Your story sounds familiar, it is only after you encounter good players that reality hits :).
For me I was winning and eventually ventured out of my comfort zone to a club and met my worst nightmare, the chess clock!
After loosing consistently to time pressure I decided to study chess and improve my game.
I recently joined this site and I am yet to tap into all its perks and resources. However I am getting there.
I now feel good about my game, well that is until I reach my peak and have to struggle to improve all over again ..lol..
I started playing chess with my brother when we were kids by taping the names of the pieces on top on top of checkers. knowing little to nothing of chess theory i played occasionally up through the years. after high school i moved away from home and lived with some friends who were avid players. it would have beneficial except we were also avid drinkers and often combined the two. for the next decade or so i continued to feed my sporadic interest in chess by playing mostly against computer players and occasionally friends and family, and again playing but not really knowing what i was doing. learning how to not make blunders but not really having a solid game plan from the beginning. it is only now after playing chess for roughly 25 years and 7 months after joining chess.com that i can say that i am finally starting to get it. being able to explore my past games and study book openings as well as the much used tactics trainer provided by this site, my game finally has improved to a point that i can confidently play human opponents with pride in my game.
