Getting a feel for your opponent involves studying where their awareness lies. If they never believe that someone is bluffing, then they probably don't do a lot of it themselves. Also, what your opponent believes you are going to do is probably the same thing he would in your situation, so take note of that. They can play as long as they like without going broke. Practice patience very early in the game so that you play longer than it takes for you to down the drink by your side.
Patience is definitely a virtue when it comes to playing poker.
So when you dive in head first and attempt to guess the playing habits of all eight, you probably won't come up for air. You have to realize that they have only one newcomer to worry about. Be observant, absorb and learn. You can pick up on some of your opponents' tendencies by throwing away a few hands. Remember, you want to win, not win fast .
