no. This engine is just lame. It seems to get worse as it searches deeper. It
tends to do odd things. I thought I would see what it thought though. it had the
move at depth 8, but as it searched deeper it went for g1-f1. It would have
taken it forever to return what it thought for depth 13. I'll see what the
newest Storm comes up with.
