Before Playing A Major Tournament.
I've seen a few threads asking what to do before playing a tournament. I stumbled across a article written by Daniel Negreanu that has a few tips to bear in mind.
1) Get some sleep.
If you're tired, you'll start to lose focus and you won't spot tells
or betting patterns, especially if the tournament is going to go on for more than two hours.
2) No alcohol.
It's not good for your health or your game.
3) Limit your caffeine.
Caffeine dehydrates you and it makes you feel groggy and it you'll feel even worse the next day. That includes coffee or Red Bull.
4) Watch what you eat.
Avoid foods high in fat becuase it makes you tired and don't overeat. Too much food might make you lethargic.
5) Avoid people.
Being in a large group sharing bad beat stories could wear you down. A discussion with someone you trust is fine but it's best to find a quiet place to think.
