raz, can I offer you some advise?
Before you enter a casino to play any form of poker do yourself a favor. Buy a book written by a poker champion, sit down and read it. I read about 8 of them.
Playing in a casino is not like playing a home game.
Many sharks out there wanting your money.
Pay attention to the section that tells you what cards to play when they are first dealt. You won't always get them but when you do, then you play. Patience is the name of the game.
To give you an example in hold'em, everybody gets two cards down. If I remember correctly there are 169 possible combinations with the first two cards dealt down and out of 169 only 15 are playable depending on whose book you read.
Read a book and thank me later. Be prepared when you play.
About midnight here, time to crash.
