The old way is to buy openings books, and study on a real board. Now, you have got the amazing opportunity to practice an opening on line, and get some of you games analyzed. You can then become rather quickly a decent specialist in any opening of your choosing.
How to learn openings?

Does this add anything to what I said?
Hey all,
What do you guys use to learn openings(like some sort of database or a study to keep track and go over all your lines once in a while)
Also should I be learning theory at my level or not?
