"Can an average person ever break 2000?"
I assume you mean over-the-board chess.
The answer is: Yes, Of course!
But you have to REALLY want to do it.
In my case it took me almost 13 years:
My first tournament was March 24, 1996, and I finally reached 2000 when I woke up the morning of December 3, 2008.
Awesome (and well done by the way, that is a great achievement) but do we now at least have some practical evidence that average (I'm not personally calling AH 'average' but he didn't say otherwise) + hardwork can potentially reach 2000 level?
Once again, I'm not knocking the 2000 level, anybody even close to that is incredible in my book, I'm just championing my belief in human potential + hard work and dedication - I maybe open myself the risk of being called hopeful and 'ignorant' in doing so, as in this thread, but I don't give a hamster shit!
Now back on tactics trainer...
Exactly the point I am making: I was definitely NOT a star.
In fact, growing up in New York City, I personally knew (and know) a lot of famous players that played in the same tournaments as I, including Hikaru Nakamura, Fabiano Caruana, Irina Krush, Justin Sarkar, Elina Groberman, and as the years went by Alex Lenderman, Teddy Coleman, Iryna Zenyuk, Robert Hess, Marc Arnold, Salvijus Bercys, etc. ...and those are merely the ones that gained international titles. I knew plenty more 2200-2400 players who were at the top of their age group in the U.S., won multiple National Championships, and made numerous All-America teams but later gave up chess.
I would typically finish in the middle of the table at the big NY scholastic tournaments...I was a mediocre scholastic player who was obsessed with becoming better and increasing my rating.
By the way, don't just stay on Tactics Trainer. Work on strategy too. It is more important than is typically realized...
Wow great stuff. Well you are a star in my book for working so hard and doing so well. I take my hat off to you.
(Your last comment is also very interesting. I have come to the conclusion in the last couple of weeks ((had more time off work to think)) that strategy is also very important and is my weaker aspect vs tactics. I have been going through master games in terms of looking at strategy, in particular with Chernev's Logical Chess book with this in mind. I feel I am doing right by this. Hope so.)
a picture is worth a thousand words. Obama plays chess, I wonder where on the average scale he fits in and what his potential USCF rating would be provided the full measure of his potential...
