Tournament Strategies
After receiving pocket cards, you are immediately faced with a choice: play your cards and either raise or call the blinds, or fold.
Practice Matters
Once you have yourself in a good mental state
Once you have yourself in a good mental state make sure to have adequate supplies around you including water, snacks, de-stressor tools, money, and a meal/break plan if you're at the casino. You don't want to miss an important hand because you're dying of thirst and could have easily solved it by having an adequate amount of water at your disposal.
Diet
Diet As a poker player you're going to be in a lot of conditions where food and dietary options are pretty poor. I've been in very few casinos that have good food options, but there are some around. The vast majority of food option will be starchy, saturated fats that are heavily processed. Those are not the kinds of food that are going to keep your brain at its peak and your body in the best condition, but a lot of them do taste good!
