AlcherTheMovie - First of all, I think you're on the right track.I've never formally studied just tactics or endgames by themselves - and nevertheless I'm a decent chess player. I put all my time into studying openings. Estragon thinks studying openings is not the right thing for you, because I think he is referring to an improper way of studying openings. At least to me, and maybe I'm not interpreting him correctly, he seems to think studying openings will reward you only with knowledge of memorized moves. However, if studied properly, the study of openings does not partition your improvement to just the first 5 moves.
To really study an opening, you should read articles or books, go over high-level games played in your opening, analyze theory and those games with a strong computer (like Houdini), and finally you need to play the opening. Reading articles and books will give you two things: technical theory, and ideas and problems of the opening. For example, in the Ruy Lopez black often wants to play a6-b5 in order to reduce the pressure on e5. Black's problem piece is invariably the queen's knight, Nc6. Going over high-level games will show you various plans for coping with the various problems and demonstrate common and strong ideas. Analyzing the opening/games with Houdini will help you understand why moves are played and familarize you with common tactics in your opening. Playing the opening will help you find problem lines and give you experience.
Clearly, if you study openings like this you gain a deeper understanding of your openings and improve your knowledge of common tactical operations. Even if you change openings later, you will still have gained an understanding of a position you didn't know before. Also, going over high-level games will expose you to interesting endgames, and show you how to convert wins and hold draws.
Again, Estragon's criticism of opening study is based upon a superficial chess study in general. If you study endgames by memorizing rook endgames, you'll miss out on general conceptions that are important. Openings are arguably the most important phase of a chess game - in order to even REACH a middle game or endgame, you first have to bang out the first dozen moves. If you maximize the strength of those first moves, then you will have a better middlegame/endgame to play. You have to first build a bridge across a river before you can conquer what's on the other side. This is why opening books are popular: Chess players value them. I don't think GMs deserve to be portrayed as greedy bloodsuckers because they provide material people value.
By the way, I'm not saying studying general middlgame themes, tactics, and endgames by themselves is bad, or worse than studying openings necessarily. I'm just saying that studying openings is certainly not "wrong" as several people have expressed.
Greetings to all !
First of all , I'd like to thank you all for participating in this thread , your comments really helped me in my opening repertoire .
I'm happy with my choice of openings now , I found many of your tips very helpful when I finished my opening rep . Also , I realloted my study time , I now focus on practicing tactics and developing positional skills through reviewing GM games and playing . I occasionally check FCO for more info when I'm a bit confused in my lines , so I can refresh and broaden my opening knowledge once in a while .
All in all , thanks for everyone ! I'll see you around !
