Where do you get 2100 from? According to this page, the boys U16 minimum is 2300, and U18 is 2400. Good luck with that!
Even assuming 2100 is the goal, I don't think it's possible. I'm in an almost identical situation: my USCF rating is 1762, after less than 3 years of tournament play, and I turned 16 last month. This year has been extremely busy, but I also have DEM and look through it occasionally (I know, I really have to set up a board and look at it).
Put simply, I think 1800 is one of those plateaus that a bunch of people get stuck at. People stop making tactical mistakes. You need to win games instead of just letting your opponent lose them. Do you really think you can be on par with national masters in 7 months? I'd hope so (NM is my ultimate goal), but unless you're gonna drop out of school to study 8 hours a day and go to tournaments every weekend, I think you'll be disappointed.
But we should work together some time.
This is so true. Even strong,child prodegies (like Waitzkin,the Polgar sisters,etc) claimed that they got stuck around for A class for a while. Waitzkin himself says that once he reached 2100,he started losing and it took him a while to finally break off and start winning again.
It's not so much that A class players an experts don't make tactical mistakes,they do. But they are very small innacuracies rather than...hanging a queen or losing a free piece. You actively have to try to win the game rather than relying on some blunder to get you an easy victory.
Yeah, they do make tactical mistakes (I would know ). But it's rare that I just make a howler out of the blue. Almost always, I'm under some sort of pressure. That's why I say I need to learn how to win games to advance; I can't just shuffle pieces around and wait for a tactic to appear (though that would be nice).
This leads me to thinking about reviewing more master games.
It's easier then it seems to achieve a rating of 2200.
Drawing a 1911! Way to go!!
