The analysis can start with 5 in case that there were previous moves that the
program remember

The following analysis starts with 1 and also has the same problem

http://f23.parsimony.net/forum50826/messages/135163.htm

Fritz9 avoids Ne5 in that analysis earlier but it still likes that move for some
seconds and it still has illogical score.
