I remember reading a few interviews of players like Kasparov and Kramnik. It seems if you're in a good environment (coaches, strong tournaments) and young and talented it seems to take at least two years.
If you're an adult and have a job, family, and no coach, then it may take 20 years to get to 1600
Hey guys so how fast can someone do this? Just curious, I read somewhere some guy became a master in 5 years. Any tips or personal stories of meteoric uprises; thanks.
