If that's correct, then still the judging is incorrect.

Stefan says that the result is determined by the last search.
If the last search is > 3.0 then it's 1.0, if it's < -3.0 then it's 0-1
otherwise seen as a draw.

So then the other posted game should have been judged as a draw as
last score is 0.60. However it scored it as a win for Shredder...
