I played seriously when I was much younger and knowing how analytical you are, I think you will enjoy the game.
A few years ago I played some live games on yahoo chess....check it out. You can actually play against other players of your ability which will get you a rating..which you could share

in a future post.
One word of caution....tough games take up time.
I would also recommend a book focusing on the strategy on the first 25 moves (the opening). It is pretty much accepted that if you can secure the best positioning control of the board within that time, you give yourself the best chance to dominate and win the rest of the game.
Best of luck!
