Both Shredder and Fruit bounce back and forth between Bxf7+ and Nxb5.
The bishop move is prettier, I must admit, but the Knight move seems a lot less
error prone to me.  I am sometimes keen to the king safety type of moves, but
really this one is a bit beyond me why the Bishop move is better.  The knight
move seems obvious enough.  Both moves seem to be pawn grabs, but the Bishop
move is a lot less obvious as to why it works to me and I would be afraid of the
complications.
