I would like to see Chess Mentor courses with Multiple Choice questions (i.e "Look at this position and evaluate it. WHo is better and why?" etc).

That would make it easier, and allow you to guess. You need to be able to show the answer without multiple choice so that they know you know it.

Farbor, the feature you are seeking already exists. You need to open any database with GM games, pick games with complex openings or middlegame battles and then take any position from those games and put it for infinite analyses to rybka3. Set 10 or 20 multiple lines to show up and hide it from the view, wait several minutes while engine works and after that you may guessing what is little better or little worse and why exactly (it will show the reason), or you may just left all lines shown to explore them and study. So, there is no need to invent the weel again, that is why there are no such courses in mentor. That is only imho of course.

       Same thing goes for chess.  Take a test.  Then forget it.  So, who cares if it is easy or hard?  Do we get an associates' degree in chess technology?  Do we get graded?  Do we get certified?  What's the deal?

Rybka will find good moves but is perpahs not as good as verbalizing (if that is a proper word?) the thought process that will help you to find the proper move.

There are a lot of books with very detailed explanation of all this process and many possible algorythms. There is complete assortment of any kind - all stages of the game, all different position types, all different patterns and so on. I read only one such a book so far, but like it a lot. It's Kotov's book about move calculations, don't sure how it's name in english, something like "Think like a Grandmaster" or similiar. It is 1970 year book, the original name is "Тайны мышления шахматиста". But probably you want some book about proper planning in undefined position types, insteed of that one.
