What time is it where you are because if you don't get enough sleep you will be tired for the tourney
i need tips
Sort:
one that works is do NOT go on an empty stomach
try to think ahead a few moves while you can(have a back up or two on hand if your opponent is taking a bit of time deciding on their next move)
if your opponent makes a strange/suspicious look, take a few moments to see what would happen if you react the most obvious way
just a few basic tips. I'm going to one as well tomorrow
Good Luck! 
i have a chess tournament tomorrow and i need some helpful tips.
