GRADINGS LIST FOR REGISTERED MEMBERS

Listed below are the ECF (English Chess Federation) grades for club members we have registered with the Stockport Chess League. Grades are calculated after each game a player completes in a league match, or from results of games in ECF-registered chess congresses/competitions.

The calculation is as follows: take your opponent's grade and add 50 to it if you won, or substract 50 points from it if you lost (if the game was drawn, use your opponent's grade). However, those calculations assume that your opponent's grade is never more than 40 points above, or below, your grade; so if your grade is only 90 and your opponent's is 150, take his grade to be 130 (90+40) in the calculation of your grade after the game. Similarly, if your grade is 150 and your opponent's 90, take his as 110 (150-40). Your cumulative grade is then the average of all such calculations (minimum of 9 games).

Please note that all current ECF grades are now so-called NEW GRADES calculated by the ECF, which have been adjusted for drift and spread over the years. They have been updated and recalculated by the ECF during the past 2-3 months, and the values shown in the table were taken from the ECF gradings website on September 17th 2009. You can visit this website yourself at http://grading.bcfservices.org.uk/index.php and search by player's name or obtain a listing of any chess club's players.
