Is This Tournament a Good Fit?

This three-day Swiss offers sections for players from beginner to master level, with a Championship division for the strongest competitors and separate brackets for those rated under 2000, 1700, 1400, and 1100—so you'll find peers at your skill level. The classical time control (90 minutes plus 30-second increment) gives you time to think through positions carefully, and the reasonable entry fee of $70–100 makes it an accessible choice for serious amateurs. If you're a titled player, you'll compete free of charge while helping strengthen the field.
