino as a counter. Your winnings will stop real quick. Now you ask how can they do that? It's thier casino, they can even deal you one hand at a time and reshuffle after every hand. See what advantage that gives you.
