In the tactics training over at CT, do they give you human-written annotations with explanations for any of the tatics problems/puzzles? Especially the more complicated ones? Does TT on this site do the same?
As far as Chess Tempo, it depends what you mean by "they". There are no official variations for non-accepted solutions. However, users can and often (generally) do cover this stuff in the comments. And sometimes they will include boards as well illustrating the variations. If you are confused about a "why not X" variation, excellent chance the comments fully address it. Its random, since its not official, but its generally a very helpful group.
