More aggressive and more positional but less tactical and has some unsound (but
in my opinion fun) chess knowledge.  In the positional.epd test I tested with
Toga got 57 points out of 113 Fruit 2.1 got 63 points and Gambit Fruit 4bx got
71 points.  I think Fruit will pass both engines both positionally and
tactically soon though.  It is only a matter of time until Fabian shocks the
computer chess community again in my opinion.
