I want to ask a question, I think it is ok. I did a search for 21 and found this site. Well, I went to Vegas 2 weekends ago with my friend and played 21 and won about $400. I wanna go back but have become a bit confused. people kept yelling at me when I was playing. Some would tell me to take a card and other times tell me not to take a card. I asked why and they said because the dealer has a whatever. I said how does it matter and they just stared at me. The same thing happened a lot more than once! One guy said love just take a card! I said why! He said the book says so. I said what book? And he said doesn't matter! The dealer was ok because he said just play how I want. Is there a book on how to play this game? Hoping for your help. We are going again pretty soon.
