The front of a card has the position (and the moves leading up to it, if an opening) and the back has the correct move, sometimes an explanation, and sometimes a few variations if they're necessary for the answer.

Can you elaborate on "searching for exceptions?", do you mean the process of checking if your move is safe (i.e blunder checking a tactic which looks good at first sight, but actually loses?) 2. When you say you are not sure you have to memorize concrete positions, is this your arbitrary **opinion** (i.e gut-feeling) as a >1900 player or based on some concrete evidence (not trying to be rude, just trying to figure out where you're coming from) 3. Most important question: did Anki help you retain "sharpness" in the long term at all?

  Chess Position Trainer is a software package that uses a spaced repetition method to help you learn moves for both openings and just a selected set of positions. It stores the information to be trained as positions, so move order becomes moot.
  
  This is actually a more useful approach to learning the opening, because move (re)ordering is often used to try to steer the game into a position but avoid disadvantageous variations that can arise if the normal order is chosen. So, the players who are best at both *spotting opportunities for transpositions* and *recognizing when one has occurred* will be best equipped to play the best theoretical move from that position.
  
  Unfortunately, CPT's schedule for repetition is not adjustable. So, if you think there may be some advantage to that, Anki is a good option, as mentioned by Christophe in a comment to another answer.
  
  You will need to load data into both. CPT has the advantage that it will accept a PGN game (or file of games) and produce the required training for the whole suite automatically. For Anki, you would need to setup/import each position that you want to be tested on individually. So, at least in the short- to medium-term, CPT is less labor for about the same benefit.
