I find it hard to believe that most people can play at the 1000 level in a few weeks from starting chess.
I played OTB maybe 8 or 9 games between 16 years old and 17 and i lost them all,and i felt really ignorant so i went and bought many books on opening and middle games....maybe 6 books..before i started to play my first OTB game at 16 i already had read a full book tu understand what i was doing.
So when i started to play online around 1999 i already knew a lot.....
And i still bought a lot of books maybe 10 + before i got to 1300....a great book on end game and 4 or 5 on opening....a few on middle game and strategy....
We all do it if a different way......and to get better in the last few years i did thousands of tactical problems...maybe 5 thousands...
I would be curious to see a percentage breakdown of the players on Chess.com. I would bet that most are below 1000
