I'm more of a "random" than "structured" person, but I can offer a bit of advice. I'm rated between 2000 and 2100 OTB, by the way.
1) At your playing strength, tactics is likely to be your main weakness. Practice tactical exercises (pins, forks, skewers, guard destruction, decoying & diverting, sealing & sweeping, line opening & line cutting, etc). Familiarize yourself with model mating patterns (corridor mate, smothered mate, lolli, greco, morphy, paulsen, andersson, epaulette, broken fianchetto mates, etc).
2) When it comes to studying the opening / middle game / endgame, work from both ends towards the middle. You can't reach a playable middle-game position unless you understand a bit of opening theory... and you won't know how to win a won middle-game without a bit of endgame study. Leave the middle-game study until you feel at least marginally competent at the opening and endgame phases.
3) Middle-game planning is largely determined by the Pawn structure. Focus your middle-game study - at least at first - on understanding this relationship. Get aquainted with the Pawn chain, the wedge, the phalynx, the lever, the ram, and with typical Pawn weaknesses such as backward or isolated Pawns and weak color complexes.
Long story short I've known the basics of playing chess since I was a kid, but at that time I didn't know much beyond the rules of the game. In my mid-teens I started reading up and learned essential ideas about things like controlling the center, rapid development, castle early, etc. But it wasn't until recently (I'm 34 now) that I really started taking the game seriously.
I would like to get involved with tournament play, but I've been wondering exactly how to go about training myself. Thus far, I've mostly just done a bunch of scattered training from a variety of sources: Chess for Dummies, Lev Alburt's first Comprehensive Chess Course book, random YouTube vids, chesscademy.com and of course chess.com. Oh, and I also have Bobby Fischer Teaches Chess.
What I really want to do however is put together a logical training path that builds upon itself systematically. So I ask you now, how do you study the game of chess? Do you have a structured training regimen? And what advice can you offer to someone who is trying to put such a thing together?
Thanks in advance.
