How To Choose An Opening
This post is not designed to help with the technical aspect of chess so much as the psychology of your opening repertoire. On to the post. I believe that as long as on opening EXISTS, it can't be bad to play against human competitors because IF IT WERE A LOST OPENING IT WOULDN'T EXIST! That said, what you must know is as follows: In order to correctly play any opening,you must know what your line gives both you AND your opponent. For example,if you play the Sicilian Defence with black, you should be expecting a sharp tactical game where your opponent will constantly be trying to threaten your king, while you counter with a queenside attack. If you are a practitioner of the King's Gambit, you need to generate an attack quickly before your opponents material edge overwhelms you. The point I'm trying to make is that you should pick an opening not because it's played the most, or objectively best, but because you are comfortable with the position that follows. Also, don't be put off by how Rybka evaluates a position.If for example Rybka evaluates the king's gambit at -0.73 (which it does by the way) then does that mean your game is terrible with white? A resounding NO for two reasons: 1. Rybka is an engine, not a human, and although rybka's assessment of the position may be technically "correct," more than likely your tournament opponent will not be Rybka 4! 2. If you enjoy the resulting position after the King's Gambit has been played, then you should know that it has been played thousands of times by top GMs with mixed results for both sides. This is the case with any opening. I will conclude in saying this. If you enjoy quiet positional games you should consider playing d4 openings. If you prefer more aggressive tactical struggles you should consider opting for e4. I will not tell you which specific lines to play because it's all a matter of preference, and only you can tell which line is right for you.
