From the answer to my question How are PGN ambiguities handled?:
In the case of ambiguities (multiple pieces of the same type moving to the same square), the first appropriate disambiguating step of the three following steps is taken: ...
After reading that, a new ambiguity surged from that disambiguation, it is not clear what would happen if the pieces that look like they can move to a same square are all pinned except one piece, is then a need to disambiguate even if only one of those pieces can legally move in there?
Here is an illustrated example:
[FEN "4k3/8/8/8/8/8/8/q2NKN2 w - - 0 1"]
Should I use Ne3 or Nfe3?
