![]() ![]() Overlaying the linear rating scale with the bell curve distribution of players, it is easy to see that the lower rated player has a much easier time improving his rating than a higher rated player. In other words, a 1200 rated player has the same odds of beating a 1400 as a 1800 rated player has beating a 2000. Theoretically and mathematically, a player 200 points higher rated than his opponent is expected to win 3 out of 4 games. Statistically, 5% of rated players reach the Expert (2000) level, and 1% achieve the Master (2200) level. Approximately 70% of rated tournament adult players fall between 1200-1900. The rating distribution of tournament players tends to fall into a normal bell curve distribution about the 1550 mean. ![]() For discussion purposes, let’s say it is 1550. The mean rating for adults is somewhere in the 1500’s. ![]() USCF Standard over-the-board rating scale A good speed chess player will typically have a higher quick rating than his standard rating, and visa-versa for slower players. The tournament player’s USCF Quick Chess rating (G/29 or faster) will usually fall in the same range as his standard over-the-board rating. There are higher levels of Master (SM, IM, and GM), but since less than 1% of all tournament players fall into this range, I will not focus on them here. (Of course, this is based on my subjective opinion as a player and teacher and the players that I polled from various rating levels.)Ī rating is a numerical representation of a player’s approximate playing strength…mathematically based on the last twenty or so rated games played, weighted more heavily toward the most recent results. I will attempt to lay out the USCF over-the-board rating system and set out realistic expectations as a player (hopefully!) moves up the rating scale. ![]()
