I am mid-Class A, not expert :) Though 2 of my last 3 tournaments have been at Expert stregth performance, one nearly Master. But I figure my true strength is still class A. I have too many holes in my game right now to justify being an Expert.
At age 39 years, 11 months I was still class C despite reading lots of books and even having an IM coach in college. I took many years off after college as career, family and life just were more important.
In the past year and a half (6 months ended up working 70+ hours a week, and this interrupted my study) I decided to focus more on chess and develop my own plan.
I study a TON of tactics. In the past year I averaged 3-4 a day on chesstempo. In the past two months, I've averaged 9-10. I spend an avergae of 3-4 minutes per tactic, so that is 30-40 minutes a day. Chesstempo has a mobile app now, so I can get my tactics in during situations I normally would be wasting time.
Every day I wake up early and spend 20 minutes or so studying my opening repetoir using Chess Position Trainer. I'll review lines to make sure I still have them down.
Every game I play, blitz or not, I download and study on SCID. I review my openings to see where I make mistakes. If I make mistakes I re-review the line. I look for common errors and misunderstanding of positions. For example, If in my head I think I am better, but computer says I am weaker, then I try to understand why. And I do play a lot of blitz even though I am not good at it to force me to get better at my quick judgement and opening play.
I'll review master games from chesstempo as well and use SCID to fast forward through ten or twenty in one setting. IM Silman says when he was a kid he'd go through hundreds... not sure how he was able to do this on a normal board... the PC makes it so much easier.
If I see a position where I missed a tactic, I load it onto chess position trainer so it will test me periodically.
I am also studying with a friend via Skype, going through Silman's endgame book.
Slowly I am improving... about 100 points higher on tactics trainer and a few hundred in USCF.
Also, this might sound silly, but I swear it helps. Exercise. I've done light weight training and jogging almost every day to help keep me fit and adopted a strict bedtime routine. Eating better and staying away from junkfood (mostly) and having light snacks and water throughout a tournament also helps.
And the most important part of my training. Not wasting energy on crap that doesn't help me. chess.com videoes have never helped me (not criticizing, just saying they don't work for me) and opening books.
It's been over 48 hours since this thing started, just another 23 games to go! Happy 4th of July! Also, I was wondering if I could pick your brain about how you got to your current level of play? I've been playing sporadically for many years and only in the last few years have I played on a regular basis. I was wondering what key thing(s) would you contribute your success to? You say you have trouble visualizing. How were you able to get to expert level having this issue? I feel like I'm on the cusp of a similar breakthrough and might be able to finally achieve a life long goal of mine to get to expert level or better.
I look forward to your response!
