OTB Chess Rating


Hi NMRhino.
Each chess federation (FIDE and national federations) has different rules for this and they can be complicated. Generally, you will start as officially “unrated” but also have a hidden "provisional rating." Your provisional rating will swing greatly with each game you play while unrated based on your result and the rating of your opponent. After playing a set number of rated games (typically 20 to 30), your provisional rating will become your official rating and it will now change much more slowly.
Best.

If your flag is correct, US Chess has a formula to initialize your rating in your first event, based on your results, the feeds that intialized rating back through the rating formula.
If you really want to know the full details, you can check out the rating document: http://www.glicko.net/ratings/rating.system.pdf

Also here's the U.S. Chess Federation rating estimator. all those empty spaces u see on there are where u enter ur opponents ratings and the total points u scored against them. Pretty easy after u get used to using it a couple of times.
