kovarex: This problem is practically the same as 181 (I checked the sources to make sure it wasn't an upload error).
The only difference is extra stone at J19, and stone moved from C14 to C13 which doesn't affect any of the variations.
Also the opponent answer was different than in the original problem. So I merged both possible opponent answers into one sgf, with added bunch of refutations, and uploaded the same SGF here. (with the 2 stone changes)
d4rkm4tter: Ok. Yes, there are very few cases like that in the collection. But the player still has to figure out that the same solution still works I guess.
Lyde: On BesoGo I think there is no variation marked as a solution
posetcay: It wasn't easy to find the issue , but it was because of an incorrect refutation sequence to A17 merging corrrect path to the wrong answer. Resolved.
