"My first OTB tournament is on sunday" ++ Good luck.
"i have some scotch, caro and dutch prepared" ++ Not really useful.
"i am really nervous" ++ That is normal, but there is no need to.
"give me some advice" ++ Play some practice games with the same time control against a strong engine. Spend time outdoor, in fresh air. Sleep well, eat light. Visit the restroom before you play. Do not bring any electronic equipment into the playing area: no cell phone, no watch, no headset... Bring a pen for your score sheet. Use all the time available by the time control. Time is a resource, use it. Always check your intended move is no blunder before you play it.
