You have played a total of 7 games here. Give yourself a little more time, say at least 50 games before you start worrying about your rating.
You don't know where you will end up. You could have just run into some other up and comers. Look at this game against Computer Impossible. I would say your resignation was premature.
Those were real rating points you just blew off with your resignation.
I know I'm missing something from my chess game. My low rating, on here and OTB, proves that. I'm just not sure what it is. I've learned the principles (develop, control the center, etc.), read Amateur's Mind to pick up positional concepts, done some puzzle books, played Tactics Trainer, etc. I don't want to act like I'm "entitled" to a higher rating after doing these things, but I feel like my playing strength should be higher than 1000-ish, especially when I see people with way higher ratings who don't know anything about positional play or openings. I'd like to get to 1500 level, but for some reason it just isn't happening. What gives?
