paul: 16.Tc4 T8b3 (2020-11-03)
A.Buchanan: A nice trick for the parser which builds the animation would be to spot when a move is ambiguous. So here 16. ... Tb3 needed to be fixed to be 16. ... Tbb3. In this case, the animation guessed wrong and later reported that 19. ... Da8 was impossible. However in some cases, the error might not be picked up by a later illegal move, yet it could still be important. I will request that Gerd have a look at fixing this ancient issue. (2020-11-04)
A.Buchanan: 22.Tc8 was also imprecise, but did not cause a later illegality so there was no clue. Comparing the diagram at the end of animation to the start diagram would not necessarily be sufficient even for proof games, and completely inadequate for forward stipulations. It’s the parser can best nail these issues on a per-move basis. I’ve emailed Gerd (2020-11-05)
A.Buchanan: Gerd has fixed this: announcement 2020-11-7: The solution engine now no longer plays moves with ambiguous move notation in order to ensure that unambiguous solutions are added.
Thanks so much, Gerd! (2020-11-08)
