OTB tourney or online one?
First Tourney tomorrow!!
Its in real life... If you still want details: http://www.rgvtxchess.org/e107_files/public/2011events/MCCChick.pdf
You'll do fine. The nerves are normal...and may even affect your game. Just go with the flow
Your second tourney will give you a better idea of where you're at
Maby you should'nt play chess this evening before, just watch a movie, and get alot of sleep. Its a good idea to relax before the games start. And eat alot of good breakfast.
First, congratulations for having the guts to try the real thing. Not everybody playing online can boast the same achievement as you ! 
Second, just have a good night sleep and try to focus at the board. Whataver your result, it should be a fantastic experience for you - enjoy ! 
Get plenty of rest, exercise the next day, practice your strategies and tactics and go kick some butt!
Good luck in your first tourn. i have been playing OTB chess for over 30 years and still get a little nervous before a tournament I would say most people do just try to relax and play chess.
Hey guys, Thanks for the advice. I got fourth place :). I totally blundered in the opening on the second game. But besides that I played really well. :D
Well my first tourney is tomorrow and I'm pretty nervous. I'm not afraid to lose, I know its a part of the game, but I just feel a little jittery. So, do you guys have any first tourney advice? :DDDD
EDIT: The tourney is in real life OTB. :D
