Package: gnuchess
Version: 5.07-7
Severity: important
Maybe I'm missing something, but while I was testing
the move generating routing of my chess engine against gnuchess, I found in
a sample game that gnuchess made an ambiguous move. That is, the notation
used does not clarify which piece is to be moved.
The ambiguous notation is Ncd5+ instead of what
I think would be correct: Nc3d5+
Below follows the full game report.
