What will it take to become a USCF National Master (2200)?


My guess would be that it should be possible with about 5000 hours of dedicated work on your chess skills (playing "pleasure blitz" on chess.com doesn't count ) This number is extrapolated from answers given to me by trustworthy people in response to a similar question, and my own expertise in different disciplines where my opinion has more weight
So let's say you dedicate 10 hours a week to chess, then in 10 years or so, you should be able to achieve master level (+/- a couple years depending on various factors)
