The United States has several long-running open tournaments that draw large fields and players of all levels. Five well-known ones are the US Open, the World Open, the National Open, the Chicago Open and the Foxwoods Open. Dates, locations, entry fees and section formats change, so confirm them on each organizer’s page.
Five Events to Know
- US Open: a long-running national championship event run by the national federation. It is typically played over about nine days with a flexible schedule option.
- World Open: a large multi-section event that has traditionally been held around the summer holiday period and attracts many players.
- National Open: a large event in Las Vegas that has been a regular on the calendar for years.
- Chicago Open: a well-known event in the Chicago area, often played over a holiday weekend.
- Foxwoods Open: a tournament held at a casino resort in Connecticut that draws players from the Northeast.
Which events count as the largest can shift from year to year, so treat this as a list of well-known names rather than a ranking.
Why Play a Big Open
- Sections by strength mean you usually face players near your level.
- Large fields give you a chance to meet strong players and visiting masters.
- Side events such as blitz and lectures add variety.
- Playing in a big event is a memorable experience, even if you do not win a prize.
How to Choose an Event
- Check the section list and confirm which one you qualify for.
- Compare the schedule options. Some events offer a shorter or faster path for players with limited time.
- Look at the time controls, since longer games need more stamina.
- Add up travel, hotel and entry costs before you commit.
- Check whether a membership in the national federation is required.
How to Prepare
Play some slower games ahead of time so you are used to long sessions. Plan meals and short walks between rounds so you stay focused. Bring a pen, a water bottle and a notation sheet or app that is allowed at the event. Read the tournament rules about electronic devices before you arrive.
What to Expect on the Day
Expect a busy playing hall, a posted pairing list before each round and a clock at every board. Arrive early, find your table and check that your name and section are correct. After each game, report the result to the arbiter and then leave the table so others can use it. Between rounds, many players analyze their games in the corridor or at a nearby cafe, which is half the fun of a big event.
