1. You never "know" an opening, you can only hope that you "know" it better than your opponent.
2.At the beginning of your chess life it is a good idea to play a lot of different things. That way you learn about different kinds of structures and plans. Later on it might be a good idea to specialize a bit, but by then you'll really know what kinds of positions you like, so your choice will be better.

This is a program that lets you input your opening repertoire into a database and then drill the positions like a tactics puzzle. Another good way to go is to go over many games played in your chosen openings, and buying some good books written on said openings.
hello,
i have some questions about creating an opening repertoire:
1. when can i say that i actually "know" a specific opening? its when i know all the best lines until the middlegame against any move even the weaker ones?
2. why is a good thing to know a lot of openings? why not to stick to some that i always play? why its not a waste of time to learn opening that i might barely use?
3. there is a good way to document my progress in learning an opening?
4. there is a good metod to learn openings? maybe a recommended study program?
its just that i am going to start learning this phase of the game (after train a lot in tactics, and learn the basic endgames)
thanks in advance for the help
