Here's what I have done:
a) get plenty of rest, b) eat lightly, so as not to carbo-induce sleepiness, c) review tactical problems to enhance your vision, d) use your time wisely during the game - do not leave the board except for bathroom or nervousness breaks, and e) finally, have fun - after all, it's only a game, and games are supposed to be fun.
Good luck.
Hello everyone and It would be really helpful if anyone told me what they usually do before a OTB tourney. It will be on Tuesday and will be a 3 game round-robin. I will be happy to post the games after. Time controls are 60 minutes for each player. Any advice is welcome.
