This was originally posted by Chess Teacher here: Some traps in the Sicilian game. (In a recent update, dated April 2010, the author prepended an unfortunate note starting with “The method stopped working and the post has been replaced by some images …”.)
I’m re-posting it as a comparison of different publishing methods. I hope to get some feedback about the advantages and disadvantages of each approach from the end-user‘s point of view. For example, how easy and intuitive can we navigate through variations?
