Yes please. I've just hit "hint" on my current game and it tells me that there is a "Single possibility" for 3 (position a). However looking at the actual grid, there are at least 2 other equally valid places that it could go (position b and c).
_b9 15_ __7
156 247 839
a7c 69_ _51
568 314 972
79_ 582 __3
___ 976 58_
_8_ 761 395
615 439 728
937 825 ___
As such, I haven't got a clue on how it actually came to that conclusion and it doesn't teach me how to better myself at Sudoku.
