I shall pose three suggestions for improvement of Tactics Training: one which I think would be awesome but a bit laborious to implement, and two that are easy to implement but maybe not so important.
Sometimes, the best response to my move is not the one that is hardest for me to answer. Look here:
en.lichess.org/training/61293
In this position, I spotted Nb5, but then the computer answered e5 and it was easy to get Bb4.
On the other hand, the most challenging line (to me) would be a simple Nxf1. After Nd6, Kc7, I would blunder with Rxb7 instead of e5, which is (for me) hard to spot.
I know that lichess administrators can't spend their lives curating tactics training and it is done automatically, but maybe we could do this?
Suggestion 1: Add an option to suggest a response that is harder to spot.
Or:
Suggestion 1': Try to make the computer find the longest line until clear advantage instead of the best line.
Or:
Suggestion 1'': Introduce a "study mode" - the player has to answer all possible responses (without trivial ones, i.e. requiring just one more move to clarify the situation?), up to the point when the advantage is clear.
Two other issues was already addressed in the forums, I think.
Suggestion 2: Do not penalize winning moves, even if they are much worse than the best move. Tell the player to find a better move.
Suggestion 3: Indicate length of a shortest mating sequence. Maybe make it an option.
