first time tournament play - seven stud

[morgan]

Hi, I've been playing 7-stud for a couple of years now, and I am planning on playing in my first tournament in a week. It is a small stakes tournament -- $35 entry (25 towards pot) with optional $20 rebuy. Could someone tell me the most important difference in tourney play as opposed to normal table play? I really don't know anything. Thanks in advance...
