Dont stress
Preparing for a Chess Tournament

Be calm and just remember that either one of you is going to lose and it's okay. I usually like to start a new doc for every tournament I go to making a check list of things like 100 puzzles a day with 20-15 games a day 15 lessons a day and more. I usually like to revise all my openings and tactics the day before. I also like packing some goodies for myself and don't forget to stay hydrated. After the tournament if I did well I usually reward myself with bubble tea. I hope this helps
yall are dumb go ask google
