Instructions
Sign up for a chess league or local chess club. This will allow you to participate in tournaments in your area. Two of the largest chess leagues are The United States Chess Federation and the World Chess Federation.
Check upcoming events that your chess league is hosting. Look for events that match your skill level and have prizes available to winners. Many events that have prizes are catered toward players of lower skill levels.
Play as many events as you can. It is easy to sign up for an event, but you need to perform well in order to receive prizes. Playing often will increase your skill level and experience.
