You can Google search Blackjack Cheat Sheet and print one off. I would stay with playing regular blackjack and not play in the tournament. You can learn a lot more from other players and it is more fun. Also remember that you can always ask the dealers advise. Remember that the dealer is working for tips and wants you to win. Some people forget that.
One other thing always play the same way. If you hit a 15 or 16 because the dealer has a 10 showing, then always do it. Do not try and guess what the dealer has. Always consider that the dealers down card is a 10. Of course it will not be every time but the is the way you should play it.
