Has the USCF changed their rating system over the years? I'm a solid 1500 player in 30 min rapid. I'm 72, play chess for fun and to escape the humdrum, but in my college days when I took chess much more seriously, I was in the 1900-2000 range in OTB games. This is clearly not my strength now. I have no interest trying to regain this OTB rating. It seems, based on topics here, that achieving higher ratings in OTB would require a much more significant amount of effort than I I ever put into the game. Has the way games rated changed, or are current tournament players much more knowledgeable and prepared than I ever was?
