How do you control your opponent when using a specific opening

Royalrunner
Relatively new to chess openings, I wonder how a player using his favorite opening can dictate how his opponent moves his pieces. It would seem that every game would have different moves made by different opponents. Different defensive moves would seem to change the opening moves, sometimes after only a few initial moves according to the opening. What is purpose of memorizing a large number of moves, many which may not be relevant? Should a particular defense be used as soon as the opening is recognized? Same questions as above concerning defenses?

  You can never dictate what your opponent plays.Even lines that are forced and indeed dictate what your opponent will play require some cooperation , your opponent can avoid them if he wants.

    Avoid memorisation and learn to think on your own.That way you won't bother to dictate what your opponent's moves , you won't even care , you will have a good response whatever he does.Since at your level hardly anyone will play theory , understanding and thinking is the best way to play openings.

If you were to play e4, there is no way to stop someone from replying a5.
Nevertheless, most people don't play a5. Most of the replies will be e5 c5 or Nc3.

However, if you played d4 as the first move, there are not too many reply options the opponent will consider. In most cases, they will just respond with d5. This kind of controls your opponent, but it will not guarantee that they will respond this way. Again, they might respond a5 just to lead you into dark lines that you will not be familiar with.

It's like that episode of the Simpsons. Whenever they play a move you don't want, they get an electric shock.

Thanks for the comments. I looked at a well known book on openings tonight and reading the first opening material find ten pages of discussion. It goes through each opening move, but after the first few, it gives three or four alternative responses by black. What would be the purpose of trying to learn this material? Also, I see a number of “defenses” discussed. How can you tell what defense to use without knowing what opening white will use?

Excellent question.

Different openings have different typical plans.  In the Spanish, both sides focus on the centre above all else, often with lots of slow maneuvering, and the game is very strategic.  In the King's Gambit, the focus is more on the Kingside and things happen much faster.  In the King's Indian, White tends to play on one side of the board and Black plays on the other; whoever is faster emerges victorious.

People play various openings because they generally enjoy the associated plan.  Most people who play the King's Gambit do so because it gives them positions they like.  As amateurs we mostly play to have fun, and if we can get positions we like then we will have more fun, right?

Also, different openings can keep chess fresh.  Rather than always playing the same opening moves every time, we can mix things up.  Within each opening they are different variations, and these variations have sub-variations.  Each one subtetly changes the nature of the position, and if you understand this you can tailor openings to fit your preferred style or mood, as the case may be.

At the professional level, it is necessary to know these ideas in very minute detail, hence the 10 pages of analysis you've mentioned.  For non-professionals, this is unnecessary.  It can be fun, though, to play the same positions as Kasparov or Fischer or any other chess hero, to follow in their footsteps.

"... Overall, I would advise most players to stick to a fairly limited range of openings, and not to worry about learning too much by heart. ..." - FM Steve Giddins (2008)
"... I feel that the main reasons to buy an opening book are to give a good overview of the opening, and to explain general plans and ideas. ..." - GM John Nunn (2006)
"... If the book contains illustrative games, it is worth playing these over first ..." - GM John Nunn (2006)
"... the average player only needs to know a limited amount about the openings he plays. Providing he understands the main aims of the opening, a few typical plans and a handful of basic variations, that is enough. ..." - FM Steve Giddins (2008)
"The way I suggest you study this book is to play through the main games once, relatively quickly, and then start playing the variation in actual games. Playing an opening in real games is of vital importance - without this kind of live practice it is impossible to get a 'feel' for the kind of game it leads to. There is time enough later for involvement with the details, after playing your games it is good to look up the line." - GM Nigel Davies (2005)

Stay active. Make sure your moves are purposeful. Study variations, recognize patterns. For me it is all about knowing the resulting opening variations better than your opponent. How can you pull your opponent into a line that you know better than him? If you've played out a sideline dozens or hundreds of times and your opponent is playing the position for the first time--or whatever--you have a major advantage.

You can't control them! All we can do is to play as logically as we can.
