I know who Tomashevsky is but I have never heard nor read about this Yaakov guy; and I would be willing to bet money (not any amount, just a tiny bit
because I am as bad at poker as I am at chess...) that a lot more players know the top 100 player than some unknown internet screenname.
I also think that internet chess is not "real" chess. Sure, it is fun to sit down at home and play some internet blitz games, but a real game is when you sit down at the board in front of your opponent, shake hands with him and start playing, with a real clock and a sheet etc. It's just a different atmosphere.
Also, I think what curtains says about not playing serious on the internet is completely true. My internet rating is 400 points lower than my Fide rating. This is mainly because I suck at blitz but also due to the fact that they are just fun games and I really don't care if I lose five in a row. If I lost five real, OTB games I'd be depressed for days.
Back to the topic of the thread, it took me 14 years from absolute beginner to reach my highest rating.
