I played chess a seriously when I was at school but my family moved to a town without a decent club in last year at school so I stopped playing. Started again around 2.5 years ago and I'm pretty serious. Trying to do 10-20 hours per week of training, seeing a coach for 2 hours/week and entering tournaments (I'm in the middle of one this weekend). I don't play much online, just chess puzzles, books and playing against the computer ( The hard bit with computer chess these days is not "playing better than a grandmaster" but "playing like a nnnn rated human" ). At the level I'm at memorising openings isn't too big. perhaps 20 lines to a depth of a dozen moves is enough. My rating is 1900 FIDE (although I'm probably 100 points lower in real life) which puts me in the top 100,000 players in the world or something like that. My medium term plans are to get a low level title (below grandmaster) in around 3-5 years. It's a plausible goal if I put in the hours.
