  <p>Middle- and endgame books are better for the relatively small group of people with a lot of time and ambition.

For this goal, one needs to cover every important aspect of the game and "dive deep", even if it's a chore sometimes. </p>
  
  <p>People with no or not much ambition will most likely never touch any chess book at all. They are probably the biggest group, but irrelevant to the publishers. </p>
  
  <p>However, people who don't have the time, but still some ambition will find that a good(!) opening book will serve them well enough (if it is focused on middlegame plans instead of memorizing lines). They may not learn all possible middlegame patterns (arising from any possible opening), but they will learn the typical middlegame patterns of their opening of choice, and that will probably cover about 70-80% of the games they play. They won't be as easily able to switch opening lines as part of preparation against some opponent, but as long as they get to play "their" opening, they will feel comfortable enough. Likewise, they will lose some endgames because they lack the theoretical knowledge, but again, this will most likely only affect a small percentage of their games. </p>
  
  <p>An important point here is that if they <em>do</em> invest a small amount of time to go to their local chess club's training sessions, opening books get even more efficient: Collective training is more likely to cover universal topics "that everyone should know" like common endgames for example, while opening theory will at most be dealt with very superficially (after all, everyone has to agree on the topic, and it's unlikely they will all like the same opening). This way, one can use the training sessions to fill the most important gaps not covered by the opening book, and use the opening book to fill the gaps of the training sessions.</p>
  
  <p>This third group will most likely not get as good as the first group, but <strong>good enough</strong> for their taste, with considerably less effort. And I'd argue that it outnumbers the first group, and is thus more interesting for publishers.</p>

  <p>Frankly, for most players below 2200 (prodigies excepted), I believe that this is the wrong approach totally.

  <p>Rather than memorizing opening moves where you are on your own when your 1200-rated opponent doesn't know book; it teaches you HOW to play the chess opening, and what you are trying to achieve, in general.

Surely everyone who's played chess several times has had the experience of losing (whether by checkmate or a large loss of material) within just a few moves of starting the game. Sometimes this is via a trappy opening in which we think we are following opening principles, but our opponent's moves render those principles moot. Having experienced this, we may want opening books that show us how to avoid the trap(s) we fell into.

  I think there are number of reasons why these are so popular:
  
  * It is easy to start learning openings. You can read about ideas and memorize some lines. It is not so easy to learn middle game or end game in similar fashion.
  * A lot of players want to get an edge from the start- hence the focus on openings.
  * People enjoy reading them

  It is questionable if middlegame or endgame books are more important. There is an argument to be made that you need something username_0 than books to learn good middlegame / endgame skills. Openings on the username_0 hand can be easily learned from books.
