The NATIONAL OPEN is one of America’s longest running premier Open tournaments. National OpenNo tournament in U.S. history was handled with more regard for the comfort and convenience of the players than the first National Open and we are proud to continue the tradition of this National Championship. 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 as The Chess Vacation of the Year. 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 “Freddie” 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 you 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 your advance entry. The Open, Under  2300 and Under 2100 Sections will be FIDE rated. Chess sets and boards are provided for tournament play only, not for skittles.  Please Bring Increment-capable Chess Clocks. Live broadcasts of select games from the National Open, and other events will be available here and on some of our sponsor web sites. Thank you to our many loyal players who keep coming back year after year, for the Chess Event of the Year!

Open section is open to all players. Under sections are open only to players with ratings lower than the section limit. Players with provisional ratings (based on 25 games or fewer) may not win an amount greater than 40% of the top prize in any under section of the National Open; the balance of the prize goes to next players in line.

Players without official ratings may only play in one of the top 2 sections or in one or more Beginner section schedules. Verified foreign ratings may be used if reliable conversion is possible. FIDE ratings are converted by USCF = FIDE + 50 if FIDE >= 2200, USCF = 0.765 x FIDE + 560 if FIDE < 2200.

June FIDE ratings will be used for the Open section, official June US Chess ratings will be used for all other sections. Other ratings, including US Chess online ratings, may be used if higher. If your rating changes in the June supplement you will be moved up automatically or down on request. Players rated more than 100 points higher than the section limit during the last 2 years may be moved to a higher section.

The decision of the chief tournament director regarding eligibility, rating adjustments, conversions, unofficial ratings, the CCA minimum rating list or other rating issues is final.

Every effort will be made to start players in the appropriate section, but if an error is discovered late in the tournament it will be corrected.  If there is any reason you may not be eligible for the section you entered, be sure to ask for a review before Round 1 is paired.
