Dear Silverdale Chess Club Friends and Families,
 
This Saturday, or TODAY depending  on when you read this, we wiil be  holding our first US Chess, (aka USCF), rated tournament at 12 noon.
 
Four-rounds will be paired according to Swiss System rules at Game 30 (30 minutes-per-side for the entire game), plus a 5-second increment per move.
 
The entry fee is only $5, but there is a “catch.” USCF membership is also required in order to have the event officially rated.
When you consider the cost of a “lift ticket" for a single day of skiing, a ticket to an MLB or NFL event, or other sporting goods, a year-long membership to support USCF is a pretty good deal.
 
The annual dues vary by age group and are required to maintain an active annual membership in the USCF.  Dues include a free, digital copy of the bi-monthly magazines Chess Life and/or Chess for Kids.  For a printed copy of these publication mailed to you, add $12 to the dues below for each.

 
Ages        Annual Dues
 
19-24     $33.00 for one year
 
25-64     $54.00 for one year
 
65+       $48.00 for one year
 
18-Under  $24.00 for one year
 
 
A Word About Chess Ratings 
 
The United States Chess Federation rating system is an essential part of American competitive chess. It provides a standardized measure of a player’s skill level and tracks their progress over time. 
 

The USCF rating system was established in 1950. It was inspired by the ELO system, developed by Hungarian-American physics professor Arpad Elo

Elo’s system, introduced in the 1960s, provided a more dynamic and accurate method for calculating player ratings based on game outcomes. The USCF adopted and adapted this system to suit the needs of American chess, ensuring a fair and reliable measure of players’ performance.

Before Arpad Elo’s innovations, chess ratings were usually subjective not to mention inconsistent. Introducing a mathematical model revolutionized competitive chess by providing a clear and objective method for ranking players.

Over time, the USCF has refined the system and incorporated statistical analysis and feedback from the chess community to improve its accuracy and fairness.

Rating Classes

The USCF rating system categorizes players into various classes based on their ratings:

  • Grandmaster (GM): 2500 and above
  • International Master (IM): 2400-2499
  • National Master (NM): 2200-2399
  • Expert: 2000-2199
  • Class A: 1800-1999
  • Class B: 1600-1799
  • Class C: 1400-1599
  • Class D: 1200-1399
  • Class E: 1000-1199
  • Class F and below: Under 1000
ELO Ratings in other Sports
 
You may be interested to know that the ELO Ratiing system is also being used by other sports, both amateur and professional.
 

American college football used the Elo method as a portion of its Bowl Championship Series rating systems from 1998 to 2013 after which the BCS was replaced by the College Football Playoff. Jeff Sagarin of USA Today publishes team rankings for most American sports, which includes Elo system ratings for college football. The use of rating systems was effectively scrapped with the creation of the College Football Playoff in 2014.


In tennis, the Elo-based Universal Tennis Rating (UTR) rates players on a global scale, regardless of age, gender, or nationality. It is the official rating system of major organizations such as the Intercollegiate Tennis Association and World TeamTennis and is frequently used in segments on the Tennis Channel. The algorithm analyzes more than 8 million match results from over 800,000 tennis players worldwide. On May 8, 2018, Rafael Nadal—having won 46 consecutive sets in clay court matches—had a near-perfect clay UTR of 16.42.
