Wouldn't that be about remembering specific tactics, instead of trying to find a new solution to a new problem using the patterns you know and the calculation skills you have? I would strongly recommend the latter.
Usually, in my experience, people doing tactics want to do fresh tactics to sharpen their skills, not old tactics to try their memories.
For the tactics trainer program, I was thinking that having the option to choose to play only tactics you've failed in the past in order to try and inprove faster and learn from your mistakes might be a good idea. Would that be possible?
