Is there a theory trainer that helps you practice openings?

I want to learn some theory but it's difficult memorising all the variations and move orders! Is there such a thing as a 'theory buddy' that lets you input the theory you want to learn e.g. London system and then the specific lines in that system you want to learn. Then it goes through variations one at a time and if you get it right it moves on? Much like a quiz were you get instant feedback on your answer. 

I think that active recall is the best way to learn rather than passively reading openings but I haven't found any software that does this. Help! 

Thanks in advance,

Jay

"... for those that want to be as good as they can be, they'll have to work hard.

Play opponents who are better than you … . Learn basic endgames. Create a simple opening repertoire (understanding the moves are far more important than memorizing them). Study tactics. And pick up tons of patterns. That’s the drumbeat of success. ..." - IM Jeremy Silman (December 27, 2018)

Once one has chosen openings, I think that there is wide agreement that the way to start is by playing over sample games. Some of us think that it can be useful to use books like First Steps: 1 e4 e5 and First Steps: Queen's Gambit

as sources of games with explanations intended for those just starting to learn about an opening. Be sure to try to use the openings in games in between sessions of learning. Most of the time, one faces a position with no knowledge of a specific move indicated in a book. One has to accept that as part of chess, and think of opening knowledge as a sometimes helpful aid. After a game, it makes sense to try to look up the moves in a book and see if it has some indication of how one might have played better in the opening. Many opening books are part explanation and part reference material. The reference material is included in the text with the idea that one mostly skips it on a first reading, and looks at an individual item when it applies to a game that one has just played. Resist the temptation to try to turn a book into a mass memorization project. There are many important subjects that one should not neglect because of too much time on opening study.

"... 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)
"... Everyman Chess has started a new series aimed at those who want to understand the basics of an opening, i.e., the not-yet-so-strong players. ... I imagine [there] will be a long series based on the premise of bringing the basic ideas of an opening to the reader through plenty of introductory text, game annotations, hints, plans and much more. ..." - FM Carsten Hansen (2002)

"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)
"... Review each of your games, identifying opening (and other) mistakes with the goal of not repeatedly making the same mistake. ... It is especially critical not to continually fall into opening traps – or even lines that result in difficult positions ..." - NM Dan Heisman (2007)

"... Once you identify an opening you really like and wish to learn in more depth, then should you pick up a book on a particular opening or variation. Start with ones that explain the opening variations and are not just meant for advanced players. ..." - Dan Heisman (2001)

IMBacon and kindaspongey,

I appreciate your responses and helpful advice. This is not my serious account; I mostly play bughouse  and the ratings on it are not an accurate reflection of my ability, in fact other people play on this account also. I acknowledge and agree that understanding the moves is far more important than memorising them, but what I was asking for in my original question was if a theory training software exists.

I ask this because whilst study of ideas is good, actively recalling some specific theory lines e.g. a complicated multi move opening trap is better for remembering them when they are needed! Active recall and spaced repetition are the scientifically proven best methods of memorisation. Since asking this question I have discovered something that is similar to what I am looking for in case you are confused:
