About the US National Chess Open:
The NATIONAL OPEN is one of Americaโs longest running premier Open tournaments.ย No tournament in U.S. history was handled with more regard for the comfort and convenience of the players than the first National Open.ย First established by Ed Edmondson in 1965, Fred Gruenberg brought the tournament back to Las Vegas in 1983. He and Alan Losoff organized the National Open for over 25 years and added to its well-deserved reputation asย The Chess Vacation of the Year.ย
Over the years, with additional championships and events, the National Open has grown to become the centerpiece of the Las Vegas International Chess Festival. Alan and Janelle Losoff have organized the tournament since Fred retired in 2009, but he continues to support the tournament as a player and with the โFreddieโ awards for promising players under the age of 15.
The National Open is a 7 round (9 rounds for the Open Section) Swiss System tournament, and players can choose between the standard 4-day or alternate 3-day or 2-day playing schedules. Half-point byes are available for all rounds, with proper notice to the Tournament Directors or with players’ advance entry. The Open, Underย 2300 and Under 2100 Sections are FIDE rated.
