When I reached my peak rating, I was at the top of the local pool. Had I invested more resources in traveling to tournaments where I could face stronger opponents, my improvement would have continued. I know a lot more about chess than when I was at my rating peak, but I do not focus as well. Part of it is due to age; part due to motivation. My priorities shifted from self-improvement to helping the young players of my city reach and exceed my skills. Some have.
My overall record shows how rarely I’ve had opponents over 2000 in a quarter century of tournament play. In contrast, on chess.com I often face titled players in blitz and correspondence chess. I have dozens of wins over such players and my peak blitz rating was this month (2066).
My USCF standard rating graph. I played in my first USCF event at age 35 in early 1996. I had been playing chess with a sense of purpose since 1975. In the late 1970s I studied chess constantly, focused on openings and reading tournament books. The players who inspired me at that time were Gligoric and Karpov.
