It depends on what you want to accomplish. The goal of chess is not to become so good that you can win all the time. I am an average chess player now and can usually surprise people rated higher than me when I play them. My advice is to play about 10 chess games and learn from them. If it was a lost, find out where did you start losing. If you won, how did you win. If you can understand why you win some games and lose others then you are becoming a better chess player. Start playing chessbase 9 on easy and see if you can win. Most chess computers are quite strong even on easy. Read as many chess books as you can and learn from them. As far as openings you don't need any for white or black, just start with the center pawns or the pawns in front of your king and queen. Remember that each move must have a purpose and you will avoid making bad moves that give up your piece for free.
Learn the scholar's mate (4 move checkmate) and the fool's mate (2 move checkmate) (see fool's mate picture in my profile) these are common beginner traps that beginners fall into. Fool's mate can easily be prevented by not moving the f-pawn or the pawn in front of the bishop on the king's side on your first move.
I was a beginner, but learn to become better through playing many chess games and learned why I won/lost each one. Any questions? I will be happy to help if I can.
So I´m a beginner, I was hoping you could advice me about how I should begin studying, what I should get and read, what is enough. Something for me as a beginner and then something I could use as I learn more.
I have chessbase 9 and am starting to use the opening key and the other methods, or learn to read it, understand it rather. Is that enough even on expert level, chessbase?
Where should I start, I just can´t decide, so much stuff to choose from :/
