IM and GM are not awarded by rating and do not approximately equate to any particular ratings. Those titles are awarded by 3 good performances ("norms") in tournaments each, with strict rules about what tournaments qualify. It's common for a 2400+ player not to have an IM title. To get the titles special tournaments are often set up designed to give the players a chance to get a norm if they do well. If you let any low rated players in, it lowers your chances a lot. It doesn't matter if you win 100% of the time against the lower players, it still prevents you from getting a title because chess "performance ratings" are calculated by an average of your opponent's ratings (modified +400 if you beat them and -400 if you lost). Also, ratings are not a linear thing. Going from 1500 to 2000 is WAY easier than going from 2400 to 2500. When you do percentage based interest, you're making it easier to go up when you're at a higher rating, which is the wrong way round. (I have several GM and IM friends who have organized this kind of tournament.)

> IM and GM are not awarded by rating Correct. That's why I used phrases like "typically" and "International Master level". The mentioned ratings are part of the requirements, and are STRONGLY associated with those titles. "The requirements for becoming a Grandmaster are somewhat complex. A player must have an Elo rating of at least 2500 at one time (although they need not maintain this level to keep the title). A rating of 2400 or higher is required to become an International Master. In addition, at least two favorable results (called norms) in tournaments involving other Grandmasters, including some from countries other than the applicant's, are usually required before FIDE will confer the title on a player. There are other milestones a player can achieve to get the title, such as winning the Women's World Championship, the World Junior Championship, or the World Senior Championship. Current regulations may be found in the FIDE Handbook.[12" http://en.wikipedia.org/wiki/Grandmaster_%28chess%29 http://en.wikipedia.org/wiki/Grandmaster_%28chess%29 http://www.fide.com/fide/handbook.html?id=58&view=article http://www.fide.com/fide/handbook.html?id=58&view=articl... For a National Master (depends on country), here is the USCF: "The United States Chess Federation (USCF) awards the Title of National Master to anyone who achieves a USCF rating of 2200, and the title of Senior Master to anyone who achieves a USCF rating of 2400." http://en.wikipedia.org/wiki/Chess_master http://en.wikipedia.org/wiki/Chess_master A computer playing at well above 2500 can be said to be playing at Grandmaster level, despite not filing the paperwork for officially conferring the title. > When you do percentage based interest, you're making it easier to go up when you're at a higher rating, which is the wrong way round. Compound interest is obviously an oversimplification for learning, which everyone already knows is not a linear process. It's illustrative, however, of the vital point: small differences in a feedback cycle accumulate over time into a much larger absolute difference.
